Live output size per format appears after you upload.
PNG, JPG, WebP, BMP, GIF, HEIC* — up to 20 images, 50MB each. *HEIC requires Safari.
Input formats: PNG, JPG/JPEG, WebP, BMP, and GIF (first frame). Output formats: PNG, JPG, WebP, and BMP. Any supported input can be converted to any supported output.
After you pick a file, the tool runs a live dry-encode in your browser for every output format and shows the resulting size next to each one. That lets you pick the smallest or highest-quality option without downloading first.
JPG and BMP do not support alpha channels, so transparent pixels have to be filled with a solid color. You can pick the fill color in the Advanced options sidebar (default is white).
Yes. Open Advanced options and change the width or height. Keep aspect ratio is on by default, so changing one dimension auto-updates the other. Max 16,384 px per side.
Quality applies to lossy formats (JPG and WebP) only. Lower values produce smaller files with more compression artifacts; 85 is a good default for photos. PNG and BMP are lossless and ignore quality.
