Resize images online
Change the width and height of your photos in pixels or by percentage. See the original size of every image, resize many at once, and download them one by one or as a ZIP. Your photos are resized inside your browser and never uploaded.
Everything runs on your device. Nothing you add or type is sent to any server.
How to use it
- 01
Drop your images into the box above, or tap it to choose photos. The list shows each image's original size.
- 02
Choose Pixels and type a width or height, or choose Percentage and enter a value such as 50%. Keep the aspect ratio locked so the photo does not look stretched.
- 03
Press Resize, check the new size of each file, then download them one by one or all together as a ZIP.
Why resize a photo
Online application forms often ask for a photo or signature with fixed pixel dimensions, and an upload is refused when it does not match. Websites and presentations also load faster with images sized for where they are shown. Always follow the exact numbers given in the form or platform you are using.
Making a photo smaller in pixels also makes the file smaller. If you need a smaller file without changing the dimensions, use the Compress Image tool instead.
Pixels or percentage
Pixels is best when you have a target size. With the aspect ratio locked, type only the width and the height follows, so faces and text keep their shape. If you fill both boxes, each photo is fitted inside that box without stretching. Unlock the ratio only when you really need an exact width and height, because the picture will be squeezed.
Percentage is quick for batches of photos with different sizes: 50% halves the width and height of every image. Enlarging a small photo is possible, but it cannot add detail that was never captured, so it will look soft.
Format and privacy
JPG, PNG and WebP images keep their own format unless you choose another; GIF, BMP and other formats are saved as PNG. Transparent areas turn white in JPG. Everything runs on your device, so you can resize ID photos and personal pictures without sending them anywhere.
Frequently asked questions
Will resizing reduce quality?
Making a photo smaller keeps it sharp. JPG and WebP are saved at high quality. Enlarging beyond the original makes it softer.
Can I resize several photos at once?
Yes. Add as many as you like, each up to 50 MB, and download them together as a ZIP file.
Why does my resized image have a different height than I typed?
With the aspect ratio locked, the image is fitted inside the box you entered so it is not stretched. Unlock it to force both numbers.
Does it work with iPhone HEIC photos?
Only in browsers that can open HEIC, mainly Safari on Apple devices. Elsewhere you will see a message that the photo could not be read; convert it first with our HEIC to JPG tool.
