Image Resizer
Drop a PNG, JPG, or WebP image below to resize it. Format stays the same — only the dimensions change.
Uploading a 4000px photo somewhere that only displays it at 400px wastes bandwidth and slows the page down. This resizes to exact dimensions while keeping your original file format intact.

Common questions
Does this upload my image anywhere?
No. Resizing happens entirely in your browser using the Canvas API. Your image never leaves your device.
Does resizing change my image's format?
No. The output keeps the same format as your source file (PNG, JPG, or WebP).
Can I resize without distorting the image?
Yes. Lock aspect ratio is on by default, so changing width automatically adjusts height to match, and vice versa.
