About this tool

Resize images to custom dimensions and compress them online for free. Reduce file size without losing quality. This tool runs entirely in your browser — no file upload, no account required, and no data is ever sent to a server. The conversion uses the browser's built-in Canvas API for accurate, lossless pixel manipulation.

  • ✅ Free to use, no sign-up required
  • ✅ Files never leave your device
  • ✅ Instant conversion
  • ✅ Works on any browser and device

How it works

Your file is loaded into an HTML Canvas element at its original dimensions. The Canvas API reads and re-encodes the pixel data in the target format. The result is served as a download directly from your browser — no round-trip to a server.
