Reduce any image to 100 KB for free in your browser. 100 KB is a sweet spot for fast-loading web images and email attachments — small enough to load quickly, large enough to look sharp. Upload a JPEG, PNG, or WebP and download the compressed result instantly.
100 KB suits most inline web images, email attachments, and form uploads that allow up to 100 KB. A typical photo at 100 KB looks indistinguishable from the original at normal screen sizes, making it a great default for blogs and websites.
Drag and drop or click to select a JPEG, PNG, or WebP image from your device.
The tool automatically compresses your image to 100 KB or less. No settings needed.
Use the starting-quality slider to push as close to the limit as possible for the best quality, then re-compress.
Click download to save the compressed image, ready to upload anywhere.
