Questions, answered.
Short version: it’s private, it’s free to start, and it works offline.
Do my files get uploaded?
No. Every PDF tool runs inside your browser using WebAssembly and workers; your documents never leave your device. The optional AI tools send only the extracted text you approve — never the file itself.
Is it really free?
Yes. All 49 local tools are free with generous limits (50 MB per file, 200 pages per task). Pro raises the limits, removes ads and unlocks larger batches.
Which formats are supported?
PDF in and out for most tools. The converter reads Word, Excel, PowerPoint, OpenDocument, RTF, EPUB, HTML, Markdown, text, CSV, HEIC and common images, and writes PDF, Word, Excel, PowerPoint, PNG, JPG and WebP — all typeset on your device.
Can I chain tools together?
Workflows let you run up to three tools in one pass — for example merge, watermark and number pages — and save the recipe for next time.
