What the free plan actually gives you
Around thirty PDF operations — merge, split, compress, OCR, protect, convert to and from Office formats — with no file count, no daily cap and no watermark. It is funded by ads on the site rather than by limiting the tool.
The offline Windows installer is the part most people miss: it runs the same toolbox locally, so confidential documents never leave the machine. For anything under NDA, that is the version to use.
Where it breaks
- Web interface carries display ads
- Desktop app is Windows-only
- No cloud storage integration
What we would use instead
If the limits above are a problem, the closest free substitutes are CloudConvert and TinyPNG. They are not identical — each one trades something different — but all of them let you finish a job without paying.

Questions people actually ask
Is there really no limit?
No file count or daily cap has been observed in normal use. Very large files are limited by your browser memory.
Can I use it offline?
Yes, the Windows installer runs the full toolbox locally with no upload.
Are uploaded files kept?
Web uploads are processed and deleted after a short window. For sensitive documents, use the offline version.
