How to Resize an Image to 100 KB
- 1
Add your photo
Drop a JPG, PNG, WebP or iPhone HEIC image on the box, paste it, or tap to pick it. The Under 100 KB limit is already chosen.

Set the size if your form asks
Keep the original width and height, or tap a preset such as 300 × 300 px. At 100 KB even a 1000 px wide photo usually stays sharp.

FAQ
Resize image to 100 KB: questions and answers
How do I reduce an image to 100 KB?
Add the image on this page: the Under 100 KB limit is already selected, so the tool finds the highest JPG quality that fits and shows the exact size before you download. Tap another limit or type your own if you need a different one.
How do I convert an image to 100 KB on my phone?
Open this page in Chrome or Safari, tap Select image and choose the photo from your gallery. Under 100 KB is already chosen, so just tap Download JPG. Nothing is uploaded and there is nothing to install.
Why did my image get smaller in pixels to reach 100 KB?
If the image is very large or detailed, even the lowest sensible quality can't fit under 100 KB at that width and height. The tool then scales it down just enough to fit and tells you the new size. Picking a smaller size first, such as 600 px wide, keeps more quality.
Is my photo uploaded to a server?
No. The image is resized inside your web browser on your own device, so 0 bytes are uploaded and nothing is stored. It even works offline once the page has loaded.
