OCR: make a scanned PDF searchable
Tesseract OCR compiled to WebAssembly recognizes the text of each scanned page and embeds an invisible text layer — your scan never leaves the device. Free and unlimited.
This tool runs entirely in your browser. Your file is never uploaded.
Perguntas frequentes
Is OCR really free? Most sites charge for it.
Yes. OCR runs on your own device using the open-source Tesseract engine compiled to WebAssembly, so it costs us nothing to run — and costs you nothing.
Which languages are supported?
v1 ships English and Simplified Chinese recognition models. More languages are added based on demand.
Are my files uploaded to a server?
No. All local tools process your file inside your browser using WebAssembly. You can verify this in the Network tab of your browser's developer tools.
Do I need a subscription?
No. Local tools are free without limits. AI features use one-time credit packs whose balance never expires.
