Resize Image scales photos and graphics to a size you choose, either in pixels or as a percentage of the original. You can keep the aspect ratio locked or set an exact width and height. Choose several files and they are all resized with the same settings.
The work happens in your browser, so the pictures are never uploaded. You can keep each image in its original format or save the results as JPG, PNG or WebP.
How to use Resize Image
- Choose one or more images, or drop them onto the box.
- Pick By pixels or By percent, then enter the size. Leave Keep aspect ratio on to avoid stretching.
- Choose an output format, or keep the original format.
- Select Resize images, then download each file or all of them as a ZIP.
Frequently asked questions
Are my images uploaded?
No. Resizing runs in your browser, so your images never leave your device.
How do I resize without stretching the picture?
Keep aspect ratio on and enter only a width or only a height. The other side is worked out for you. Turn it off if you need an exact width and height, and the picture will be stretched to fit.
Can I resize many images at once?
Yes. Choose or drop several files. They all get the same size setting, and you can download them together as a ZIP.
Does making an image bigger improve it?
No. Enlarging cannot add detail that was never there, so the picture will look soft. Resizing down is the safe direction.
Will the file size get smaller?
Usually, when you reduce the pixels of a JPG or WebP. PNG files can stay large, because PNG is lossless. To shrink a file without changing its size, use the Compress Image tool.
Is there a size limit?
The limit is your device memory. Sizes above 16,384 pixels on a side, or about 100 megapixels, are refused with a message instead of crashing the page.
Which formats can I open?
JPG, PNG, WebP, GIF and BMP. Animated GIFs become a single still image.
