Features
Professional-grade tools for digital artists, photographers, and designers. Built natively for Linux with GTK4 for maximum performance.
Layer-Based Editing
Work non-destructively with a full layer system. Organize your work into logical layers, apply blend modes, control opacity, and use layer masks for precise compositing.
Embedded Objects
Scale, rotate, and warp without ever touching the original pixels. Embed full-resolution originals or link external files that auto-update when changed. Place the same Embedded Object multiple times -- edit once, every instance updates.
.fog — Full Fidelity, Zero Compromise
The .fog native file format captures your entire project state
with perfect round-trip fidelity. Close your project today, open it next year --
every layer, mask, Embedded Object, blend mode, and adjustment is exactly where
you left it. No flattened layers, no lost data, no surprises.
Professional Toolset
Everything you need for serious creative work.
Non-Destructive Adjustments
Apply adjustment layers that modify appearance without altering pixel data. Stack object filters, tweak levels and curves, and fine-tune color grading -- all reversible at any time.
Selection & Retouching
Make precise selections and retouch with professional tools. Isolate subjects with geometric or freehand selections, heal blemishes, and separate skin texture from tone with frequency separation.
Text & Embedded Fonts
Add styled text to your compositions with full font support. Embed fonts directly into your project so designs look right on any machine -- no missing-font surprises when you share files.
Filters & Effects
Apply professional image processing filters with real-time preview. All filters work with selections and can be applied to individual layers for precise, non-destructive compositing.
CMYK & Color Management
Prepare print-ready artwork with full CMYK support. Assign ICC profiles, soft-proof on screen, and export with confidence that colors will reproduce accurately on press.
File Format Support
Import files from any workflow. Fog Panther reads and writes all major image formats, including Adobe Photoshop PSD files with layer preservation.
