Every image retains its original proportions, and your files are processed entirely on your device.

Fit (the default) shrinks each photo so its long edge is at most the size you choose, 2048 px unless you change it, and never enlarges a smaller photo. For an exact width and height, choose Exact: Pad adds padding (black, white, or transparent), or Crop performs a centered crop to fill the target dimensions.

Adjust exposure, highlights, shadows, contrast, saturation, hue, and blur instantly. Make saturation 0% for a grayscale image, or rotate photos right from the preview.

Settings apply consistently across your entire batch of images. In Scale mode, each photo is scaled relative to its own size. With several photos, Download all saves them as one ZIP file.

Max file size keeps each saved file at or under the size you set, for upload forms with a limit (1 KB = 1,000 bytes). It picks the highest JPG quality that fits and keeps your pixel size, and makes the photo smaller only when quality alone can't get there.
