Resize an image to exact dimensions
Enter the width and height you were asked for, add your image, and download the resized copy. Nothing is uploaded and the original file on your device is untouched.
Resize to exact dimensions
Dimensions and file size are two different limits
Forms often state both: an image must be 200 by 230 pixels and under 50 KB, say. They are independent constraints — an image can satisfy one and fail the other — and they are fixed in that order. Resize first, then compress the resized copy, because compressing before resizing wastes quality on pixels that are about to be discarded.
This page handles the dimensions. Once the size is right, take the result to the target-size compressor and it will have far less work to do.
Keeping the proportions, or not
With the ratio locked, entering a width computes the height for you and the picture keeps its shape. That is what you want almost always.
Unlocking the ratio lets you force both numbers, which stretches the image. If a form demands exact dimensions that do not match your photo's proportions, the honest fix is to crop the photo to that shape first — a stretched face is obvious to whoever reviews it.
Enlarging does not add detail
You can enter dimensions larger than the original and the tool will produce them, but the extra pixels are interpolated from the ones already there. The image gets bigger and slightly softer; no new detail appears.
If a form specifies a minimum resolution that your photo does not meet, the real answer is a better original, not an upscale.
Questions people ask
Should I resize or compress first?
Resize first, always. Compressing then resizing throws away detail and then throws away the pixels that were holding what remained, giving a worse result at the same final size.
Can I resize in centimetres or inches?
Screens and upload forms work in pixels, so this tool does too. To convert, multiply by the dots per inch the form asks for — at 300 DPI, a 3.5 by 4.5 centimetre photo is about 413 by 531 pixels.
Does resizing reduce the file size as well?
Substantially, yes. Halving both dimensions leaves a quarter of the pixels, and the file usually shrinks by roughly the same proportion. Often resizing alone gets you under the limit.
Is the quality loss from resizing recoverable?
No. Keep your original file; the download is saved under a new name specifically so it cannot overwrite it.
