How to resize an image
Two ways to resize
Exact size sets the width and height you type, in pixels. Max side keeps the proportions and scales the image so its longest edge fits your number, up to 8,192 pixels.
Example: a 3×4 photo
For a document photo, first crop close to a 3:4 frame with the image cropper, then resize with exact size to a 3:4 pixel size such as 300 × 400.
Stays on your device
The work happens in your browser, so the image is not uploaded to our servers. Files up to 15 MB; download the result as PNG, JPG or WebP.
Frequently asked questions
Are my images uploaded?
No. Resizing uses the Canvas API in your browser. We only verify you are a real visitor for rate limits.
What is “max side” mode?
Your image scales proportionally so its longest edge matches the larger of the width and height values you enter.
What is the size limit?
Up to 15 MB per file on the web. Output sides are capped at 8,192 pixels.
