Resize an Image
Set an exact width and height in pixels and download the resized image. Keep the aspect ratio locked so nothing gets stretched — all in your browser, nothing uploaded.
How to use
Upload an image and its current size appears. Type a new width or height; with 'Keep aspect ratio' on, the other side updates automatically so the picture isn't distorted.
Choose PNG (lossless), JPEG or WebP and download. Resizing runs entirely on your device, so there's no upload wait and no watermark.
FAQ
Will resizing distort my image?
Not if you keep the aspect ratio locked — the tool adjusts the other dimension for you. Unlock it only when you deliberately need a non-proportional size.
Can I make an image larger?
Yes, but enlarging beyond the original resolution can look soft or pixelated, since there's no extra detail to add. Downscaling always stays crisp.
Is there a watermark or upload?
Neither. The resize happens in your browser with the Canvas API and the result downloads directly — no watermark, no server.
Which format should I pick?
PNG for graphics and transparency, JPEG for photos (smaller), WebP for the best balance. For extra savings, run it through the image compressor afterwards.
