Powerful Features

Import from Photos, Files, or Camera

Import images from your Photos Library, any files, or take a photo directly with the camera.

Advanced Resizing Modes

Flexible resizing for every need:

Define the image width, height, or both.
Define the resolution in megapixels. E.g. make a 5-megapixel image.
Limit the file size. E.g. make an image file at most 1 MB.

Choose what happens when the aspect ratio changes: crop, deform, or add borders of any color. And if the image is too small: enlarge it or add borders.

Size Presets, Synced via iCloud

Save your size configurations as presets and reuse them anytime. Automatically synchronized across all your devices.

Image Formats

Save images in your preferred format:

JPEG, HEIC (iPhone 7+), TIFF, PNG, GIF, BMP

Control format-specific settings: compression quality for JPEG and HEIC, lossless compression for TIFF.

Flexible Size Units

Define dimensions in pixels, percent, inches, centimeters, or millimeters. Set print resolution in pixels per inch or per cm. Define file size in MB, MiB, KB, KiB, or bytes.
