How to Compress a Photo to 20KB

Compressing a photo or signature scan to 20KB is straightforward with this free tool. Follow these steps:

  1. Upload your image: Drag and drop or click to select your JPG, PNG, WebP, or GIF file. The image is processed entirely in your browser.
  2. Target is pre-set to 20 KB: The compressor is already configured for 20KB (20,480 bytes, since 1 KB = 1,024 bytes). By default it outputs a universally accepted JPG, or you can toggle Preserve original format.
  3. Click Compress: The tool reduces your photo to 20KB or less using smart quality and dimension reduction.
  4. Download: Save the 20KB compressed image directly to your device.

Tip: For 20KB compression, starting with a photo that has a plain background (like a white background portrait or black-ink signature on white paper) gives the best clarity at very small file sizes.

Frequently Asked Questions

How do I compress a photo to 20KB without losing quality?

Upload your photo above. The target is pre-set to 20KB (20,480 bytes). Click Compress and download. At 20KB, some quality or dimension reduction is expected, but the tool preserves maximum clarity under the 20KB ceiling.

Can I compress a PNG or WebP to 20KB?

Yes. The tool accepts PNG, JPG, WebP, and GIF. By default, files are encoded as JPG (with white fill for transparent areas) to easily reach the strict 20KB limit, or you can enable “Preserve original format” if you need to keep the original format.

Is my photo sent to any server?

No. All compression is done locally in your browser. Your image never leaves your device.
