About ToolTan

ToolTan is a set of free online tools for images, PDFs, text, and everyday math. Every tool runs inside your web browser. Your files are never uploaded to a server.

Why we built it this way

Most tool sites do their work on a server. That costs the owner money, so they add limits: a cap on file size, a few free tasks a day, or a paywall. It also means your files leave your device. ToolTan takes a different path. The work happens on your own computer or phone, using the power the browser already has. That keeps your files private, and it lets us offer the tools with no upload, no file-size limit, and no sign-up.

What you can do here

You can convert an iPhone HEIC photo to JPG, shrink a picture to fit an upload form, merge or split a PDF, count words, clean up messy text, and work out everyday math. Each tool has its own page, so the site stays fast and simple. New tools are added over time.

Who makes it

ToolTan is run by a small independent team. We are not part of a big software company. If a tool is missing, or you find a bug, we would like to hear from you. The contact page has our email.
