Compress and review
Check dimensions, quality and actual bytes before downloading.
Prepare a small signature image
Crop excess blank space in the source first. At this budget, smaller dimensions may keep the strokes clearer than a heavily compressed large canvas. Inspect the edges and actual bytes. If the tool cannot meet the target or the output loses detail, start from a tighter source or use 50 KB if allowed.
In an Edge test, a synthetic 900 × 1200 PNG (3.31 MB) was exported as a JPEG using this preset’s automatic quality and size settings. The download was 19.29 KB at 347 × 463 px. The smaller dimensions leave less detail to zoom into.

Compress Image to 20KB questions
Short answers, then the practical details.
How does the 20 KB image target work?
The tool tests actual JPEG output bytes against 20 × 1024 bytes, adjusting quality and then dimensions when needed. It keeps the best quality found within the current dimensions and target. Review the result before submitting because a strict file-size limit can require visible loss of detail.
Will compressing an image to 20 KB change its dimensions?
Dimensions may decrease when JPEG quality alone cannot fit your 20 KB limit. The result displays the output width and height so you can compare them with a form’s minimum requirements. If the photo becomes too small or soft, choose a larger target or a less detailed source image.
Can I keep transparency in a 20 KB image?
This preset exports JPG, which does not support transparency, so transparent source areas become white. It accepts JPG, PNG and WebP inputs, but the downloaded format is JPEG. Use the general image compressor with PNG output if retaining alpha transparency matters more than the 20 KB target.
