LLCrop

Loss Less Cropping and Image Rotation: Remove unwanted parts of jpg photo without quality loss.

While there are many apps capable of cropping images (often with additional features), they generally cause quality loss because they re-encode to JPEG againwhen saving the output file.

LLCrop (the "LL" stands for lossless) cancrop JPEG images without quality loss because it crops the raw JPEG image without re-encoding the file. It also preserves embedded metadata (EXIF/IPTC and XMP).

Simply load a JPEG image from the in-app image browser, adjust the rectangular selection, rotate it if necessary and save it as a new image file.

Note: This app is focused on lossless JPEG image manipulation, so issues that propose additional features (e.g. support for other file formats, add resize-support or adding text to images) are out of scope.
