How to compress an image

Upload your image (JPG, PNG, or WebP — up to 30 MB).
Adjust the quality slider (80% is usually invisible; 60% cuts file size by half).
Download the compressed version — file size shown before and after.

Why compress before using

A 12 MP phone photo is often 4-8 MB. Uploading to social media, texting, or emailing that raw file wastes bandwidth and slows loading. Our compressor uses MozJPEG and Squoosh algorithms — the same tech Google uses — to shrink files by 50-80% with no visible quality loss.

Pro tips

For photos, JPEG at 80% quality is usually the sweet spot — smaller than PNG, better than lower quality JPEG.
For UI screenshots and diagrams, use PNG or WebP lossless — JPEG artifacts hurt text.
WebP compresses 25-35% smaller than JPEG at equal quality — use it when your target platform supports it (most modern browsers).

Frequently asked questions

How much smaller will my file get?

Typically 50–80% smaller at quality 75. A 5 MB phone photo usually lands between 800 KB and 1.5 MB with no visible difference.

Will I see the quality loss?

At 80% quality, almost never. Below 60%, fine texture and sharp edges start showing artifacts. The sweet spot for photos is 70–85%.

Should I pick WebP or JPEG?

WebP compresses 25–35% smaller than JPEG at equal quality and every modern browser supports it. Choose JPEG only when the file must open on very old devices or software.
