Image Resizer
Resize images to any dimensions while preserving aspect ratio. Runs in your browser.
Frequently Asked Questions
Does this upload my image anywhere?
No. Resizing happens entirely in your browser using the Canvas API. Your image is never sent to a server.
Will resizing reduce quality?
Shrinking is lossless-ish — the browser uses bilinear interpolation. Upscaling always loses quality. For best results, only downsize.
What's the max image size supported?
Browsers typically handle images up to ~16384x16384 pixels. Very large images may be slow or fail on low-memory devices.
