Better JPEG Lossless Resave plug-in for Adobe Photoshop and Adobe Photoshop Elements is a software designed to avoid recompression losses when resaving edited JPEG images in Photoshop. The plug-in takes advantage of the fact that JPEG images consist of a number of small independent blocks and does not recompress unchanged blocks.
The plug-in consists of two components:
- Better JPEG Lossless Import.
- Better JPEG Lossless Export.
Each component appears in an appropriate location in the Adobe Photoshop main menu after installation of the plug-in: You will find them in the "Import" and "Export" submenus under the main menu "File" item.
Main Features:
* Opening (import) of JPEG images for lossless and nearly lossless modifications.
* Lossless rotation and/or flip of JPEG images.
* More accurate decoding of JPEG images (reconstruction), resulting in less JPEG artifacts.
* Resaving (export) of edited JPEG images without full JPEG recompression.
* Preservation of image metadata (EXIF parameters, comments etc.).
* Update of EXIF thumbnail (optional).
* Optimization of Huffman Tables.
* Original file time preservation (optional).
* Recompression statistics.
This plug-in is most helpful when only a part of a JPEG image requires editing and it is important to protect other parts of the image from degradation in quality. In other words, it can be used for image modifications such as:
* adding text, date stamps, watermarks
* removing/correcting objects such as birthmarks, red eyes, pipelines, garbage, date stamps, etc.
Each time you resave your images with the plug-in you can be sure that only the modified portions are recompressed and not a single pixel in any unmodified blocks is altered.
Another typical use of the import plug-in is reconstruction of overcompressed JPEG images by using more accurate decompression method provided by the plug-in.
