What's New in Secure PDF Tools

One PDF highlighter, three flexible ways to mark a page

• Text: drag across selectable words to highlight the exact passage you need.
• Rectangle: mark clauses, form fields, diagrams, or areas on scanned pages.
• Marker: draw a natural freehand stroke over any part of the page.

Choose a color, adjust its strength, move or resize existing marks, and use Undo or Redo while you work.

Keep the original text searchable

Highlights are added as transparent page artwork, so the tool does not turn the original text into an image. Existing selectable text stays selectable and searchable in the finished PDF.

PDF documents are processed on your device and never uploaded to our servers, making Highlight a practical choice for contracts, reports, study material, forms, and other confidential documents.

Reuse highlights across matching PDFs

Apply a mark to every page, save the setup for later, or use Batch Apply on wider screens to highlight the same positions across matching PDFs. Reused text highlights follow their saved page positions; they do not search each new document for matching words.

Add Highlight to a custom PDF workflow

Highlight is also available as a Workflow Builder Action. Place it after steps such as Crop or Reorder Pages, preview the document at that stage, then continue to signing, page numbering, compression, or any other supported Action before saving the final result.

Smaller PDFs. Your documents stay on your device.

Compress confidential client reports and everyday attachments without sending their contents to a file-processing service. PDF documents are processed on your device and never uploaded to our servers.

Images are compressed, not removed. Existing selectable text stays selectable and searchable, and page layout, links and bookmarks are preserved. The tool also removes extra descriptive information stored inside the file and packs existing data more efficiently to save space.

Choose your balance of file size and clarity

• Gentle: keep more image detail with lighter compression.
• Balanced: the recommended starting point for everyday sharing.
• Strong: reduce image quality further when a smaller file matters most.

Stronger compression can soften fine detail and shift colors slightly. Check small print in scans in the result preview, then download your PDF and see the actual saving and image changes.

Real files, substantial savings

In a three-file test, Strong compression reduced file sizes by 29.5%, 47.0% and 73.1%. One PDF went from 7.94 MB to 2.14 MB, with readable pages and its layout retained. Results depend on the document; already compact PDFs may not shrink.

Compress multiple PDFs with a reusable workflow

Add Compress PDF after your edits in Workflow Builder, then save the finished document without downloading and reopening intermediate files. Save your workflow and use Batch Apply on wider screens to run the same setup across matching PDFs.

Create a PDF that feels better to read

• Soften bright white pages with Warm Paper, Sepia, or Soft Gray, or create a PDF dark mode with Dusk or Night.
• Keep text selectable and searchable after changing its color and the page background.
• Keep images and graphics unchanged, or invert supported photos, scans, and vector artwork so they suit Dusk and Night reading styles.

• Remove an outdated logo, image, or piece of artwork before sharing a PDF.
• Erase selected content from a report, form, or presentation.
• Remove all raster images when a text-and-artwork PDF no longer needs them.
• Add Remove Content to a workflow before the next PDF Action.

How to remove PDF content

• Click content or drag a rectangle around it, then review the selection before saving.
• Choose Remove all images when every raster image in the document should be removed.
• Use the Remove Content Action in Workflow Builder to remove all images as part of an ordered process.
• Review the edited page, then download the cleaned-up PDF or continue to the next tool.

• Crop pages, resize them, and add page numbers in one ordered workflow.
• Reorder a report, remove unwanted pages, and sign the finished document.
• Straighten scanned pages, then make their text searchable with OCR.
• Reuse the same ordered workflow across matching PDFs with Batch Apply.

How to build a PDF workflow

• Open a PDF, then add only the Actions needed between Open PDF and Save Result.
• Place Actions in the order they should run, such as Straighten before OCR.
• Select any Action to adjust its settings and preview the result at that stage.
• Save the final result directly, or use Batch Apply for other PDFs with the same layout.

• Collect invoice numbers, dates, suppliers, and totals into a spreadsheet.
• Turn recurring form fields into consistent Excel or CSV columns.
• Check missing values before sharing extracted records with your team.
• Reuse a field recipe across matching PDFs such as invoices, statements, or forms.

