Saving images for web/email/other media with the best compression ratio and quality is a difficult task if you don't have the right tools. Choosing the right format then choosing the right parameters are the key factors of smaller files. Previewing the resulting image and the projected filesize will help the user choose the best settings. This kind of image optimization software is often called 'Save for web'.
Features:
- open multiple graphic file formats by looking first at the magic number (it does not need file extension to recognize format)including support for uncommon images types (up to 128 BPP, integer and floating point. EX: hdr images, 16 bit grayscale, etc). Adaptive logarithmic tone mapping algorithm (Drago) used for HDR images.
- save and optimize JPEG, GIF and PNG with a simple, clean user interface.
- works in dual view: (original - optimized image) or single view (optimized image). Automatic preview of resulting image.
- compress files to desired filesize threshold.
- fast processing (all is done in memory); see instant results including resulting filesize.
- decide if you want to keep metadata (comments, IPTC, Adobe XMP, EXIF profiles, ICC profiles).
- common tools: pan and zoom, rotate, flip.
- resize image by using well known resample filters (ex: Lanczos3, Catmull Rom, Bicubic, and others).
- in-place compare function (alternativelly display the original image over the optimized image to notice small pixel changes).
- the compression and the results are comparable to those of commercial products.
