Optimage 3.5.1

Optimage 3.5.1

Optimage is an advanced image-optimization tool to minimize images in a visually lossless way for websites, apps, storage, and sharing. It uses advanced metrics to automatically adjust image quality for up to 10x smaller image files that are visually perceived as originals. Maximum compression ratio is achieved by exhaustively trying various compression parameters and image-data structures, using novel and traditional heuristics.

Simple native GUI and universal CLI clients are built to work efficiently across many different platforms on desktops and servers.

Automatic image compression

  • Intelligent lossy and lossless image compression
  • Achieve consistent good quality with custom perceptual image quality metrics and improved encoders
  • Nearly optimal image compression, the highest lossless compression density among known compressors
  • Avoid double compression with smart no-reference image quality assessment
  • Intelligently convert 24-bit PNG images to much smaller 8-bit indexed color images with full alpha transparency using perceptual color quantization and adaptive dithering
  • Greatly reduce the size of full-color images using alternative near-lossless compression
  • Full color management with ICC profile support
  • Convert to sRGB for consistent color on the web and mobile
  • Automatic chroma subsampling and grayscale conversion
  • Securely remove personal information and hidden metadata (Exif, XMP, IPTC, GPS geotags, comments, thumbnails, etc) while preserving some useful metadata (Android 9-patches, aPNG, etc)
  • Automatically and losslessly rotate photographs based on Exif Orientation tag
  • Scale a video or animation and adjust the frame rate for optimal file size

Powerful image workflow

  • Set up batch processing to streamline the optimization of large numbers of images
  • Fast and autoscalable parallel processing on modern multicore systems
  • Full control over optimization process with pausing and automatic termination
  • Resize, convert and rename images in batch mode
  • High-quality image scaling in 128 bits-per-pixel linear light using Lanczos resampling
  • Configurable file renaming and destination folder, absolute or relative
  • Export optimized files to a chosen folder preserving subfolder structure
  • Copy or move files using drag-and-drop or clipboard
  • Overwrite or move originals to Trash to restore any time
  • Preserve file timestamps to keep your library in order
  • Fully native app available for Mac, Windows (coming later) and Linux (coming later)
  • Simple command line tool to integrate into your image workflow
  • Seamless integration with Finder and Sketch
  • Quickly share optimized images using extensions in the Share menu

Support for industry standards

  • Optimize all common image formats including JPEG, PNG, APNG, GIF, SVG, WebP, HEIC and PDF
  • Optimize most common video formats including MPEG-4, H.264, WebM, Ogg and AV1
  • Minify ICO Windows icons, or favicons, and ICNS Apple icons

High-quality format conversion

  • Convert all common image formats supported by your system including HEIC, JPEG2000, TIFF and RAW
  • Convert between animation and video formats including GIF, APNG, WebP, MP4, WebM, Ogg Theora, HEVC, AV1 and ProRes
  • Convert Apple’s new high efficiency image format HEIC to optimized JPEG, PNG or WebP for sharing
  • Convert a camera raw image to JPEG or WebP image optimized for sharing
  • Convert an animated GIF to efficient MP4, WebM or AV1 video using accurate dithering removal and color depth restoration
  • Create a high-quality animated GIF from MOV, MP4, WebM, Ogg or ProRes video using improved color quantization and error diffusion dithering
  • Avoid the color shift when converting an animated GIF, APNG or WebP to MP4 video
  • Easily create responsive images and thumbnails using high-quality scaling
  • Generate high-quality previews for PDF, PSD and AI documents
