Image
Compressor.
Compress images to an exact size — 20 KB, 50 KB, 100 KB or any number — or by quality. Resize, convert to WebP, compare before and after, and download them all as a ZIP. Nothing is uploaded.
Why compress images
Images are usually the heaviest part of a web page and the most common reason a form rejects an upload. This image compressor shrinks JPEG, PNG, WebP and AVIF files in your browser — either to an exact file size such as 50 KB or 100 KB, or to the quality you choose — and can resize and convert them at the same time.
How to compress an image to 50 KB, 100 KB or 20 KB
- Add your photo (drag it in, tap to choose, or paste it).
- Keep Target size selected and tap 20 KB, 50 KB, 100 KB — or type your own number.
- The tool tries quality levels until the file fits, and shrinks the dimensions slightly only if it must.
- Tap Compare to check it still looks right, then Download.
This is handy for online applications that limit photo and signature size — for example government job forms, exam registrations, passport and visa portals — and for email attachments.
Which format should you use?
| Format | Best for | Notes |
|---|---|---|
| WebP | Most website images | Usually 25–35% smaller than JPEG at the same look. Supported by all modern browsers. |
| JPEG | Photos, forms, email | Accepted everywhere. Use it when a form asks for JPG. |
| PNG | Logos, screenshots, transparency | Lossless, so files stay larger. In target-size mode a PNG photo is saved as JPEG. |
| AVIF | Next-gen websites | Often smaller than WebP, but older software may not open it. |
Good settings for the web
- Quality 70–80% keeps photos sharp while cutting most of the size.
- Resize to the size you show. A blog image rarely needs more than 1200–1600 px wide.
- Use WebP for websites unless a platform asks for JPEG or PNG.
- Keep the original file in case you need a bigger version later.

Image compressor FAQ.
Are my images uploaded to a server?
No. Compression happens in your browser on your own device. Your images are never uploaded or stored, and location data (EXIF) is removed from the result.
How do I compress a photo to exactly 50 KB or 100 KB?
Choose Target size, tap 50 KB or 100 KB (or type any number), and add your photo. The tool finds the highest quality that fits under that size.
Will compression make my images blurry?
At 70–80% quality most photos look the same to the eye. Use the Compare slider to check before you download.
Why did my PNG not get much smaller?
PNG is lossless, so detail cannot be thrown away. Convert it to WebP or JPEG for a much smaller file, unless you need transparency.
Can I compress many images at once?
Yes. Add up to 50 images, then download them one by one or all together as a ZIP file.
Does image compression help SEO?
Yes, indirectly. Smaller images make pages load faster, which improves user experience and Core Web Vitals.
