How to resize an image online

1. 1

   Add your photos

   Drag photos onto the page or choose them with the button, on a phone straight from your photo library. The tool accepts JPG, PNG, WebP and HEIC from iPhone.

2. 2

   Enter the new size

   Choose Width, Height, Width and height, Longest side or Percentage and type a value, or click a quick preset. Below the fields you see right away what size the photo will get.

3. 3

   Check the dimensions

   Each photo shows its new size. The Do not enlarge smaller photos option is on by default, so photos smaller than the size you entered keep their original dimensions.

4. 4

   Download your photos

   Click Save photos. One photo downloads on its own, several in one ZIP. The new size is added to the name, for example vacation-1920x1440.jpg.

Is the photo for Instagram?

For Instagram you don't need to type a size. Instagram stores photos up to 1080 px wide and crops ratios outside 1.91:1 to 3:4 when you upload. On the Crop for Instagram page you prepare the photo at 3:4 or 4:5 and place the crop yourself.

How to resize an image to exact pixels

For an exact size such as 1080 × 1080 or 600 × 600 px, choose Width and height and enter both values. Then decide what happens when the shape doesn't match. Keep aspect ratio fits the whole photo inside, so one side may come out smaller. Fill and crop trims the overflowing edges evenly to reach your size, and Stretch reaches it by distorting the photo. If the original is smaller than that size, turn off Do not enlarge smaller photos first. The result is capped at 16 MP.

Fill and crop keeps the center of the photo. If the subject isn't in the middle, use Crop image instead, where you move the crop area yourself. When the site also sets a limit in KB, shrink the file afterwards with Compress image.

Which pixel size to choose

A phone photo is usually several thousand pixels wide, far more than a screen needs. A photo with a 1920 px long side looks as sharp as the original on a Full HD screen, so the Full HD preset is enough for a website, an email or slides.

For an online store or a gallery, images of the same width work well, for example 1080 px. Select all the photos, choose Width and enter 1080, and the height follows on its own. For marketplaces, check their help first: eBay wants at least 500 px on the longest side and recommends about 1600 px, while Etsy recommends at least 2000 px.

How to resize a photo on Windows and Mac

On Windows, open the photo in Paint, press Ctrl + W to open Resize and skew (in Windows 10, the Resize button on the Home tab) and enter the new size in pixels or percent. Then save the photo under a new name so you keep the original.

On a Mac, open the photo in Preview and choose Tools > Adjust Size. Enter the width and height and keep Scale proportionally on. To resize several images at once, open them in one window, select them in the sidebar and choose Tools > Adjust Size.

Paint handles one photo at a time. This page resizes a whole batch at once and works the same on Windows, Mac and phones, with nothing to install.

How to resize a photo on iPhone and Android

On an iPhone with iOS 26 or later, open the image in the Preview app, tap the More button and then Adjust Size. Choose the options you want and tap Done.

The Gallery app on Galaxy phones can shrink a photo while editing, through the three-dot menu, but only to a few preset percentages, not to an exact number of pixels, and it can't enlarge.

If you need an exact pixel size or many photos at once, open this page in Safari or Chrome on your phone and pick the photos from your library. iPhone HEIC photos are accepted and saved as JPG.

Pixels, inches and printing

On a screen, a photo has only a size in pixels. Inches appear only when you print, and they depend on how many pixels go into one inch, a value called DPI.

If a photo lab or print shop wants 300 DPI, a 4 × 6 inch print needs 1200 × 1800 px and an 8.5 × 11 inch page needs 2550 × 3300 px. Multiply the inches by the DPI to get the pixels. If your size is in centimeters, divide it by 2.54 first.

Don't enlarge a photo before printing. Enlarging adds pixels but not detail, so the print won't be any sharper. Send the original full-resolution photo to print instead.
