Frequently asked questions

What file formats can I convert?

Images (180+ formats including PNG, JPEG, WebP, AVIF, HEIC), audio (MP3, WAV, FLAC, OGG, AAC, and more), video (MP4, WebM, MKV, MOV, GIF), and documents (DOCX, EPUB, HTML, Markdown, ODT, RTF).

Are my files uploaded to a server?

No. ImageMagick, FFmpeg, and Pandoc run as WebAssembly in your browser. Files never leave your device.

Can I convert video to MP3?

Yes — extract audio from MP4, MKV, WebM, MOV, and other video formats. You can also convert audio to video with a static background.

Why is the first conversion slow?

WASM engines download once (~15–56 MB depending on category) and are cached by your browser afterward.
