File format reference
60 formats, one page each. Every page covers what the format stores, how widely it is supported, what it is good and bad at, and every conversion available in either direction.
Images formats
Convert your photos and graphics between PNG, JPG, WebP, AVIF, HEIC, TIFF and more. Your pictures never leave your computer, and there is nothing to install.
Video formats
Convert video between MP4, WebM, MOV, AVI, MKV and more. It happens on your own computer, so there is nothing to upload and no queue to wait in. Free to use.
Audio formats
Convert audio between MP3, WAV, FLAC, AAC, OGG, M4A and Opus. Every file is handled on your own computer and never uploaded anywhere. Free, with no sign-up.
Documents formats
Convert documents between PDF, DOCX, Markdown, HTML and text. Nothing is uploaded, which matters when the file is a contract or an invoice. Free to use.
Archives formats
Open and repack archives: ZIP, TAR, GZ, TGZ, 7Z and RAR. Everything is unpacked and rebuilt on your own computer, with nothing uploaded and nothing to install.
Data formats
Convert data between JSON, CSV, YAML, TOML, XML, TSV and NDJSON. Nothing is uploaded, so an export full of real customer data stays with you. Free to use.
Fonts formats
Convert fonts between TTF, OTF, WOFF and WOFF2 for the web. The font is rewritten on your own computer, so a licensed typeface is never uploaded.
