Why PDFGuy processes files in your browser
Most free PDF tools upload your document to a server, process it there, and send it back. PDFGuy works differently: every tool on this site runs entirely in your browser using JavaScript. Your files are never transmitted anywhere, which means faster results, no file size limits tied to server storage, and no privacy risk for sensitive documents like contracts, IDs, or financial statements.
Frequently asked questions
Is PDFGuy really free?
Yes. All tools on this site are free to use, with no sign-up, no watermarks, and no hidden limits on how many files you can process.
Are my files uploaded to a server?
No. Every tool processes your files locally in your browser. Files are never uploaded, stored, or seen by anyone else.
Is there a file size limit?
There's no artificial limit set by PDFGuy. The practical limit is your device's available memory, since processing happens on your own device rather than a remote server.
Do I need to install anything?
No. Everything runs directly in your web browser — no software, extension, or app download required.
