What it is
PDF is a free set of PDF tools from LittleOrMore. Every tool runs inside your browser tab: your document is read from your device, processed by code running in the tab, and saved back to your device. There is no account, no upload and no server-side processing.

LittleOrMore does not need your document to perform the operation.
How it works
The site is static files — HTML, CSS, JavaScript and WebAssembly. Open-source engines (Mozilla PDF.js, pdf-lib, qpdf, pdfcpu and Tesseract OCR) are served from this site and load only when a tool needs them. After first use, the tools you've used keep working offline.
Known limitations
Browser memory
Everything happens in your browser's memory, so very large documents can be slow or too big for a phone. You'll be warned about large files, and you can always cancel.
XFA forms
Dynamic XFA forms (an old Adobe format) are not supported. Standard PDF forms are.
OCR accuracy
OCR supports English, Tamil, Hindi, Malayalam and Telugu. Accuracy depends on the scan; handwriting is recognized poorly and tables or multi-column pages can come out in an imperfect order. Searchable text is positioned closely, not exactly.
Offline OCR
After first use the tools work offline. OCR works offline only for languages whose data your browser has already downloaded.
Redaction
Redaction is permanent: each page with a redaction is turned into an image, so its text can no longer be selected or searched. Always review the result before sharing.
Signatures
Sign PDF places a visual (electronic) signature, not a cryptographic certificate signature. Signature check reports what can be verified on this device; it does not confirm the signer's identity, certificate trust, revocation or legal validity.
Compression
Compression is lossless: it reduces unnecessary structure without changing how pages look. Files that are already efficient, or mostly photos, may not get smaller — you'll be told when that happens.
Text in other scripts
Added text (page numbers, watermarks, stamps, headers, notes and typed signatures) supports Latin, Tamil, Devanagari, Malayalam and Telugu. Other scripts are refused rather than printed incorrectly.
