What to know before compressing to 20KB

Small file limits are easier to pass when the image is already cropped and sized correctly.

20KB Target Is Preloaded:

Use the exact file-size goal instead of trying random quality levels.

Good for Signatures and IDs:

20KB works well for small signature images, profile photos, and simple form uploads.

Dimension Controls:

Resize pixels before compression if a portal asks for both dimensions and file size.

Related File Sizes:

If 20KB is too small or too large for your rule, try 15KB, 100KB, or 200KB.

Privacy First:

The tool runs locally in your browser, so document images stay on your device.
