How to resize images
- Choose up to 30 images, each up to 50 MB: JPG, PNG, WebP, AVIF, GIF or BMP.
- Pick Pixels or Percent. For pixels, type a width, a height or both. For percent, type how big the result should be, such as 50 for half the size.
- Press Resize images, then download each one, or all of them together as a ZIP.
Pixels or percent?
Use pixels when something asks for an exact size: a profile picture of 400 × 400, a website banner 1,600 pixels wide, or a listing photo no wider than 1,200. Use percent to shrink a whole batch of photos by the same amount, whatever size each one starts at.
Keeping the shape
With Keep the shape ticked, a picture is never stretched. Type only a width and the height follows; type both and the image fits inside that box, so one side may come out smaller than the number you typed. Untick it to force both numbers exactly, which squashes or stretches the picture if its shape doesn’t match.
Format and quality
Same as the original keeps JPG as JPG, PNG as PNG and WebP as WebP. GIF and BMP come out as PNG, and AVIF as JPG. Choose JPG for photos and the smallest files, and PNG for screenshots, logos and anything with transparent areas. The quality setting, from 1 to 100, applies to JPG and WebP: lower numbers make smaller files with softer detail. Transparent areas turn white in a JPG, which can’t store transparency. WebP works in Safari too: Safari can’t make WebP itself, so there the page loads a WebP encoder of its own, on your device, the first time you need it.
Upright, and without the hidden details
Phones often store a photo sideways with a note saying which way is up; the resized copy is saved the right way up. Resizing makes a brand-new image, so the hidden details in the original, such as the camera, the date and the GPS location, aren’t carried over. Your original stays exactly as it was.
Making images larger
You can enlarge an image up to 16,384 pixels a side, but enlarging can’t add detail that wasn’t there, so small pictures blown up look soft. Phones have less memory than computers, and an image too big for one gets a clear message rather than a blank result. To make files smaller without changing their size in pixels, use the Image Compressor.
