Is FreePDFToolbox really free?
Yes. All 50 tools are free, with no accounts, no watermarks and no limits on pages or file size (beyond what your device can handle).
Are my files uploaded anywhere?
No. Every tool processes files locally in your browser. There is no server to receive them. You can verify this in your browser's developer tools — no network request contains your file.
Do I need to create an account?
No. There is no account system at all.
Do the tools work offline?
Once the page and its assets have loaded, yes — processing is purely client-side. The first visit needs a connection to fetch the page; afterward, everything runs on your device.
What file sizes are supported?
There is no artificial limit. Practical limits depend on your browser and device memory — most browsers handle files up to roughly 200 MB comfortably. Very large files are processed in chunks.
Which browsers work?
Current versions of Chrome, Edge, Firefox and Safari, on desktop and mobile. See Browsers Supported for details.
Why is OCR slow?
OCR recognition is CPU-intensive and runs on your device (no cloud). Higher resolutions are more accurate but slower. A 10-page scan typically takes a minute or two.
Why are some features limited?
Several tools document technical limits honestly — for example, visual redaction does not remove underlying text, and PDF/A conversion is not ISO-certified. The limitations are about what client-side libraries can genuinely do in a browser. We prefer honest limitations over fake capabilities.
Can I use these tools for business?
Yes. The MIT/Apache-licensed libraries permit commercial use, and the tools themselves are free for personal and commercial use.
