Examples
A one-page scan reading HELLO LOCAL 2026; select page 1 at 144 DPI.
Limitations
PDF up to 50 MiB; up to 20 selected pages, 8 megapixels per rendered page and 80 megapixels total; 144 or 200 DPI. Password-protected and unsupported PDFs fail explicitly.
English, French and Dutch models. Printed text works best; handwriting, low resolution, unusual layouts, skew and mixed languages can reduce accuracy. Confidence is an estimate, not a correctness guarantee.
Portable Tesseract 7 LSTM runs in an owned worker. Initial engine and selected models use about 4–11 MiB of downloads; no image/PDF content is sent with these asset requests. Stage timeout: three minutes.
Recognized text is bounded to 5 MiB; searchable PDF to 100 MiB. Text preview shows at most one million characters and confidence table shows the first 200 words; downloads retain complete bounded results.
Creates rasterized page visuals plus a searchable text layer. Original forms, links, annotations, bookmarks, attachments, and metadata are not retained. Unsupported graphics fail explicitly.
