Does image compression affect quality?
Our compression tool uses advanced algorithms to reduce file size while maintaining visual quality. For JPEG and WebP, you can adjust the quality from 1-100% to balance file size and quality. PNG compression is lossless but limited.
What image formats are supported?
We support JPG, PNG, WebP, and GIF formats. Maximum file size is 50MB. You can also convert to different formats during compression - choose between JPEG, PNG, or WebP output.
How much can I reduce image file size?
Depending on the original format and quality, reductions of 50-80% are common. JPEG images compress the most, while PNG images see less reduction. Our tool shows you exactly how much you saved.
Can I resize images while compressing?
Yes! Use the "Max Width" option to resize your image to a specific width while compressing. This helps reduce file size even more for web use. You can also keep original dimensions.

What's the best compression settings for web images?
