How does Optimage achieve 'visually lossless' compression compared to other tools?
Optimage utilizes novel perceptual metrics and improved encoders to reduce image size by up to 90% while ensuring the optimized image is visually indistinguishable from the original. This is validated through third-party tests where it consistently scores 100% on visual indistinguishability, outperforming many other popular compression tools.
Can Optimage optimize images for specific platforms like social media or mobile apps while preserving quality?
Yes, Optimage is designed for this. It can optimize images for social media platforms like Twitter, Facebook, and Instagram to ensure faster uploads and preserved quality. For mobile apps, it follows Apple's HIG and Google's Android guidelines to optimize assets, including app icons and iMessage stickers, reducing app size and improving performance.
What types of metadata does Optimage remove, and what metadata does it preserve?
Optimage securely removes personal information and hidden metadata such as Exif, XMP, IPTC, GPS geotags, comments, and thumbnails to protect privacy. However, it intelligently preserves useful metadata like Android 9-patches and aPNG data, which are crucial for specific application functionalities.
Beyond standard image formats, what other file types can Optimage optimize?
In addition to common image formats, Optimage can compress PDF documents to a maximum resolution of 150dpi, which is ideal for web and email sharing. It also minimizes bloated SVG or PDF vector graphics produced by design tools like Illustrator, Photoshop, or Sketch, making them more efficient for websites and apps.
How does Optimage handle color management during the optimization process?
Optimage provides full color management with ICC profile support. It can convert images to sRGB for consistent color representation across web and mobile platforms, ensuring that optimized images maintain their intended visual appearance regardless of the display device.
