About FileToaster
A free file converter that does the work on your own device, so your files never have to leave it.
What FileToaster is
FileToaster converts everyday files: photos and images, PDFs, audio and archives. You can turn iPhone HEIC photos into JPGs, combine images into a PDF, pull the audio out of a video, or open a RAR file on a Mac.
What makes it different is where the conversion happens. On most converter sites you upload your file, a server converts it, and you download the result. On FileToaster the converter itself comes to you: it loads into your web browser and processes your files right there, on your phone or computer. Your files are never uploaded.
There’s no account to create, no daily allowance and no file-count limit. The only practical limit is your device’s memory.
Who makes it
FileToaster is a small independent website. It isn’t part of a larger software company, and it isn’t a free trial for a paid product. It was built out of wanting a converter you could trust with your own files.
Why it’s free
Banner ads pay for FileToaster. You’ll see clearly labeled ad spaces on the pages, never on top of the converter.
We don’t use popups, pop-unders, full-screen ads or app-install prompts. Ads stay in their marked spaces, each labeled “Advertisement”, and the converter works the same whether you look at them or not. The buttons that convert and download your files are always inside the converter box itself.
Ads come from Google AdSense, which may use cookies. Visitors in the EEA, the UK and Switzerland are asked for consent first. The privacy policy and cookie page explain exactly what’s involved.
Why your files are never uploaded
The files people convert are often private: photos of family, scanned IDs, contracts, voice messages. Sending them to a stranger’s server just to change a file format is a risk you shouldn’t have to take.
Modern browsers are powerful enough to do the work locally, using JavaScript and WebAssembly. So that’s how FileToaster is built: the page and the converter code download to your browser, your file is processed on your device, and the result is saved straight back to it.
This is a claim about your file data only. Like any website, FileToaster’s pages still load their code, ads and privacy-friendly, cookieless analytics over the internet. But nothing you convert is ever sent to us or anyone else. How it works explains the technical side and shows you how to check this yourself in a couple of minutes.
What FileToaster doesn’t do
- No downloading from links. We don’t fetch files from URLs, and we never download videos from YouTube or other sites. You convert files that are already on your device.
- No OCR yet. PDF to Text works on PDFs that contain real text. Scanned documents need optical character recognition, which isn’t available yet.
- No password-protected archives yet. Encrypted ZIP, RAR and 7z files can’t be opened for now.
