About this tool
The Image Resizer changes your photo or graphic to any width and height you need — perfect for social posts, thumbnails and web uploads. Lock the aspect ratio to avoid distortion, or use quick presets like 50% or 1080px wide. Everything runs in your browser with the Canvas API, so your images are never uploaded to a server.

Frequently Asked Questions
Will resizing reduce quality?
Shrinking an image usually looks sharp. Enlarging beyond the original size may look soft because new pixels are interpolated.
Are my images uploaded?
No. Resizing happens entirely in your browser — files never leave your device.
Can I keep the aspect ratio?
Yes. Turn on Lock aspect ratio and changing width automatically updates height (and vice versa).
