About Edit tools

Resize takes exact pixel dimensions or a percentage, with the option to keep the aspect ratio locked so nothing stretches. Crop gives you a draggable selection over the image. Rotate and flip fix orientation, including photos that arrive sideways because the camera recorded rotation in metadata rather than in the pixels. Bulk resize runs the same dimensions across a whole folder at once.

Filters and watermarks change how the image reads rather than its geometry — adjustments for tone and colour, and text stamped across the image at a size, position, and opacity you control. Every tool in this category runs in your browser, so the file is never uploaded anywhere. Resizing down always looks better than resizing up: shrinking discards information, enlarging has to invent it.
