Compress image to 100 KB
Upload an image and get a JPEG under 100 KB. The tool keeps the highest quality that fits, and only makes the image smaller in pixels when quality alone is not enough.
What to expect
100 KB keeps noticeably more detail. Many photos fit with only a moderate reduction in pixel size, and simple images such as scanned text often fit at their full size.
How to compress image to 100 kb
- Upload a JPG, PNG or WebP image. The target is already set to 100 KB.
- The image is compressed straight away; the before and after sizes, pixel size and quality are shown.
- Download the JPEG, or pick another size if the portal allows more.
Frequently asked questions
How do I compress an image to 100 KB?
Upload it above. The target is already set to 100 KB, so the tool compresses the image straight away and shows the new size before you download it.
Will the image lose quality?
The tool keeps the highest JPEG quality that fits under 100 KB. If even medium quality does not fit, it reduces the pixel size step by step instead of making the image blocky.
What if the image cannot get under 100 KB?
You get the smallest version possible and a note that the target was not reached. This only happens with very small targets and very large images; choosing the next size up usually works.
Which formats can I use?
JPG, PNG and WebP images. The result is always a JPEG, which is the most compact format for photos; transparent areas become white.
Is my image uploaded?
No. Compression happens in your browser, so the image never leaves your device.
