How the image resizer works

Step 1

Upload your image

Drag a JPG, PNG or WebP file into the drop zone, or click to browse your device.

Step 2

Pick a preset or set dimensions

Choose a ready-made size like Instagram Square or HD, or type a custom width and height. With the aspect ratio locked, the other value updates automatically.

Step 3

Compare and download

Resize the image, compare the before and after side by side, and download the result in JPG, PNG or WebP format.

Frequently asked questions

Will resizing stretch my image?

Only if the aspect ratio is unlocked and you set a width and height that don't match the original proportions. Keep the lock enabled to avoid distortion.

Can I make an image larger?

Yes, though enlarging beyond the original resolution can make the image look softer, since no new detail is being added.

Is there a size limit?

Uploaded files can be up to 25 MB, and you can set target dimensions up to 10,000 pixels per side.

What do the presets do?

Each preset fills in the exact width and height used by a common platform, such as an Instagram Square post or a YouTube thumbnail. Pick "Custom" at any time to enter your own dimensions.
