Image Resizer
Resize images to exact dimensions or by percentage.
The image is resized by your own browser and never sent anywhere, which the site enforces with a Content-Security-Policy that permits connections only back to its own origin.
Upload limits are usually written in pixels rather than megabytes: a 1600-pixel-wide header, a 512-pixel avatar, a forum that rejects anything taller than 2000. This resizer takes a JPEG, PNG or WebP file and produces the dimensions you ask for, either by typing a width or a height or by scaling to a percentage of the original.
More about Image Resizer
The aspect ratio is locked by default, so filling in one dimension works out the other and nothing comes back stretched. Unlock it only when you genuinely want a different shape. The original size, the target size and the file size before and after all stay on screen while you work, and the result sits beside the original so you can check the detail that matters before you download it.
All of it happens on your own device. The file is read, resized and re-encoded in your browser and is never sent to a server, so a large photo costs nothing but a moment of local processing. You can keep the format you started with or save to JPEG, PNG or WebP, whichever suits where the image is going.
- Set an exact width or height in pixels, or scale the image by percentage.
- Keeps the aspect ratio locked by default, so filling in one dimension sets the other.
- Shows the original size, the new size, and the file size before and after.
- Accepts JPEG, PNG and WebP files up to 25 MB and 40 megapixels.
- Writes JPEG, PNG or WebP, with WebP offered only when your browser can encode it.
- Respects the orientation recorded by the camera, so portrait photos stay upright.
- Drops metadata such as GPS location and camera details when it re-encodes.
How to use it
- 1Choose a JPEG, PNG or WebP image, or drag one onto the drop zone.
- 2Type the width or the height you need, or drag the scale slider to work in percent.
- 3Leave the aspect ratio locked unless you deliberately want a different shape.
- 4Pick an output format, and a quality setting if you are saving to JPEG or WebP.
- 5Check the new dimensions against the original, then download the resized image.
Questions
Are my images uploaded to a server?
No, they are resized by your own browser and never leave your device. The page is served with a Content-Security-Policy that permits connections only back to this site, so it has nowhere to send them.
Will resizing stretch my photo?
Not while the aspect ratio is locked, which is the default, because typing one dimension recalculates the other. Unlock it only when you want a different shape, and expect some distortion.
Can I make an image bigger than the original?
No, the output is capped at the longest side of the image you started with. Enlarging only invents pixels, so a larger original is the honest fix.
What is the largest image I can resize?
Up to 25 MB, and up to 40 megapixels. Anything above that is refused from the file header before it is decoded, because decoding an image that large can exhaust memory and crash the tab.
Does the resized file keep its EXIF data?
No, the file is rebuilt from decoded pixels, so GPS coordinates, camera model and timestamps are not carried across. The recorded orientation is applied to those pixels, so the photo still comes out the right way up.
