About OCR

OCR (Optical Character Recognition) extracts text from scanned documents and images. For best results, use high-quality scans and select the correct language(s).

Practical guide

Why choose local processing?

Scanned PDFs can contain contracts, invoices, identity details, or internal business information, so keeping processing in the browser reduces exposure.
The website tool is free to use with no usage limits and does not require sign-in.
Local processing also keeps iteration fast: adjust options, preview the result, and export a searchable PDF without waiting for an upload queue.

Best files for this tool

Best for PDF files that open correctly in a modern browser and are not intentionally damaged or restricted.
Works well for everyday business, school, legal, finance, and personal documents where you need a searchable PDF.
For very large files, close unused tabs and process one batch at a time so the browser has enough memory.

Common limitations

Encrypted or permission-restricted PDFs may need to be unlocked before processing.
Scanned pages, unusual fonts, complex layers, and damaged files can reduce accuracy or processing speed.
Browser memory and device performance matter more for local tools than for upload-based services.

Local processing vs upload-based tools

Local tools keep routine website processing on your device, while upload-based tools send files to a remote server.
Upload-based services can move heavy work off your computer, but they add transfer time and require trusting a server with your files.
Use the API when you intentionally need server-side automation; use the website when you want private manual processing.

What to do if processing fails

Try a smaller file, a shorter page range, or one file at a time if the browser runs out of memory.
If a PDF is encrypted, damaged, or restricted, unlock or repair it first and then retry the workflow.
If the output looks wrong, check whether the source file uses scans, complex transparency, form fields, or unsupported embedded objects.

API automation

Use API docs to plan automated PDF workflows. If this exact website workflow is not exposed as an endpoint yet, you can still use available PDF API tools and Credits for supported operations.
