Resize image to exact file size
Many government portals, job application forms and ID upload systems have strict file size limits. Use this tool to compress any photo to exactly 20KB, 30KB or 50KB with one click.
| Target size | Common use case | Format |
|---|---|---|
| 20KB | Passport photos, profile pictures, ID cards | JPG |
| 30KB | Application forms, college admissions, job portals | JPG |
| 50KB | UAN, e-district, government and visa forms | JPG |
| Custom | Any portal with a specific KB requirement | Any |
💡 Always use JPG format for photos — it gives the smallest file size at any quality level. Switch to PNG only if you need a transparent background.

Frequently asked questions
Can I resize an image to exactly 20KB online for free?
Yes — completely free with no signup required. Upload your image, select 20KB as the target, choose JPG format, and the tool compresses it to 20KB or under automatically. Works entirely in your browser.
Are my images uploaded to your server?
Never. All compression happens in your browser using HTML5 Canvas. Your images never leave your device. 100% private and secure.
Why is my image still over 20KB after compressing?
This can happen with PNG format — PNG is lossless and does not compress as efficiently as JPG. Switch to JPG format and try again. For very large images, the tool will also reduce the pixel dimensions to reach the target size.
Will the image quality be acceptable at 20KB?
At 20KB, some quality reduction is expected — especially for large photos. The tool retains as much visible quality as possible. For passport photos and ID uploads, 20KB is usually sufficient for the portal's face recognition system.
Can I enter a custom size like 25KB or 45KB?
Yes. Click the "Custom" button, type your target size between 5KB and 500KB, and the tool will compress to that exact size.
Is there a file size limit for uploading?
No server limit since everything runs in your browser. The only constraint is your device memory. Most devices handle photos of 20MB+ without issues.
