Frequently Asked Questions

Find answers to your questions

What formats can I convert to?
You can convert to JPEG, PNG, WebP, and AVIF. For input, we also support GIF, BMP, TIFF, and more.
What's the difference between WebP and AVIF?
WebP is a Google-developed format that's 25-35% smaller than JPEG. AVIF is a newer format, 30-50% smaller than JPEG with better quality, but encoding is slower.
How does the quality setting work?
PNG is lossless so there's no quality setting. JPEG, WebP, and AVIF support 1-100% quality — higher means better quality but larger files.
Are images sent to a server?
No. All image processing happens 100% in your browser. WebAssembly-based codecs run locally, so images are never sent to a server.
Can I convert multiple images at once?
Yes, you can drag & drop multiple images or select multiple files at once. All images are converted to the same format.
