How to Compress Your Image to 20KB

If you are applying for a job, registering for an exam, or filling out a government form online, you often need to upload a passport-sized photograph or a scanned signature that is strictly under 20KB. Our free tool is built specifically for this purpose.

1. Upload Your Photo: Click the file upload button above and select the image you want to shrink from your device.
2. Adjust the Slider: To achieve a file size as small as 20KB, you will usually need a high compression rate. Move the slider to 85% or higher.
3. Process and Download: Click "Compress Image". The tool will process your file and provide a compressed version. Check the new file size—if it's still slightly over 20KB, simply upload it again and increase the compression percentage!

Why Was My File Rejected by an Online Portal?

Many web portals have strict file size limits because they process millions of applications and need to save server storage space. If your file is 21KB and the limit is 20KB, the system will automatically reject it. Our tool helps you bypass this frustration by accurately reducing the file data.

Tips for Getting the Best Results

• Crop First: If your photo has a lot of unnecessary white space or background, crop it on your phone or computer before uploading it here. Smaller physical dimensions naturally result in a smaller file size in KB.
• Use JPG Format: While we accept various formats, saving your image as a JPG is universally the best way to achieve tiny file sizes without completely ruining the image quality.

Is My Data Safe?

Absolutely. We know you are often uploading sensitive documents like ID photos or signatures. Your images are processed securely, are not stored permanently on our public servers, and are never shared with third parties.
