About SabinPDF
SabinPDF is a free collection of document tools that run entirely in your web browser. There's no software to install, no account to create, and no file upload to a remote server — everything from converting a page of text into a PDF to merging a stack of contracts happens locally, on your own device, using JavaScript running in the tab you already have open.
We built it because most "PDF tool" websites quietly route your files through a server somewhere, which is unnecessary for the vast majority of everyday tasks and adds a real privacy trade-off for something as simple as signing a form or splitting a scanned document. Modern browsers are capable enough to do this work directly, so SabinPDF does exactly that.

Frequently asked questions
- Is SabinPDF really free?
- Yes. All tools are free to use, with no sign-up. The site may show ads to help cover hosting costs.
- Do you store or see my files?
- No. Every tool processes files locally in your browser. SabinPDF has no server-side file storage, so we never receive or see the content of anything you convert, edit, or sign.
- Does it work on my phone?
- Yes — SabinPDF is designed to work comfortably on both desktop and mobile browsers, including touch-based signing.
- Why didn't my "Fill PDF" find any fields?
- Fill PDF only works with PDFs that already contain real, fillable form fields. If a PDF is just a flat scanned image or has no form fields, use the PDF Editor tool to add text instead.
