Click Resize and download the image at the exact new dimensions, ready to upload anywhere.
Almost every place you upload an image expects a specific size. Instagram wants a square, a YouTube thumbnail is 1280×720, a profile photo has a minimum, and a website hero needs exact pixels to look crisp. Upload the wrong dimensions and the platform crops off the important part, stretches the picture, or rejects it outright. The straight-from-camera photo is also usually far bigger than needed, which wastes bandwidth and slows pages. This resizer lets you set exact width and height, with an aspect-ratio lock so changing one dimension adjusts the other automatically and your image never comes out squashed. Built-in presets cover the common social and web sizes so you do not have to look them up. Everything runs in your browser using the Canvas API, so your image is never uploaded — and your original is untouched, so you can re-export at another size in seconds. No account, no watermark, no limit.

No. Resizing happens in your browser with the Canvas API, so your image never leaves your device.

Common ones like Instagram post (1080×1080), YouTube thumbnail (1280×720), X post (1200×675), and Facebook cover (1200×628).
Making an image smaller keeps it crisp. Enlarging it beyond its original size can look soft — for that, use the AI Image Upscaler.
