Image resizer

How to resize an image

  1. Choose a photo or picture from your device. Its current width and height are filled in automatically.
  2. Type the new width or height in pixels.
  3. Pick a resize mode (see below) and the file format: PNG or JPG.
  4. Check the preview and press Download image. The original file on your device is not changed.

The three resize modes

Keep proportions (automatic). Change one side and the other follows, so the picture keeps its shape. Use this for most photos.

Exact size: crop the edges. The image fills the whole target size and the parts that do not fit are trimmed equally from both sides. This is how profile pictures and thumbnails are usually made.

Exact size: show whole image with margins. The entire image is visible and the empty space is filled with a colour of your choice. Useful for product photos on a white background or for images that must not lose any detail.

None of the modes stretches or squashes your picture.

Platforms change their recommendations from time to time, so check the current guidelines of the service you are uploading to.

PNG or JPG?

JPG is the right choice for photos: files are small and the quality loss is invisible. PNG is lossless and better for screenshots, logos and images with text. If your file is still too large after resizing, use the Image compressor to reduce it further.

Frequently asked questions

What is the maximum size?

Up to 8000 pixels per side and 32 megapixels in total, which covers everything from tiny icons to large print images.

Can I make an image larger?

Yes, but enlarging cannot add detail that was not in the original, so big enlargements look soft. Reducing size always gives the best results.

Are my photos uploaded?

No. The image is drawn and resized on a canvas inside your browser and saved straight to your device.
