About the Image Compressor
Large image files slow down websites, fill up storage and bounce back from email attachment limits. Compression shrinks the file size by removing data the eye barely notices, so your images load faster while still looking good. This tool compresses images right in your browser and lets you download the smaller version.
Nothing is uploaded — the compression is done locally, so even private or unpublished images stay on your device.

Tips & good to know
- Aim for the smallest size where the image still looks good — the last bit of quality often isn't worth the extra kilobytes.
- Photographs compress far more than flat graphics or text-heavy images.
- Resize oversized images to the dimensions you actually display before compressing for the biggest savings.
Frequently asked questions
- Will compression ruin my image quality?
- Not if you choose a sensible level. You can preview the result and dial the quality up or down until you're happy.
- Is my image uploaded to a server?
- No. Compression runs locally in your browser and your image is never transmitted.
- How much smaller will the file be?
- It depends on the image, but photos often shrink by 50–80% with little visible change.
