About Convert

Convert is a free, privacy-first file conversion tool. It converts video, audio, and image files between common formats — quickly, and without the privacy trade-offs of most online converters.

How it works

Whenever possible, Convert does the work inside your browser using WebAssembly (a compiled build of FFmpeg). For small files this means your data never leaves your device: there is no upload, and therefore nothing for anyone to leak.

Larger files, and formats that need heavier processing, are handled by a sandboxed server pipeline over an encrypted connection. Those files are converted in isolation and deleted automatically right after the job finishes.

What you can convert

• Video — MP4, MOV, MKV, WEBM, and extracting audio to MP3, WAV, AAC, FLAC, M4A, OGG, Opus.
• Audio — convert between MP3, WAV, FLAC, AAC, M4A, OGG, Opus, and Apple Lossless (ALAC).
• Images — PNG, JPG, WEBP, BMP, GIF, TIFF, ICO, HEIC, plus SVG, EPS, RAW, and PSD sources.
• Animation — turn video clips into GIF or animated WebP.

Why it's free

Convert is supported by advertising, which lets us keep it free for everyone — no sign-up, no watermarks, no limits. See our Privacy Policy for how ads and cookies are handled.
