Compress Image to 100KB Online Free
Compress an image to 100KB and download a JPG for a photo upload limit, with more room for detail than the smaller presets. See the final file size, dimensions and image before downloading.
JPG, PNG or WebP · Up to 20MB · JPEG output with a white background
Keep useful detail within a 100KB budget
This preset starts with a maximum side of 3,000 pixels and searches for the highest tested JPEG quality that fits. If necessary, it reduces the dimensions and searches again. A complex scene may need more reduction than a simple portrait.
Use a larger limit when it is available
A 100KB target gives compression more room than 20KB or 50KB. If the receiving service accepts larger images, the general image compressor lets you choose quality without forcing this byte limit.
A few things worth knowing
Does 100KB mean 100,000 or 102,400 bytes?
This tool uses the stricter decimal target of 100,000 bytes. It displays the actual byte count so you can compare it with the receiving service's rule.
Can I upload several files?
This preset processes one image at a time so you can inspect each result. Choose another file to repeat the process.
