Resizing keeps the original image format. Server-side validation checks the real decoded format and applies image and output safety limits.
Resize by pixels or percentage
Set an exact width and height, keep the original aspect ratio, or scale the whole image by a percentage. Enlargement is disabled by default on the general tool so a small source is not accidentally stretched.
Format stays the same
JPG stays JPG, PNG stays PNG and WebP stays WebP. Camera orientation is normalized before resizing so portrait photos use the dimensions you see instead of unrotated EXIF dimensions.
Common exact-size presets
If a form or workflow already specifies a canvas size, open a prepared page with those dimensions filled in. Exact square dimensions can distort a non-square source, so decide whether exact size or preserved proportions matter more.
