Image converter
Convert between JPG, PNG, WebP, and AVIF. Right in your browser. No uploads.
What this tool does
Different formats are good at different jobs. JPG is great for photos and terrible for logos. PNG keeps transparency and lossless quality but produces big files. WebP gives you JPG-like quality at half the size. AVIF goes further, at the cost of slightly worse browser support. A converter is the tool that lets you pick the right format for each context.
How to use it
- Upload your image.
- Pick the target format.
- Adjust quality (for lossy formats).
- Download the converted file.
Why it matters
Serving WebP or AVIF instead of JPG cuts your page weight in half without any visible difference. For ecommerce, marketing sites, or anywhere images dominate the page, this is one of the biggest single performance wins available.
Questions people actually ask.
Which format should I use for [thing]?
Photos on a modern site: WebP, with a JPG fallback for older browsers. Logos and graphics with text: PNG or SVG. Hero images where every kilobyte matters: AVIF. Email attachments: JPG, for compatibility.
Will I lose quality converting?
Depends. PNG to JPG loses transparency and adds compression artifacts. JPG to WebP at high quality is visually identical. AVIF to AVIF is lossless. Test before publishing.
Why are my converted PNGs so big?
PNG is lossless — it preserves every pixel exactly. Great for graphics with sharp edges; terrible for photos. If you converted a photo from JPG to PNG, the PNG will be 5-10x bigger with no visible benefit.
