Reduce Image Size in KB
Resize, compress and convert images to meet exact KB-based upload requirements.
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.
Bring your own limit
Every portal words its rule differently — under 40 KB, between 10 and 60 KB, around 80 KB. Paste the sentence exactly as it appears and UploadFit works out the measurable parts.
How it works
- 01Paste the requirement text, or set the KB rule manually.
- 02Upload your image and let the bounded quality search do the work.
- 03Check the validation cards, then download.
