This tool compresses an image down toward an exact target file size - like 20KB, 50KB, or 100KB - which is exactly what many government forms, exam applications, and upload portals require. Instead of manually adjusting quality settings and re-checking the file size repeatedly, you set the target and the tool works toward it directly.
Frequently asked questions
It aims to get as close as possible to your target size. Very small targets (like 20KB) require more aggressive compression and may not land on the exact byte count, but should be very close.
Smaller targets need heavier compression, which does reduce visible quality - if your form allows a slightly larger size, using the largest size permitted will generally preserve more visible detail.
It may reduce pixel dimensions as part of reaching a very small target size, since compression alone sometimes isn't enough - the tool balances quality and dimensions to hit your target as cleanly as possible.
