βΉοΈ PNG is a lossless format, so lowering quality won't shrink the file much. Choose JPEG or WebP for real size savings.

How to Use the Image Compressor
Upload an image, then drag the quality slider to re-compress it in real time and see the estimated file size. Width and height stay exactly the same β only the file size changes β and you can download the result as JPEG, WebP, or PNG. Everything happens in your browser, so nothing is ever uploaded.

1. Why Compress Your Images
Larger images slow down page load times, which increases bounce rates and hurts search rankings β Google factors page speed (Core Web Vitals) directly into ranking. Compressing images is therefore essential for both SEO and user experience, and it also cuts mobile data usage and server bandwidth costs, keeping visitors on your site longer.

2. How to Choose a Quality Setting
Most photos look nearly identical at 75-85% quality while shrinking 40-70% in size. Product photography or print-bound images should stay at 90%+ , while thumbnails, backgrounds, and blog illustrations hold up fine at 60-75%. Use the live preview to drag the slider and see the size/quality trade-off before you decide.

3. JPEG vs WebP vs PNG for Compression
JPEG and WebP are lossy formats, so lowering quality meaningfully shrinks file size. WebP typically delivers 25-35% smaller files than JPEG at equivalent visual quality, making it the best choice when your goal is compression. PNG, on the other hand, is lossless β the quality slider barely affects it β so it only makes sense for logos or icons that need transparency. Pick WebP or JPEG to minimize size, and PNG only when you need an alpha channel.
No. Compression happens entirely in your browser using the Canvas API β neither the original file nor the compressed result is ever sent anywhere, so sensitive photos stay private.
Does this also resize the image dimensions?
No, width and height stay exactly as they were β only the compression quality changes to shrink file size. Use an image resizer alongside this tool if you also want to change the resolution.
Why doesn't lowering quality shrink my PNG much?
PNG is a lossless format, so the quality parameter has little effect on its pixel data. Convert to JPEG or WebP if you want a meaningfully smaller file.
Does it handle EXIF rotation correctly?
Yes, modern browsers automatically apply EXIF orientation so photos are compressed and previewed right-side up. Older browsers without this support may not rotate the image.
