About ToolRun

ToolRun is a collection of 45 free online tools for everyday tasks: merging and compressing PDFs, resizing and converting images, making passport photos, formatting JSON, generating passwords, and more. Every tool is free, needs no account, and has no usage limits.

Your files never leave your device

Most online tools upload your files to a server to process them. ToolRun doesn't. Every tool runs in your browser using JavaScript and WebAssembly, so your PDFs, photos, and text are processed on your own computer or phone. Nothing is uploaded, which makes ToolRun private by design, and often faster too, because there is no upload or download wait.

What's here

• PDF Tools: Merge, split, compress, and convert PDF files.
• Image Tools: Compress, resize, convert, and edit images.

How we keep tools accurate

Every tool page explains what the tool does, how it works, and its limits. If a tool gives you a wrong result or fails on a file, please let us know and we will fix it.
