Scans without a text layer cannot be searched, copied, or read well by assistive tech. Most “free OCR” sites upload every page to a cloud API. SortMyFile OCR PDF runs Tesseract in your browser, merges searchable pages, and lets you find text with Cmd/Ctrl+F — without sending document pixels to our servers.

Why does OCR download language packs on first run?
English language data may download from a CDN once, then cache in your browser. That is model delivery — your PDF pages stay on-device for recognition.
When should you OCR a PDF after compressing it?
Heavy compression often rasterizes pages and kills selectable text. If the scan is still readable, OCR can restore a searchable layer for archives and accessibility.
What limits OCR quality on scanned PDFs?
Free tier caps OCR pages per day so tabs stay usable. Typed scans work better than messy handwriting. Skewed or dark photos reduce accuracy — straighten and brighten first when you can.
Is searchable OCR the same as full PDF/UA compliance?
Searchable text is a major accessibility win, but tagged PDF/UA for complex layouts often still needs desktop publishing tools. Pair OCR with alt-text PDF flows when you assemble image packets.
