Frequently Asked Questions
Is it free?
Yes. No signup required.
Is my file safe?
Yes — your PDF is processed entirely in your browser and never uploaded.
What does make searchable mean?
Each scanned page gets an invisible text layer added behind the original image, so you can search, select, and copy text in any PDF reader — the page still looks exactly like the scan.
How long does it take?
OCR runs in your browser, so it depends on your device and the page count. Expect a few seconds per page — a long scan can take a minute or more.
How accurate is the OCR?
Good for clear, high-resolution scans and printed text. Handwriting, skewed pages, low-quality scans, or unusual fonts reduce accuracy. It runs entirely on your device, so it won't match paid server-side engines on difficult documents.
Which languages are supported?
English in this release. More languages can be added in a future update.
Does it work on PDFs that already have text?
Yes — it works on any PDF, but it's designed for scanned or image-only PDFs. If your PDF already has selectable text, you don't need OCR.
Max file size?
100 MB.
