Resize an image
Give photos exact pixel dimensions, scale them by percentage or crop them to a set shape, one image or a whole batch at a time.
Add one or more images.
or drop files here
Cropping works on one image at a time. The first image is shown.
Files never leave your device. Everything runs in your browser.
How to use it
- Add your images with "Choose files" or by dropping them onto the page.
- Under "What to do", keep "Resize" or switch to "Crop".
- To resize, enter a "Width" and "Height", switch "Resize by" to "Percentage", or tap one of the "Quick sizes". To crop, pick a "Crop shape" and position the frame.
- Choose a format under "Save as", then click "Resize" or "Crop".
- Click "Download", or "Download all (ZIP)" for several images.
What it does
Exact pixels or a percentage
Type a width and height with "Keep aspect ratio" on by default, or scale everything by a percentage.
Quick sizes without stretching
1080 × 1080, 1920 × 1080, 1280 × 720 and 800 × 600 give exactly that size; if the shape differs, the edges are trimmed evenly instead of the picture being stretched.
Crop to a shape
Crop with a free frame or a fixed ratio: 1:1, 4:3, 3:2, 16:9 or 9:16.
Choose the output format
Keep the original format, or save as JPG, PNG or WebP. With "Same as original", HEIC and AVIF photos are saved as JPG, and GIF and BMP images as PNG.
Batch resizing
Resize many images in one go and download them as a ZIP. Cropping works on one image at a time.
Opens common formats
Works with JPG, PNG, WebP, GIF (first frame), BMP, HEIC, and AVIF where supported, all on your own device.
Good to know
Resize by pixels when a website or form asks for specific dimensions. With "Keep aspect ratio" on, you only need one number and the other follows, so the picture keeps its proportions. Percentage is quicker when you simply want everything smaller, for example 50% to halve both sides of a batch of photos.
Quick sizes cover common targets: 1080 × 1080 for square social media posts, 1920 × 1080 and 1280 × 720 for widescreen slides and video thumbnails, and 800 × 600 for simple web images. Because they give exactly that size, a 4:3 photo set to 1080 × 1080 loses an even strip from each side rather than being squashed. To choose exactly which part stays, use "Crop" with the 1:1 shape instead, and if the file also needs to be small, run it through Compress image afterwards.
Questions and answers
How do I resize an image without stretching it?
Leave "Keep aspect ratio" on and enter just the width or the height. Quick sizes don't stretch either: when the photo's shape differs, they trim the edges evenly.
How do I make a photo square?
Choose the 1080 × 1080 quick size, or switch to "Crop" and pick 1:1 so you can decide which part of the picture to keep.
Can I resize several images at once?
Yes. Add all the images, set the size once and click "Resize". Cropping is the exception, since it works on one image at a time.
Can I resize iPhone HEIC photos?
Yes. HEIC photos open directly, and under "Save as" you can choose JPG, PNG or WebP for the resized copies.
Will resizing reduce the file size?
Making an image smaller in pixels usually makes the file smaller too. For a bigger reduction, use Compress image afterwards.
Are my images uploaded?
No. Resizing and cropping happen in your browser on your device, and the images are not sent to a server.
