Resize JPG, PNG, WebP and HEIC images to exact pixels or by percentage, in your browser. Batch resize, keep aspect ratio. Free, no sign-up, nothing uploaded.
Runs in your browser. Your files are never uploaded. How it works
Resize by
Resize Image changes the width and height of your images, right in your browser. Enter an exact size in pixels or a percentage, resize one image or a whole batch, and download the results one by one or in a ZIP file.
How to resize an image
Click Choose images or drop your files onto the page. The size fields are filled in from the first image.
Choose Pixels and enter a width and/or height, or choose Percentage and enter a scale such as 50%.
Click Resize. Each file shows its old and new size, and the file name gets the new dimensions, for example photo-1080x720.jpg.

With Keep aspect ratio on, an image with different proportions fits inside these sizes without being cropped or stretched. Turn it off to get exactly the size you enter.
Private by design
Your images are resized on your own device and never uploaded. Resized images do not keep EXIF data, so the GPS location and camera details are removed as well. See how it works.
Frequently asked questions
Are my images uploaded?
No. Images are resized by your browser and saved straight to your device. Nothing is sent to a server.
How does Keep aspect ratio work?
The width and height you enter act as a box. Each image is scaled to fit inside it without being stretched. Leave one field empty to set only the width or only the height.
Can I resize several images to the same size?
Yes. Add all of them and enter one width and height. With Keep aspect ratio on, each image fits the box in its own proportions; turn it off to force every image to exactly that size.
Can I make an image bigger?
Yes, but enlarging cannot add detail, so the result looks softer. For sharp results, start from the largest version of the image you have.
Does resizing reduce quality?
Making an image smaller keeps it sharp; the tool scales down in several steps to avoid jagged edges. JPG and WebP files are saved at 92% quality. PNG stays lossless.
What is the largest size I can create?
Up to 16,000 pixels per side and about 16 megapixels in total, the limit that works in every browser including iPhone Safari.
