Key features of uCrop that cover most common image cropping processes

uCrop’s customizability allows developers to have control over the following steps during library integration:

  • choosing the image compression format (JPG, PNG)
  • adjusting the JPG image compression quality on a scale from 0 to 100 (since PNG is a lossless format, compression quality doesn’t apply to it)
  • selecting whether all supported gestures are enabled simultaneously
  • setting the maximum size of the bitmap matrix decoded from the source URI and used in the crop view (if necessary)
  • enabling or disabling the appearance of the crop frame and guidelines
  • setting the color of the crop frame, the width of rows, and the number of columns
  • selecting either a rectangle or oval crop area
  • changing the UI colors (toolbar, status bar, active widget selection)

Use cases that highlight uCrop’s functional benefits

  • Photo editing: Applications that involve photo editing, such as adding filters or stickers, can use uCrop to let users crop images as part of the editing process.

  • Refining the quality of scanned images: Apps that involve scanning and saving documents or receipts can use uCrop to let users crop and refine

  • Preparing digital artwork and designs for publication: Drawing, painting, or design applications can use uCrop to enable users to crop and refine their artwork or designs before finalizing or sharing them.

  • Progress tracking in fitness apps: Apps involving tracking progress through images, such as before-and-after fitness transformations, can use uCrop to enable users to consistently crop and compare images.

  • Standardizing marketing and e-commerce assets: Product images in e-commerce applications often need standardized sizes and aspect ratios for thumbnails or display images. uCrop enables users or sellers to crop product images to fit these requirements before uploading.

  • Adjusting pictures for social media: In social media apps, user profiles often require cropped images of specific dimensions. uCrop’s dynamic aspect ratio controls allow users to precisely crop and adjust their profile pictures before uploading.
