Resize Image questions
Short answers, then the practical details.
How do I resize an image without stretching it?
Keep the aspect-ratio checkbox enabled, then change either width or height. The other dimension updates from the source proportions, preserving the image’s shape. Disable the checkbox only when you intentionally need an exact width and height; forcing different proportions stretches the image rather than cropping it.
Can I enlarge an image and recover detail?
You can choose larger pixel dimensions, but resizing cannot recreate detail missing from the original image. Enlarged pictures may look softer or pixelated. For forms and profile photos, use the required dimensions and review the actual output rather than assuming more pixels always mean a better photograph.
What image dimensions are supported?
Use whole-number width and height values from 1 to 8192 pixels, with a combined output area of at most 16 megapixels. Source images can contain up to 40 megapixels and must fit the 50 MB per-image limit. These bounds help protect browser memory on mobile devices.