How to extract PDF fields

• Start with a representative PDF whose field positions match the documents you want to process.
• Draw one fixed region for each value, then choose whether it is text, a number, a date, or money.
• Review blank or invalid values before you export the completed rows.
• Save the field recipe and use Batch Apply for matching PDF layouts.

• Turn a selected PDF page into a PNG for a slide, document, or image-based workflow.
• Export product sheets, diagrams, or reference pages as separate image files.
• Create print-ready page images when a PDF is not the required delivery format.
• Convert the same selected page positions to PNG across recurring PDF batches.

Choosing image quality

• Choose Standard quality for smaller images that are quick to share.
• Use High quality for a balance of sharp detail and file size.
• Choose Print quality when the images need extra resolution for print or close inspection.
• Selecting more than one page downloads a ZIP containing one numbered PNG per page.

• Crop and rotate phone-scanned forms before sending them.
• Sign PDF contracts and approval documents from a phone or tablet.
• Merge, reorder, extract, or delete PDF pages while away from a desktop.
• Make scanned PDFs searchable with OCR in a mobile browser.

How the mobile PDF workspace works

• Start in View mode to scroll through pages, then choose Edit when you want to place or adjust content.
• View and Edit modes let you switch between scrolling and touch editing without accidental changes.
• Open Pages, Settings, More, or View from the compact workspace whenever you need contextual controls.
• Batch Apply and exact zoom input remain available on wider screens.

• Make a high-resolution scanned report searchable with page-by-page output.
• OCR invoice packs and form bundles without assembling the full finished PDF before writing begins.
• Keep the original scan appearance while adding a searchable text overlay.
• Batch apply the same OCR setup to recurring PDFs with streamed output files.

Tips for OCR on larger scanned files

• Use Overlay mode when you want to keep the original scan appearance and add selectable text.
• Use Text-Only mode when reconstructed searchable text is more useful than the source page images.
• Page limits still apply: up to 20 pages for free users or 100 pages for subscribers.
• Large or complex scans still depend on your device and browser resources, so keep enough free memory available.

• Remove cover sheets from the start of recurring reports.
• Delete trailing terms, notes, or blank separator pages from the end of a PDF.
• Find and remove pages containing a repeated phrase such as "Draft copy".
• Clean scanned batches with empty-page detection after separator sheets are scanned.

Tips for faster page cleanup

• Use Delete first N pages when every file starts with the same cover or routing pages.
• Use Delete last N pages for recurring footer packets, terms pages, or appended notes.
• Use Delete by text to find pages with a phrase; ? matches exactly one changing word.
• Text matches are highlighted in the preview so you can confirm the pages before download.

• Convert a large batch of JPG, PNG, or WebP images into one PDF.
• Turn a phone-scan folder into a single searchable PDF.
• Build receipt, invoice, letter, or field-note PDFs from image batches.
• Create flattened image PDFs from photo sets when text should not remain selectable.

• Convert photographed paper forms, receipts, and letters into searchable PDFs.
• Assemble a folder of phone scans, camera photos, or document images into one PDF document.
• Clean high-contrast black-and-white document scans for archival or printing.
• Make receipts, printed letters, and typed notes searchable with OCR.
• Create properly sized A4 or US Letter PDFs from batches of photographed pages.
• Send converted photo PDFs into other tools for further PDF processing.

Tips for converting photos to PDFs

• Use transparent backgrounds or consistent surfaces for best page boundary detection.
• Use the independent image cleanup, corner detection, and orientation settings for each scan workflow.
• Choose Clean white to neutralize photographed paper while preserving colored marks, or Black and white for text-heavy pages.
• For folders of images, they will be processed in natural filename order.
• If page detection is uncertain, try adjusting lighting or using the manual corner adjustment.
• Combine with OCR to make printed text in photographed documents searchable and selectable.

• Separate merged invoice PDFs by repeating title text such as "Invoice was issued".
• Split statement packets where each account section starts with the same heading.
• Break combined form exports into individual files when each record has a shared label.
• Review highlighted text matches before downloading the generated split files.

