Image Resizer
Resize images in bulk by percentage or width and height, keep the aspect ratio or use social media sizes, with sharp results. Nothing is uploaded.
Drop files here, or
JPEG, PNG, WebP and more. Choose several at once, up to 50 MB each.
Or paste an image with Ctrl/⌘ + V
Files are never uploaded.
Every image keeps its own aspect ratio: it is resized by the side you typed last, and the other side follows (the value shown is for the first image).
Common sizes
Social media sizes
How to use
- Drop or choose one or more images.
- Choose “Percentage” and enter a value, or “Width and height” and enter a width or height. You can also click a common or social media size.
- With “Keep aspect ratio” checked, enter one side and the other follows. Uncheck it and enter both to choose between stretching and cropping to fill.
- Click “Download” on each image. The file name gets the new size, for example photo-1280x720.jpg.
FAQ
Are my images uploaded?
No. Resizing runs entirely in your browser; your images never leave your device.
What happens with images of different shapes?
With the aspect ratio kept, each image is resized by its own proportions. With a width of 1280, landscape and portrait photos both come out 1280 wide with their own heights, never distorted.
What does “Don’t enlarge smaller images” do?
Images smaller than the chosen size keep their size. Enlarging cannot add detail; it only makes the file bigger and blurrier, so this is on by default.
Does shrinking make images look worse?
The tool shrinks in several steps of half the size each, which keeps results sharp without jagged edges. JPEG and WebP are re-encoded at high quality (92) and keep their format. To make the files smaller still, run them through the Image Compressor.
Is EXIF data or the GPS location kept?
No. Re-encoding strips EXIF, GPS location and other metadata, after turning the photo upright according to its EXIF orientation. To view or remove EXIF data only, use the EXIF Viewer & Remover.
Why are social media sizes cropped?
They have a fixed aspect ratio, so to avoid distortion the middle of the picture is kept and the rest is trimmed (“Crop to fill”). To choose which part to keep, crop it with the Image Cropper first.
