Frequently asked questions
Is this ocr pdf tool really free?+
Yes — every FoldPDF tool is free with no file limits, watermarks, or sign-up. Processing runs on your own device, so it costs us nothing to serve.
Are my files uploaded to a server?+
No. Files are processed entirely inside your browser using WebAssembly. You can verify with your browser's developer tools that no file data is transmitted.
How does ocr pdf work?+
Recognise text inside scanned pages with Tesseract (WASM) and overlay an invisible, searchable text layer — the scan itself is never uploaded.
