About

PDFSahl is a set of free tools for everyday work with PDF files: merging, splitting, editing, signing, filling in forms, adding text and page numbers, and a good deal more. There is no sign-up, no subscription, no daily limit and no watermark on your files.

Why "Sahl"?

Sahl (سهل) is the Arabic word for "easy". That is the whole idea: open the page, choose your file, get the result. No account to create, no plan to pick, no program to install.

Your files stay on your device

Every tool runs inside your web browser. When you choose a file, it is read and changed on your own computer or phone, and the finished file is handed straight back to you. Your files are never uploaded to us or to anyone else, which is why this site can be free without asking you to trust it with your documents.

Arabic, done properly

Most PDF tools treat Arabic as an afterthought: letters come out unjoined, lines read backwards, and numbers in an Arabic sentence end up reversed. Every tool here that writes text is built and tested for Arabic from the start, joined and from the right, with Arabic and English mixed on one line in the order you read them.

What it cannot do

We would rather tell you the limits than have you find them. The tools cannot read text from a scanned page, cannot compress a file, and do not convert to or from Word. A visual signature is not a certified digital signature. Where a tool has a limit, its own page says so.

Built on open source

This site stands on the work of open-source projects: pdf-lib (MIT) for building PDF files, PDFium (Apache-2.0 and BSD) through @embedpdf/pdfium (MIT) for drawing pages and editing text, HarfBuzz (MIT) for shaping Arabic, fontkit (MIT), bidi-js (MIT), fflate (MIT), Astro, React and Tailwind CSS (all MIT).

The fonts are Noto Sans, Noto Serif, Noto Naskh Arabic, Noto Sans Arabic, Noto Kufi Arabic, Amiri, Cairo, Arimo, Tinos, Cousine, Caveat, Dancing Script and Aref Ruqaa, all under the SIL Open Font License 1.1. Our thanks to everyone who made them.
