What does an image resizer do?
It changes how many pixels a photo has. The whole picture stays in the frame, it just gets smaller or larger. That is the difference from cropping, which cuts pieces off the edges.
Most people resize to meet a limit: a form that wants a photo under 1000 px, a shop that asks for 2000 px product shots, or an email that bounces anything over a few megabytes. Type the size, check the preview and save.
How to resize a photo
- Add your photo. Choose it, drag it onto the box, or paste it from your clipboard.
- Pick the new size. Type a width or height, drag the scale slider, or tap a longest side like 1080 px.
- Choose a file type. JPG, PNG or WebP. The file size updates as you go.
- Download it. The button shows the exact size you will get.
Tips for a sharp result
- Keep the shape locked. With the link on, changing the width changes the height too, so faces never stretch.
- Go smaller, not bigger. Shrinking keeps detail. Enlarging past the original only adds blur.
- Use the longest side. Most sites ask for a maximum size. Setting the longest side fits both portrait and landscape photos.
- Pick JPG for photos. A JPG of a photo is often a fifth of the size of the same PNG.
- Keep PNG for cut-outs. JPG has no see-through areas, so a cut-out would get a white background.
- Need a different shape? Use the image cropper first, then resize.
Common sizes
Instagram posts. 1080 px wide. Square posts are 1080 × 1080 and portrait posts are 1080 × 1350.
Websites and blogs. 1600 to 2000 px on the longest side is plenty for a full-width image, and loads much faster than a phone photo straight off the camera.
Profile pictures. 400 to 800 px square. For a round one, the circle cropper does the crop and the size together.
Email and forms. Around 1200 px on the longest side, saved as JPG, keeps most photos under 300 KB.
Why resize before you share?
Smaller files send faster, upload faster and load faster. A page full of full-size phone photos can take seconds to appear on a slow connection. The same photos at 1600 px look identical on screen and weigh a tenth as much.
It also saves you from surprises. Many sites resize your upload for you, and not always well. Sending the size they expect means the photo looks the way you saw it here.
