Image Resizer

ImageOffline-ready

Image Resizer lets you set exact pixel dimensions for any JPEG, PNG, or WebP image directly in your browser. Lock the aspect ratio to scale proportionally, or set width and height independently. The resized image downloads instantly at the same file format as the input. Useful for social media sizing, thumbnail generation, and profile photo resizing. Runs entirely in your browser — no file is uploaded.

Your files and inputs stay in your browser — nothing is uploaded or stored.

For stability, images are capped at 16,384px per side and about 50 megapixels total (~50,000,000 pixels).
