Frequently Asked Questions
Does converting to JPG lose quality?▾
JPG is lossy, so some quality loss occurs. Use 90–100% quality to minimize it. PNG is lossless and preserves full quality.
Does WEBP support transparency?▾
Yes, WEBP supports transparency (alpha channel) like PNG, but at much smaller file sizes.
What is AVIF?▾
AVIF is a next-gen image format based on the AV1 video codec. It offers significantly better compression than WEBP and JPG while maintaining high quality. Chrome, Firefox, and Safari 16+ support it.
Can I make favicons with ICO?▾
Yes! The ICO converter creates a standard 32×32 favicon-ready .ico file. Larger images are automatically scaled down.
Why is AVIF greyed out?▾
AVIF canvas encoding requires Chrome 121 or newer. Other browsers don't yet support creating AVIF images from the Canvas API. All other formats work in every modern browser.
