PDF Highlighter & Markup

Make your highlights count

Highlight what matters in a PDF, then save or share a marked copy while keeping the original unchanged.

Available on Android, iPhone and iPad. Open a document and draw freehand highlights or straight lines on the page. Choose colors and thicknesses, zoom in to read, and revise your marks with the eraser and undo.

Keep your place. Save a marked copy.

Your work is saved on your device. Reopen a recent document to continue with its saved highlights and last page. Android keeps saved documents until you delete them; iOS keeps up to 5 recent PDFs and removes older in-app copies. Use Save to keep important work outside the app.

Save and Share create a new PDF with visible highlights without changing the original. You can open password-protected PDFs with the correct password. Unlocked working copies and exported PDFs do not retain the original password protection.

Before you start

Highlights are drawn directly on the page. The app does not offer text-selection highlighting, OCR, text editing, text notes or form filling. In-app storage is not a backup service. Keep separate copies in case you uninstall the app, clear its data or lose your device.

PDF contents are processed on your device. If you choose to send a support attachment or share a file with another app, the recipient receives that file. See the Privacy Policy for ads and version-specific analytics and diagnostics.
