Resize an image to exact dimensions in your browser
Drop files here
or click to choose one or more — PNG, JPG, JPEG, WEBP, GIF, BMP
Processed entirely in your browser using a Web Worker. Nothing is uploaded.
How to use
- Select an image.
- Type the target width and height, in pixels.
- Click Resize Image.
- Download the resized result.
Accepted formats
JPG, PNG, WebP, GIF and BMP all work as input.
Features
- Set exact target width and height in pixels
- Works for both shrinking and enlarging an image
- PNG input stays PNG, keeping transparency intact
What happens to your file
EXIF metadata is not carried over to the resized output.
Known limitations
- Width and height are set independently — there's no aspect-ratio lock, so an unbalanced pair of values will stretch the image.
- Enlarging an image beyond its original size will look softer, since pixels are being interpolated, not invented.
- No preset sizes — every dimension is typed in manually.
Common use cases
- Fitting a photo to an exact pixel size required by a form
- Shrinking a large camera photo before uploading it
- Producing a consistent thumbnail size for a batch of images
Questions.
Is my file uploaded anywhere?
No. Resize Image runs entirely in your browser using a Web Worker — the file never leaves your device.
What file types does this accept?
Resize Image accepts PNG, JPG, JPEG, WEBP, GIF, BMP files.
Does resizing keep the original aspect ratio?
Not automatically — width and height are independent fields, so mismatched values will stretch the image. Calculate a proportional pair yourself if you want to keep the ratio.
Will enlarging a small image make it blurry?
Some softness is expected — the tool can't add detail that wasn't in the original, so scaling up trades sharpness for size.
