Percentage or pixels
Percentage scales every image by the same amount, so a batch of different sizes stays in proportion. 50% halves the width and height, which makes a photo about a quarter of the file size.
Pixels sets an exact size. Enter only a width or only a height and the other side follows the image's shape. Enter both and the image fits inside that box.
Untick Keep aspect ratio to stretch the image to exactly the width and height you entered.

Quality
Making an image smaller keeps it sharp, because the tool uses your browser's high-quality scaling. Making it bigger can't add detail, so an enlarged small image looks soft. JPGs are saved at quality 92, which is close to the original.
Privacy
Resizing runs in your browser. Your images are not uploaded to a server.
Frequently asked questions
How do I resize an image without losing quality?
Make it smaller and keep the aspect ratio. Shrinking keeps images sharp. To cut the file size as well, use Compress image.
Can I resize many photos at once?
Yes. Add them all, choose a percentage or a size and click Convert. Download them together as a ZIP.
How do I resize to an exact width and height?
Set Resize by to Pixels, enter both numbers and untick Keep aspect ratio. The picture stretches if its shape is different.
Can I make an image bigger?
Yes. Choose 150% or 200%, or enter a larger size in pixels. The image can't gain detail, so it may look soft.
Does resizing change the format?
No. JPG stays JPG, PNG stays PNG and WebP stays WebP. To change the format, use a converter such as PNG to JPG.
Is location data removed?
Yes, by default. Camera details and GPS location are removed. Set Metadata to Keep to leave them in.
