Resize images

Four ways to set the size

• Percentage: 50 % halves both sides, a quarter of the pixels. Good for making big phone photos manageable.
• Width: set the width in pixels, such as 1080 for Instagram or 1920 for a full-HD screen; the height follows.
• Height: the same, starting from the height.
• Fit in a box: the picture becomes as large as possible inside width × height without being cut or stretched, for example 800 × 800 for a store's product images.

The aspect ratio is always kept, so nothing is squashed. To change the shape, use Crop image first. The resized picture keeps its format (JPG stays JPG, PNG stays PNG with its transparency), and its name gets the new size, like photo-1080x810.jpg.

You can resize up to five pictures at once with the same settings.

On your device

Resizing happens in your browser; nothing is uploaded and there is no limit on how often you use it.

The new size is computed from your choice, rounding to whole pixels and never below 1 pixel. Each picture is decoded by your browser in a Web Worker, with phone orientation applied, and redrawn at the new size with high-quality smoothing, then saved in its original format (JPEG and WebP at quality 92). Enlarging works but can't add detail that wasn't there.
