How to Compress Image to 20KB Without Losing Quality

Most people fail to get a clear image under 20KB because they compress incorrectly.

Follow these optimization tips:

✔ 1. Start With a Good-Quality Original Photo

If your original image is already low quality, further compression will make it blurry.

Ideal original size: 200KB – 1MB

✔ 2. Use JPG Format for Best Compression

PNG files are very large.
JPG compresses better while retaining clarity.

ToolsOnlineHub automatically handles this.

✔ 3. Use Plain Backgrounds

Solid backgrounds reduce file size significantly.

Best colors:

• White
• Blue
• Light Gray

Ideal for passport/photo uploads.

✔ 4. Avoid Screenshots

Screenshots add unnecessary pixels and sometimes blur the image.

Always upload the original photo.

✔ 5. Keep Dimensions Between 300px – 600p

Best clarity under 20KB is achieved with:

Passport photo: 300×400 px or 350×450 px
Signature: 140×60 px or 200×100 px

This ensures you stay under 20KB without distortion.
