How to compress an image to 100KB
- Select or drop the image you want to bring under 100 KB.
- The tool automatically finds the highest quality that fits, reducing dimensions only if necessary.
- Review the preview, exact size and dimensions.
- Download the JPG. If the site also has pixel requirements, resize first with the image resizer.
Features
Guaranteed under 100 KB
The result is at most 100,000 bytes, so it passes limits defined with either 1,000 or 1,024 bytes per KB.
Keeps more detail
A 100 KB budget usually allows a sharp photo of around 1000–1600 pixels wide, good enough for profiles and portals.
Automatic, no guesswork
No need to try quality settings manually. The tool tests them for you and picks the best one.
Clear results
See the file size in KB and bytes, the dimensions, the quality used and how much smaller the file became.

Frequently asked questions
What if my image is already under 100 KB?
If it’s a JPG under the limit, the tool tells you and lets you keep the original, so it isn’t compressed a second time.
Why is the result a JPG?
JPG gives the smallest files for photos and is accepted by almost every upload form. PNG files of the same photo would be many times larger.
Will the image look worse?
Some detail is lost, but the tool uses the highest quality that fits. At 100 KB most photos still look clear on screen.
The tool says it couldn’t reach 100 KB. What can I do?
This is rare and usually happens with very detailed or noisy images. Crop away unneeded parts of the image, or resize it to smaller dimensions first, then try again.
Do you keep a copy of my image?
No. The image is processed in your browser and never uploaded.
What fits in 100 KB?
A typical phone photo is 2–5 MB and 12 megapixels. To reach 100 KB it has to lose most of that data. The tool first lowers the JPG quality, which removes fine detail you rarely notice, and only then reduces the pixel dimensions. For a normal photo you can expect a result around 1000–1400 pixels wide.
Documents with lots of white space and text compress very well, so scans can often stay at a higher resolution.
