Image Compressor
Make JPG, PNG and WebP files dramatically smaller — with a simple quality slider, or by targeting an exact size like “under 100 KB”. Nothing is uploaded.
How to compress an image
- Add your imageDrop it above, browse for it, or paste from the clipboard.
- Choose how to compressEither set a quality level, or pick a target like “under 100 KB” and the tool finds the best quality that fits.
- Check & downloadA preview shows the compressed result and exactly how much was saved — then download it.
Why compress images?
Oversized images are the number one reason pages load slowly — and slow pages lose visitors and rank worse on Google. Compressing photos before uploading them to a website, shop, email or job application portal usually cuts their size by 60–90% with no visible difference.
This compressor works completely offline in your browser: compression starts immediately, there is no file-size cap imposed by a server, and your pictures are never sent anywhere.
FAQ
How do I compress an image to exactly 100 KB?
Pick “Under 100 KB” in the target size dropdown and press Compress. The tool tries multiple quality levels and keeps the highest one that stays under the limit — so you get the best possible look at that size.
Why isn’t my PNG getting smaller?
PNG is lossless and ignores quality settings, so it barely shrinks. For photos, compress to JPEG or WebP instead — that’s where the big savings are. Screenshots and logos may compress better with the resizer (fewer pixels) than recompression.
What quality should I use?
80% is a great default for photos. Use 60–70% for thumbnails and chat attachments, and 90%+ when quality really matters. Always check the preview before downloading.
Is WebP output worth it?
Yes — at the same visual quality, WebP is typically 20–30% smaller than JPEG. It works in every modern browser and app released in the last several years.
Are my images uploaded anywhere?
No. Everything happens in your browser. No server sees your files, and closing the tab erases them from memory.
