Compress Image to 100 KB
Shrink a photo to 100 KB or less, automatically.
🔒 Everything above runs on your device — your file is never uploaded anywhere.
Compress Image to 100 KB brings a JPG or PNG down to 100 kilobytes or less automatically. Free, private and browser-based.
100 KB is a common limit for profile pictures, document photos and product images on portals and marketplaces. It is generous enough that most photographs stay clear, so the tool usually only lowers JPG quality slightly and keeps the original dimensions.
The tool searches for the highest JPG quality that fits under the limit, and only reduces the dimensions if quality alone is not enough. The result is always a JPG, and the whole process runs in your browser, so the photo is not uploaded.

Frequently asked questions
How do I reduce an image to 100 KB?+
Upload it here. The tool automatically picks the highest quality that keeps the file at or under 100 KB, and shrinks the dimensions only if it has to.
Will my photo keep its original size in pixels?+
Usually yes. The tool lowers quality first and only shrinks the dimensions if quality alone cannot reach 100 KB.
Is my photo uploaded?+
No. The image is processed in your browser and never sent to a server.
Will the picture look worse?+
Some quality is lost, as with any compression. The smaller the target, the more visible it is. At this size most photos still look clean.
