Get any file into the format you need
Drop a file, pick what you want, download. Images, audio, video, and PDF, all handled in your browser.
Convert files without uploading them
Most converters send your files to a server, process them there, and send them back. FormatMill works differently: the conversion runs in your own browser, so your photos, documents, and videos never leave your device. That is faster for everyday files and private by default.
Are my files uploaded anywhere?
No. Every tool runs inside your browser using code that loads onto your device. Your files are read, converted, and saved locally, and never sent to us or any server.
Is FormatMill free?
Yes. Every tool is free with no sign-up, no watermark, and no limit on how many files you convert. The site is supported by ads.
What can I convert?
Images (JPG, PNG, WebP, AVIF, HEIC, and more), video and audio, PDFs, documents, and spreadsheets. You can also compress, resize, crop, and merge files.
Do I need to install anything?
No. It runs in any modern browser on Windows, Mac, Linux, Android, or iOS, with nothing to download or install.
