About Image Resizer

Resize any image to exact pixel dimensions in your browser. Choose from four fit modes — Contain (letterbox with transparency), Cover (crop and fill), Stretch (distort to exact size), or Pad (letterbox with a custom fill colour). Download the result as JPEG, PNG or WebP. Single mode adds a draggable crop; batch mode resizes many files with the same settings. All processing happens locally in your browser using the Canvas API.

Does resizing upload my image?

No. Everything runs in your browser using the Canvas API. Your file never leaves your device.

What fit modes are available?

Contain (letterbox), Cover (crop and fill), Stretch (distort to exact size), and Pad (letterbox with a solid fill colour).

Will locking aspect ratio change my target dimensions?

Yes — when the lock is on, changing width recalculates height and vice versa, preserving the original aspect ratio.
