Resizing without losing sharpness

01

Pixel-exact control

Type the exact width, and optionally the height, that you need. Leave one field blank and the aspect ratio locks automatically, so nothing gets squashed unless you deliberately ask it to. This is the fastest way to hit a strict upload spec down to the pixel.

02

High-quality scaling

Resampling uses high-quality smoothing, so shrinking a large photo stays crisp and enlarging stays as clean as the source allows. The canvas interpolates neighboring pixels rather than dropping them, which keeps edges smooth instead of jagged when you scale down a detailed image.

03

Stretch or contain

Choose stretch to hit exact dimensions even if the shape changes, or contain to fit inside a box without distortion. Contain is ideal when a platform demands a maximum size but you still want the original proportions preserved intact.

04

How resizing works

Your image is drawn onto a fresh canvas at the target size, and every output pixel is computed from the source pixels around it. Because it happens in your browser on that canvas, the file never leaves your device and the preview is immediate.

05

Resize vs crop

Resize changes how many pixels the whole image spans while keeping all of the content. Crop instead removes content from the edges. If you need a specific pixel box and want to keep everything visible, resize is the right tool; to cut away borders, crop first.

How to resize an image

1

Upload your image

Drop in a PNG, JPG, WebP, or SVG, or click to browse and pick a file from your device.

2

Set the dimensions

Enter a width, and a height if you need an exact box. Choose stretch to force the size or contain to keep proportions.

3

Preview and download

Check the resized result against the original, then download the full-resolution file with one credit on a free account.

When you need an exact pixel size

Platform specs

Hit exact upload sizes for avatars, thumbnails, banners, and app icons without guesswork.

Faster pages

Shrink oversized photos so they load fast and lift your Core Web Vitals scores.

Email and docs

Downsize images to fit attachment limits and slot neatly into document layouts.

Consistent sets

Standardize a gallery to one width so every thumbnail lines up cleanly.

Or just ask

Describe the edit in your own words

Type what you want changed and the assistant does it on the canvas — useful when the edit is easier to say than to find.
