What it does
A photo straight from a phone is often 4,000 pixels wide or more: too big for a form, a website or an email. This tool makes a new copy at the size you need:
By width or height: give one side and the other follows, so nothing is stretched.
By width and height: fit the image inside a box, or turn off Keep proportions to get an exact size.
By percentage: 50% makes each side half as long.
Don’t enlarge, on by default, keeps an image that is already small enough at its own size.
Save as keeps the format or changes it to JPG, PNG or WebP. GIF and BMP images come out as PNG, and AVIF as WebP.
Each file’s card shows its new size in pixels and in bytes, so you can check the result before you save it.
How to use it
Drop your images on the box, paste them, or select Choose files. Select “Try a sample” to see two example images.
Choose how to resize under Resize by, and enter the size. Every image is resized at once, and again when you change a setting.
Select Download on a card to save one image, or Download all to save them together in a ZIP file.
Press Ctrl+Enter (⌘+Enter on a Mac) to run every image again, or Esc to stop the ones still working.
Good to know
Each image can be up to 50 MB and 50 megapixels, and you can add up to 20 images at once.
The new size can be at most 16,384 pixels on a side and 50 megapixels in all.
The tool reads JPG, PNG, WebP, AVIF, GIF and BMP still images. Animated images and HEIC photos aren’t supported yet.
Transparent areas stay transparent in PNG and WebP. JPG has no transparency, so they turn white.
Files are named after the original with the new size added, such as photo-1920x1440.jpg.
Privacy
Your images are processed on your device: the tool runs in your browser and doesn’t upload them. The new image is made from the pixels alone, so camera details and location data from the original are always removed.
Frequently asked questions
How do I keep the proportions?
Resize by Width or Height and the other side follows, so the picture keeps its shape. With Width and height, Keep proportions fits the image inside the box you give, so one side may come out smaller than you asked. Turn Keep proportions off to get exactly that width and height; the picture is then stretched or squeezed to fit.
Can making an image bigger make it sharper?
No. An enlarged image has more pixels, but no new detail: the extra pixels are worked out from the ones already there, so it looks softer. That's why Don't enlarge is on by default. An image that is already within the size you ask for keeps its size, and its card says so.
Does a smaller image mean a smaller file?
Usually. Fewer pixels take less space: halving the width and height leaves a quarter of the pixels, so the file usually gets much smaller. The format matters too: JPG and WebP are small for photos, PNG suits screenshots and logos. Under More options, Save as changes the format and Quality trades size against detail for JPG and WebP.
Why was my photo sideways before, and upright now?
Phones often save a photo as the sensor saw it and add a note saying which way to turn it. Some apps and websites ignore that note and show the photo sideways. This tool turns the pixels the way the note says, so the resized image is upright everywhere.
Are my images uploaded? What happens to location data?
No. Your images are resized by your browser, on your device, and they aren't sent anywhere. The new image is made from the pixels alone, so camera details, the date and any GPS location in the original are left out. When a JPG had a location, its card says Location data removed.
