📐 Image Resizer — Custom KB
Resize images by dimensions OR by exact file size (1KB-1000KB). All processing in your browser.
How the Custom KB Resizer Works
Our unique KB resizer tries different quality levels until it reaches your exact target file size. Enter any size from 1KB to 1000KB and the tool will iteratively compress until it matches — perfect for WhatsApp, email attachments, or website optimization.
Formula: Quality = Target KB ÷ Original KB → adjusted in real-time for precision.
