Image Resizer

Resize your images to an exact size, a percentage, or a ready-made preset for Instagram, Facebook, YouTube and more — right in your browser.

About Image Resizer

Image Resizer changes the pixel dimensions of JPG, PNG, WebP, GIF and SVG files — pick a curated preset for Instagram, Facebook, X, LinkedIn, YouTube, Pinterest or a website hero image, type an exact width and height, or scale by a percentage. Presets that don't match your source's aspect ratio can crop to fill the frame or shrink to fit inside it with padding, and an upscale guard keeps a small source from being stretched into a blurry, oversized file. Every file is resized locally in your browser using the same high-quality resampling browsers use natively — nothing is ever uploaded. Add several files at once and resize them all with the same settings, then download them individually or together as a .zip.

FAQ

Will resizing reduce image quality?: Resizing itself uses high-quality resampling, the same the browser uses natively. If you also change the output format to JPG or WebP, a quality slider lets you tune the size-vs-quality tradeoff.
What's the difference between Cover and Contain?: Cover crops the image to fill the target size exactly, with no empty space. Contain shrinks the whole image to fit inside the target size, adding padding around it if the aspect ratio doesn't match.
Will this enlarge a small image?: Only if you turn off the upscale guard. By default, a target size larger than your source is scaled back down so the result is never stretched or blurry.
Are my files uploaded anywhere?: No. Resizing runs entirely in your browser — your files never leave your device.
Is there a file size limit?: Each file can be up to 25MB, and up to 20 files per batch, to keep things reliable on mobile browsers.
