How We Convert Scanned PDF Images into Live Editable Layers

When paper documents are scanned, the resulting PDF is essentially a collection of flat photo snapshots. You cannot click on lines or edit words with traditional PDF viewers because there are no underlying text fonts or character streams.

Our browser engine uses WebAssembly OCR to analyze the geometry of each word, detect font families, size, and line heights, and place matching editable text layers over the canvas. You can click any word to modify it, rewrite sentences, correct names, or adjust figures effortlessly.

Frequently Asked Questions (FAQ)

How does OCR make a scanned PDF editable?

Optical Character Recognition (OCR) scans the pixels of your uploaded document image, detects individual character shapes and words, and generates live, editable text objects exactly over the original image coordinates.

Can I rewrite whole sentences or change numbers on a scanned certificate?

Yes! You can click on detected text blocks to rewrite words, fix typos, modify dates, or use the Erase tool to whiteout old figures and type new ones.

Does this work on mobile phones and tablets?

Yes. Our client-side editor runs smoothly across Chrome, Safari, and Edge on iOS, Android, macOS, Windows, and Linux.

Are my scanned documents stored or uploaded to cloud servers?

No. All OCR analysis and editing operations execute 100% locally in your web browser memory. Your documents are never uploaded to any remote server. You can also read our complete walkthrough on how to edit a scanned PDF document.
