Resize an image to specific dimensions in pixels.
Different platforms and use cases call for different image dimensions: a profile picture needs to be square, a banner needs specific width and height ratios, and an upload form might reject anything above a certain pixel size. Resizing an image changes its actual width and height, which is a different operation from compression (which reduces file size without changing dimensions).
This comes up often when preparing images for social media profiles and covers, resizing product photos to match a store's required dimensions, or shrinking an oversized photo before adding it to a document or presentation.
Upload your image, then enter the target width and height in pixels. The tool resizes the image accordingly and lets you download the result immediately. Many resizing needs also involve keeping the original aspect ratio, so adjusting one dimension automatically informs the other when proportional scaling is used.
If you change width and height independently without keeping the original ratio, the image can appear stretched or squashed. To avoid this, keep the same proportion between width and height as the original.
Enlarging an image beyond its original resolution generally reduces sharpness, since the tool has to generate new pixel data that wasn't in the source image. Resizing down to a smaller size preserves quality much better.
Resizing scales the entire image up or down while keeping all of the original content, whereas cropping removes parts of the image to change its dimensions.
Resizing to smaller dimensions usually reduces file size as a side effect, since there's less pixel data to store, even without applying separate compression.
No — the resizing happens locally in your browser and the file isn't uploaded to or kept on a server.
