Our verdict on ImageGlass
ImageGlass is a desktop image viewer for people who need broad file-format coverage across Windows, macOS, and Linux. It opens more than 90 formats, including SVG, HEIC, WEBP, animated images, HDR formats, and camera RAW files. The feature set also covers zoom, pan, slideshows, multiple window modes, folder thumbnail previews, color management, basic HDR support, a color picker, basic editing tools, and EXIF metadata viewing through ExifGlass. ImageGlass Classic suits users who want a free, open-source viewer under GPLv3, while Pro adds licensing and support options for personal, team, and business use.
Pricing is structured around a free Classic plan and paid Pro tiers. Classic includes unlimited users, GPLv3 licensing, and all versions. Pro Individual costs $14.90 one time for one user or device, personal use, and ImageGlass 10.x updates. Pro Team costs $69 one time for up to three users or devices with Commercial Pro licensing and ImageGlass 10.x updates. Pro Business costs $9.99 per seat per month or $99 per seat per year, adding seat-based licensing, priority support, and all versions while subscribed. The published Pro notes state that direct purchases are final and non-refundable.
ImageGlass stands out for combining format breadth with desktop flexibility and a focused inspection toolkit. ExifGlass extends the metadata workflow, while plugins and external tool support can fit users who want to adapt the viewer around existing processes. It is a strong choice for photographers, developers, and general desktop users who value RAW support, metadata, and cross-platform access without an upfront cost. Users seeking advanced comparison workflows should look elsewhere for now because side-by-side A/B comparison is still in development. Likewise, those needing more than basic editing or HDR capabilities may prefer a dedicated image editor.
