How to resize an image online in three ways
Resize image changes the width and height of a photo in pixels. You can work on up to 30 photos in one go, and each one is resized the same way.
- A ready size: pick a social media or screen size from the list and the photo is made exactly that size.
- Exact pixels: type a width, a height, or both, up to 10,000 pixels.
- A percentage: 25%, 50%, 75%, 150% or 200% of the original.
Press Resize and download. One photo downloads on its own; several come together in a ZIP file. PNG files stay PNG, so see-through parts are kept. Other photos are saved as JPG.
WhatsApp DP size, Instagram post size and YouTube thumbnail size
These are the ready sizes in the list, in pixels:
- WhatsApp profile photo: 640 × 640
- Instagram post: 1080 × 1080 square, or 1080 × 1350 portrait
- Story, Reel or Status: 1080 × 1920
- YouTube thumbnail: 1280 × 720
- Facebook cover: 1640 × 624
- LinkedIn banner: 1584 × 396
- Full HD wallpaper: 1920 × 1080
With a ready size, the photo fills the whole frame. If its shape is different, the extra edges are trimmed evenly from both sides, so nothing is squashed. If an important part sits near the edge, crop it yourself first with Crop image and then resize.
Resize image to exact pixels without stretching
Forms and websites sometimes ask for a set size, such as 600 × 800 pixels. Here is how to get it right:
- Fill in only the width or only the height, and leave the other box empty. The other side is worked out for you, so the proportions stay the same.
- Fill in both boxes only when your photo already has that shape. If it doesn't, the picture will be stretched to fit.
- For an exact size with a different shape, crop first to the right shape, then type both numbers here.
Resize is not the same as KB
Making a photo smaller in pixels usually makes the file lighter too, but not to an exact number. If a form says under 50 KB or under 100 KB, use Photo to KB, which is built to hit a file size. Use this tool when the form, app or website talks about pixels, width or height.
Making a photo bigger, for example 200%, gives you more pixels but no extra detail. Small or blurry photos will still look soft when enlarged.
Common reasons to resize a picture, privately
Every photo is opened and resized by your own browser. Nothing is uploaded, so you can resize a whole folder of family photos or shop product pictures without sending them anywhere.
- An online shop or marketplace wants every product photo the same size, so the listing looks tidy. Resize the whole batch to one width in a single go.
- A school or office website slows down because of huge camera photos. Bringing them to 50% or to about 1200 pixels wide makes the pages load faster.
- Emailing many photos at once is easier when they are smaller in pixels, and they still look fine on a phone screen.
- A government or job form lists a width and height in pixels for the photo or signature. Type those numbers here, then check the KB limit separately.
- A banner for Facebook or LinkedIn looks cut off. Use the matching ready size so it fills the space as those sites expect.
