Compress image to 100KB
Compress image to 100KB for forms, profile photos, passport uploads, applications, and websites with strict image-size limits.
Use this page when an upload form says image under 100KB, maximum 100KB, or photo should be less than 100KB.
Set 100KB and compress
Upload the file, choose KB, enter 100, then download the result when compression finishes in your browser.
Match the upload wording
100KB, 100 KB, maximum 100KB, and under 100KB usually describe the same upload limit.
Choose the exact number from the form first, then use format or resize controls only when the portal still rejects the file.

Questions people ask
Can I compress an image to 100KB?
Yes. Upload a JPG, PNG, WebP, or GIF image, set the target to 100KB, and let the browser-based compressor work toward that limit.
Which format works best for 100KB images?
JPG is usually best for photos. PNG can be better for screenshots, signatures, and graphics with sharp edges or transparency.
What if the image is still above 100KB?
Try reducing dimensions as well as quality. Many upload portals combine a KB limit with maximum width and height rules.
