Frequently asked questions
How do I compress an image to 100KB?
Choose the “100KB” preset and press Compress. The tool lowers the quality and, if needed, the pixel size step by step until the file is at or under 100KB.
Are my images uploaded?
No. Compression runs locally in your browser. Your images never leave your device.
Which formats are supported?
JPG, PNG and WebP. You can keep the original format or convert to JPG or WebP, which usually gives much smaller files than PNG.
Why is my PNG still large?
PNG is lossless, so it can't shrink as much as JPG. For photos, set the output format to JPG to reach small target sizes like 100KB more easily.
Will the image dimensions change?
Only if the target size can't be reached by lowering quality alone. In that case the image is scaled down a little until it fits.
