Compress Image to 100KB
Quickly reduce image size to 100KB or below while keeping the best possible clarity.
Step 1
What does the website require?
Paste the image requirements exactly as the website shows them.
Step 2
Upload your image
JPG, PNG or WebP, straight from your device.
Private browser processing — your image is processed on your device and is not uploaded to our servers.
Add an image to enable processing.
Results appear here with before/after previews and a validation check for every requirement you set.
Quick presets
Jump to a page with the file-size limit already set, then upload your own image.
Passport and signature requirements differ by country and portal, so UploadFit does not assume dimensions — paste or enter the exact ones your form asks for.
When you need 100KB
100 KB is a comfortable ceiling for document scans, marketplace listings and website images — small enough for slow connections, large enough to stay sharp.
How it works
- 01The 100 KB maximum is preloaded and fully editable.
- 02Upload the image you want to shrink.
- 03Compare the before and after previews, then download.
