Optimage.app Overview

  • Updated March 8, 2026

Optimage is a macOS image optimization tool focused on delivering visually lossless compression with high compression ratios. It uses advanced perceptual metrics and improved encoders to shrink JPEG, PNG, WebP, HEIC, SVG, PDF, and even video files.

Designed for web developers, designers, and app teams, Optimage automates batch resizing, format conversion, metadata removal, and workflow integration through a clean, native interface.

Key Features

  • Visually Lossless Compression: Uses advanced perceptual metrics and improved encoders to reduce file sizes up to 90% while keeping images visually identical.
  • Intelligent Lossy & Lossless Modes: Automatically selects optimal compression settings and avoids double compression with smart quality assessment.
  • Advanced PNG Optimization: Converts 24-bit PNGs to smaller 8-bit indexed images with alpha transparency using perceptual color quantization and adaptive dithering.
  • Batch Processing Workflow: Resize, convert, rename, and export large groups of images with parallel processing on multicore systems.
  • Broad Format Support: Optimizes JPEG, PNG, APNG, GIF, SVG, WebP, HEIC, PDF, ICO, ICNS, and common video formats like MP4 and WebM.
  • High-Quality Resizing: Uses 128 bits-per-pixel linear light scaling with Lanczos resampling for professional-grade resizing.
  • Metadata & Privacy Protection: Removes Exif, XMP, IPTC, GPS, and hidden metadata while preserving useful file data when needed.
  • Color Management & sRGB Conversion: Maintains ICC profiles and converts to sRGB for consistent web and mobile display.
  • Command Line & Finder Integration: Includes CLI support and integrates with Finder and Sketch for streamlined workflows.

Pros

Competitor

Pros
ImageOptim Optimage often achieves higher visually lossless compression ratios, especially for PNG and JPEG files. It combines resizing, format conversion, and metadata cleanup in one app, while ImageOptim focuses mainly on compression. The $15 one-time price appeals to professionals who want more control and advanced perceptual metrics without relying on multiple utilities.
TinyPNG Unlike TinyPNG’s web-based workflow and API limits, Optimage runs locally, protecting sensitive images and avoiding upload size caps. There are no monthly API fees for individual users. It also supports more formats, including HEIC, SVG, PDF, and video, which TinyPNG doesn’t handle natively.
JPEGmini Optimage covers both JPEG and PNG optimization with advanced color management and batch resizing, while JPEGmini focuses mainly on JPEG files. Users get broader format support and workflow tools like renaming and folder export. The one-time purchase is often cheaper long term compared to subscription-based pro tools.
Squoosh Compared to Squoosh’s browser-based interface, Optimage offers automated batch processing and parallel optimization on multicore systems. It’s better suited for large libraries and repeated workflows. Local processing also keeps files private and removes the need for manual export steps per image.
ShortPixel Optimage works fully offline and doesn’t require WordPress plugins or API credits. Developers optimizing assets for apps or static sites benefit from its command-line tool and Finder integration. A flat $15 fee can be more predictable than usage-based pricing for high-volume projects.

Cons

Competitor

Cons
ImageOptim ImageOptim is free and open-source, which makes it more accessible for casual users. Optimage charges $15 after the daily free limit, and some users prefer a fully open-source tool. ImageOptim also has a longer presence in the macOS ecosystem, which builds stronger community trust.
TinyPNG TinyPNG offers simple web and API integrations for teams working directly in CMS platforms. Optimage lacks built-in cloud automation or direct CMS plugins, so teams managing WordPress or Shopify sites may find TinyPNG easier for continuous deployment workflows.
JPEGmini JPEGmini markets heavily to photographers and integrates tightly with Adobe tools. Optimage supports professional formats but doesn’t position itself as deeply inside Adobe ecosystems, which may matter for studios relying on Lightroom or Photoshop plug-ins.
Squoosh Squoosh runs entirely in the browser and works across platforms without installation. Optimage currently focuses on macOS, with Windows and Linux listed as coming later. Cross-platform teams may see Squoosh as more flexible for quick one-off compression tasks.
ShortPixel ShortPixel automates optimization at the server level for WordPress sites, reducing manual steps. Optimage requires local processing and file management, which adds friction for teams wanting automatic, background compression tied directly to their website infrastructure.

Verified Customer Reviews

  • macupdate.com Review: One photography site webmaster wrote that Optimage achieved better size reduction and compression than anything else tested, with output quality “virtually identical” to the original. Another user called Optimage their “absolute winner” after trying many optimizers and highlighted the mix of image quality, speed, and design. A separate comment complained that version 3.5.1 does not support M1/M2 silicon Macs and asked when that support will arrive.
