Understanding Image Resizer
Image resizing changes pixel dimensions. It can reduce file size and prepare assets for websites, social cards, documentation, or email, but the output quality still depends on the source image and chosen dimensions.
Preserve the aspect ratio
Keeping width and height proportional prevents stretching. If the destination requires a different shape, crop intentionally instead of forcing the original image into unrelated dimensions.
Resize before publishing
Serving an image much larger than its display size wastes bandwidth. Export near the largest size the layout needs, while retaining a higher-quality source file for future edits.
Privacy and metadata
Processing occurs in the browser, but you should still review downloaded results. Resizing workflows may not preserve every color profile, animation frame, or metadata field from the original file.
