How to Compress Images Without Losing Quality
Practical tips for shrinking JPG, PNG, and WebP files while keeping them sharp — for faster websites and smaller uploads.
Image compression sounds technical, but the goal is simple: make the file smaller without your eyes noticing. Done right, you can cut file sizes by 60–80% and nobody can tell the difference.
Pick the right format
- JPG — best for photos and anything with gradients.
- PNG — best for logos, icons, screenshots with sharp edges, or anything needing transparency.
- WebP — modern format that beats both, usually 25–35% smaller than JPG at the same quality. Supported everywhere except very old browsers.
The 80% rule
For JPG and WebP, quality settings between 75 and 85 give you huge file size savings with no visible loss. Below 60, artifacts start creeping in — blocky skies, blurry text.
Try our Image Compressor: upload, drag the quality slider, and download the result.
PNG is different
PNG uses lossless compression, so there is no "quality" slider — you save space by reducing the color palette or converting to WebP. If your PNG is a photo, convert it to JPG or WebP for a much bigger win.
When to resize instead
If your image is 4000 pixels wide but you're displaying it at 800, you're wasting 96% of the file. Use Image Resizer to match the display size — usually a bigger saving than compression alone.
Fast checklist
- Resize to the display size first.
- Then compress at 80% quality.
- Serve WebP if your platform supports it.
- Add descriptive alt text for accessibility and SEO.
