Which files can I convert?

Images (PNG, JPG, WebP, GIF, BMP, SVG, AVIF, ICO, HEIC), video (MOV, MP4, MKV, AVI, WebM, FLV, WMV, M4V, 3GP, MPG, TS, GIF), audio (MP3, WAV, OGG, M4A, FLAC, AAC, WMA, OPUS, AIFF), PDF (to and from JPG, PNG and WebP) and CAD (JPG, PNG and PDF to DXF).

Is it really private?

Yes. There is no upload step at all. Image conversion uses the Canvas API, video and audio use a WebAssembly build of FFmpeg, and PDF work uses PDF.js and pdf-lib. All of it executes on your own device.

Why does the first video or audio conversion take a moment?

The FFmpeg engine is about 31 MB and is downloaded the first time you use any video or audio converter. After that it is cached by your browser and conversions start immediately.

Is there a file size limit?

No enforced limit. Very large videos need a lot of memory, so extremely big files depend on your device. Files over about 600 MB show a warning.

Can I convert many files at once?

Yes. Almost every converter accepts multiple files. Image converters download the batch as a ZIP; video and audio converters give each file its own download button.

Lossless targets (PNG, WAV, FLAC) keep every bit. Lossy targets (JPG, WebP, MP3, MP4) give you a quality control. Video containers are remuxed with no re-encoding whenever possible.

Does it work on iPhone and Android?

Yes. The site is fully responsive and every converter works in mobile Safari and Chrome. HEIC to JPG is especially handy straight from an iPhone.

Do I need an account?

No. There is no account, no email, and no password. Open the page and start converting.

Yes. Every converter is free to use with no sign-up and no watermark. The site is supported by display advertising.

About

Why Super File Converter?

Most online converters upload your file to a server, make you wait in a queue, and cap the size unless you pay. We do none of that. The converter runs on your own machine, so it is as fast as your computer and as private as your hard drive.
