Frequently asked questions
Are all PDFToolWorks tools really free?
Yes. All 12 tools are free, require no account, and do not reveal a payment step after processing.
Do my files leave my device?
No. Every tool on this site processes your files in your browser using standard web technology. Documents are not uploaded to our servers.
Will the tools work on a phone?
Yes, in modern mobile browsers. Very large or complex documents may exceed the memory available on some devices, so the tools state limits clearly instead of failing silently.
Can Compress PDF guarantee an exact file size?
No browser tool can honestly guarantee every target for every document. PDFToolWorks reports whether the target was reached and returns the best safe result when it was not.
