Using Resize Image
Change an image’s pixel width and height for a website, profile picture, or upload form. Resizing changes the number of pixels. It is different from cropping, which removes part of the scene, and from compression, which changes how the pixels are encoded.
Worked example
A 2400 × 1600 photograph has a 3:2 aspect ratio. Setting its width to 1200 and keeping that ratio gives a height of 800. If you instead force it to 1200 × 1200, the image can look stretched. Use Crop Image when you need a square composition rather than squeezing the whole photograph into a square.
What to check and what this tool cannot do
Enlarging a small image does not recover detail that was never present. Setting both width and height can change the aspect ratio. The local processing path caps requested dimensions at 10,000 pixels and remains subject to device memory and browser canvas limits. Metadata and animation may not be retained.
Getting a useful result
Check whether the destination asks for pixels, file size, or both. A smaller width often reduces file size, but a 1200-pixel image can still be too large in bytes. After resizing, inspect edges and text, then use compression if needed. Keep a full-resolution original for other uses.
Where processing happens
Developer and text tools process input in your browser. PDF and image tools may attempt local conversion and use server processing when local conversion is unavailable. Website requests and usage analytics are separate from the content you enter. Large files can exceed your device’s available memory. See how tools work and our privacy policy.
