How to compress an image to 100 KB
- Add your image. JPG, PNG, WebP, HEIC and more. Several at once is fine.
- We do the maths. Each image is compressed to the best quality that still fits under 100 KB.
- Download. Check the final size next to each file, then download.
When do you need an image under 100 KB?
Common uses include job portals, university and exam applications, visa forms and profile pictures that require images under 100 KB. Instead of guessing a quality setting and trying again, this page searches for the best quality that meets the limit for you.
For photos, JPG usually gives the best result at small sizes. If your image has transparency, choose WebP as the output format to keep it.
Frequently asked questions
Will my image be exactly 100 KB?
It will be just under 100 KB. We pick the highest quality that fits, so the file is usually close to the limit without going over.
What if the image is still too big?
If even low quality isn’t enough, we gradually reduce the pixel dimensions until it fits. Very large photos may end up smaller in width and height.
Are my images uploaded to a server?
No. Every image is processed inside your browser using WebAssembly. Nothing is sent over the internet, which also makes it fast and safe for private photos.
Is it really free? Are there limits?
Yes. It’s free with no sign-up, no watermark and no daily limit. Your own device does the work, so there is no server cost per image.
