About Convertur
Convertur is a free set of file converters and utility tools that run in your browser. Your files stay on your device. They don't wait in an upload queue or sit on a conversion server.
Why it exists
People often need a converter for personal files: a tax PDF, a camera roll, a voice note, a contact export, or a work spreadsheet. Convertur does the processing on your device, so a simple task never means handing that file to us.
You also skip the usual hassle. There is no account, no install, and no hard upload limit. What you can process depends on your browser, your device memory, and how complex the file is.
What you can do
Convert images and camera RAW files. Edit and reorder PDFs. Prepare documents, convert audio and video, open or create archives, move data between formats, and use developer tools. Some tools use WebAssembly or machine learning models that run in the browser. They download the engine first, then do the work locally.
Start with the complete tool list, or drop a file on the home page and Convertur will suggest a tool that fits.
How local processing works
Code running in the page reads the file you choose. The converted result is created in that same page for you to download. Large conversion engines and model data may come from Convertur or a content delivery service, but your source file is not sent with those requests. Our Privacy Policy covers this in detail.
Who publishes Convertur
Convertur publishes the tools, guides, glossary and blog on this site as one brand. Articles and guides are written and reviewed by the Convertur team and credited to Convertur rather than to individual bylines.
You can reach us at hello@sajam.dev or through the contact page. Convertur is also on X, and is built and run by SAJAM.
How we build and check tools
Our methodology explains which engines each kind of tool uses, how we test results, and how often pages are reviewed. Every tool page shows the date its copy was last updated. The changelog lists what has changed on the site, and the disclaimer covers the limits of browser-based conversion.
Have a look around
Start at the home page, browse the tools, or send a message if a format is missing or a result needs attention.
