Frequently Asked Questions
Image dimensions refer to the width and height of an image in pixels (e.g., 1920 × 1080). File size refers to how much storage space the image file occupies (e.g., 2.4 MB). Two images with the same dimensions can have very different file sizes depending on format, compression, and content complexity. Resizeify lets you control both independently.