Tips for splitting by text

• Use an exact phrase when every new document starts with the same title.
• Use ? when one word changes between documents, such as "Invoice ? issued".
• Apply Split by text after manual or fixed-page split points when the text pattern should replace the previous setup.
• Matched strings are outlined in blue on the preview so you can confirm where each split starts.

What changed

• Smooth each line is enabled by default for OCR Text-Only Mode.
• Smooth whole page uses one consistent font size and family across the page.
• Do not smooth keeps the per-word OCR font detection signals when you want maximum variation.

• Add a company logo to PDF reports, proposals, and client documents.
• Place scanned initials, signatures, or approval stamps on PDF forms.
• Add transparent seals to certificates, legal documents, and official letters.
• Batch add the same logo watermark or reviewed stamp to recurring PDF exports.

Tips for adding images to PDFs

• Use transparent PNG files when the logo, seal, or signature should sit cleanly over existing page content.
• Choose Fit whole image when the full logo must remain visible inside the selected area.
• Use Fill stamp box for photo-style images where cropping the edges is acceptable.
• Set up one PDF first, then use Batch Apply when the same stamp belongs on many files.

• Pull signature pages from contracts and save them as a clean attachment.
• Save one page from a PDF application, form packet, or long report.
• Extract invoice and receipt pages from monthly scan batches.
• Batch extract the same page positions from recurring statements or exports.

Tips for extracting pages

• Click pages in the visual preview so the selected output is clear before download.
• Use one combined PDF when the selected pages belong together, such as contract signature pages.
• Use separate page files when each extracted page needs to become its own attachment.
• For recurring reports or statements, configure one file and Batch Apply the same selection to the rest.

• Split recurring scanned batches into fixed-size groups with Split every N pages.
• Create one split recipe, then Batch Apply it across multiple PDFs.
• Preview the output document ranges before downloading the split files.
• Review or edit the processing config before starting a batch split run.

Tips for batch splitting

• Use Split every N pages for uniform packets such as invoices, labels, or scan batches.
• Use visual split points when each source PDF has custom document boundaries.
• For Batch Apply, configure the first PDF, then add the other PDFs in the batch dialog.
• The batch result downloads as one ZIP containing one split-results ZIP per input PDF.

• Turn selectable PDFs into image-only documents before external sharing.
• Flatten forms, annotations, stamps, signatures, and drawings into fixed page images.
• Create scanned-style PDFs without printing and scanning paper copies.
• Set up one file, then press Batch apply to include it and add more recurring forms, evidence packs, invoices, or finalized reports.

Tips for better flattened PDFs

• Use balanced quality for everyday sharing and high quality when the PDF needs to print cleanly.
• Run Hide or Add Text first when the final visual page should include redactions, labels, or stamps.
• Upload the first file, adjust the flattening quality, then press Batch apply and add the other documents for the batch.
• Flatten after OCR only when you intentionally want to remove selectable text from the final copy.

• Fix sideways scanned pages before sending them to clients or colleagues.
• Correct upside-down invoices, forms, and handouts for easier reading.
• Normalize mixed portrait and landscape pages in exported reports.
• Apply the same rotation recipe to batches of recurring scans and exports.

Tips for better rotation fixes

• Use Apply to all pages when the whole file needs the same 90-degree turn.
• If only some pages are sideways, rotate those pages individually in the viewer.
• Use batch mode to apply the same rotation setup across multiple PDF files in one run.
• Fix page orientation before OCR so searchable text matches the reading direction.

• Make scanned contracts searchable so teams can find key clauses quickly.
• Copy text from invoices, receipts, and forms instead of retyping them manually.
• Build searchable archives from scanned reports, books, and paper records.
• Apply the same OCR setup to batches of recurring scans, invoices, and forms.

Tips for better OCR results

• Choose the document language that best matches the scan for better recognition quality.
• Choose Lines or Words under Show overlay, then click a highlighted box to correct recognition errors before export.
• Crop to the text region when borders, stamps, or photos interfere with recognition.
• If a scan is crooked, keep Auto align content enabled so OCR straightens pages before recognition.
