Frequently Asked Questions
Does my file get uploaded to a server?
No. The converter runs entirely in your browser using FFmpeg compiled to WebAssembly. Your files are processed locally and never leave your device.
Which image formats can I convert?
Supported image formats include JPG, JPEG, PNG, GIF, BMP, WebP, ICO, TIFF, and more. Convert between any combination of these formats instantly.
Which audio and video formats are supported?
Audio: MP3, WAV, OGG, AAC, FLAC, M4A. Video: MP4, MOV, AVI, MKV, WebM, 3GP, FLV. You can convert any supported input format to any supported output format.
Can I convert multiple files at once?
Yes. Drop or select as many files as you like. You can set a different output format for each file individually before converting them all in one click.
Is there a file size limit?
There's no hard limit set by us, but very large files (several GB) may be slow depending on your device's available RAM and CPU. For video files over 500MB, a desktop app may be faster.
