What is Image Resizing?
Image resizing changes the pixel dimensions of an image. This is one of the most common image operations — whether you need to fit an image into a specific layout, reduce file size for faster web loading, or prepare images for social media platforms with dimension requirements. This tool resizes images entirely in your browser using the Canvas API, with no server upload needed.
