About Image Format Converter
The Image Converter transforms images between all popular formats including PNG, JPEG, WebP, AVIF, and GIF. Whether you need transparent PNGs, compressed JPEGs, or modern WebP files for web optimization, this tool handles it all.
WebP and AVIF formats offer superior compression compared to traditional formats, reducing file sizes by 25-50% while maintaining quality. Convert your images to these modern formats for faster website loading and better user experience.

Frequently Asked Questions
What is the best image format for websites?
WebP offers the best balance of quality and file size for web use, with 25-35% smaller files than JPEG. Use PNG when you need transparency. AVIF is even better but has less browser support currently.
How do I convert PNG to JPG without losing quality?
Set the JPEG quality to 90-95% for near-lossless conversion. Note that JPEG doesn't support transparency, so transparent areas will become white (or you can choose a background color).
Can I convert WebP back to PNG or JPG?
Yes! Select WebP images and choose PNG or JPEG as the output format. PNG will preserve quality perfectly (lossless), while JPEG will be smaller but with slight quality loss.
What happens to image transparency when converting?
PNG and WebP preserve transparency. When converting to JPEG (which doesn't support transparency), transparent areas become white by default. You can optionally specify a different background color.
Is AVIF better than WebP?
AVIF typically offers 20% better compression than WebP at similar quality. However, WebP has broader browser support. Use AVIF with WebP fallbacks for best results.
