Compress Image to 20KB

How it works
Upload your image
Choose the photo, scan, or document image that must fit under the requested file-size ceiling.
Use the 20KB target
The workbench aims below the selected ceiling while processing the file in your browser.
Review before upload
Check the downloaded file size, dimensions, format, and visual clarity against the active portal instructions.
Frequently asked questions
Can every image reach 20KB?
Not always. Large or detailed images may need cropping or pixel resizing first. A smaller file is not useful if the subject or document text becomes unreadable.
Does the tool upload my image?
No. The image is processed in your browser and does not need to be sent to a server.
Does the target replace the portal's own rules?
No. Use this target only when it matches the current form instructions. File size, pixel dimensions, format, and content rules may all be checked separately.
