How it works

Select a supported PDF of up to five pages.
Choose English and optional cleanup, then upload for OCR.
Download the UTF-8 text and review page order and recognition errors.

Each page is rendered locally inside the server worker at 144 DPI and recognized by Tesseract. The text file separates pages with form-feed markers. This also works on supported PDFs that already contain text, but OCR can introduce errors.

Supported documents and limitations

Columns, reading order, tables and punctuation may not be reconstructed correctly. Blank pages contribute no recognized words. Original formatting is not retained. English printed text only. Maximum 10 MiB, five PDF pages, four megapixels per rendered page and sixteen megapixels total. Encrypted, malformed and active-content PDFs are rejected. Handwriting, unusual layouts and poor scans can produce missing or incorrect words. Review the result; no accuracy percentage is promised.

Temporary server processing

Your file is uploaded only when you choose to convert. An isolated worker processes it without network access. Uploaded files expire after one hour; completed outputs expire one hour after completion. Failed, cancelled or deleted jobs become eligible for immediate cleanup. Service outages can delay physical deletion; a previously issued download link can remain valid briefly. Clear files to request early deletion. Downloads saved on your device remain there.

PDF processing is limited to 200 pages; HTML and reverse conversions have the stricter limits listed above. Complex files may reach time, memory or scratch limits sooner. No malware-free, perfect-fidelity or certified-accessibility claim is made.
