Frequently Asked Questions

What is the best format for website images?
WebP is currently the best format for web - 25-35% smaller than JPEG with the same quality. AVIF is even smaller but has limited browser support. Use our converter to convert existing images to WebP for faster loading websites.
Does AVIF work in all browsers?
AVIF is supported in Chrome, Edge, Firefox, and Opera. Safari added support in version 16.0. For maximum compatibility, WebP is a safer choice. Our converter automatically handles the conversion based on your selection.
Are my images uploaded to your server?
No! All conversion happens locally in your browser using HTML5 Canvas API. Your images never leave your device. No uploads, no storage, complete privacy.
What quality setting should I use?
85% is recommended for web (best balance of quality and size). 100% for maximum quality, 75% for social media, 60% for email. Use our quality presets for one-click optimal settings.
Does PNG to JPEG conversion preserve transparency?
