Features
Professional image editing for photographers, designers and print shops: layers and masks, a full photo editor, one-click background removal and true CMYK, in a fast native Linux app.
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.
Photo Editor
Develop photos in a dedicated window with a large live preview and histogram. Set white balance, exposure, contrast, highlights, shadows, whites and blacks, then apply the result to a layer, or keep it editable as a filter on an Embedded Object.
Background Remove
Auto-Detect finds the subject in one click. Paint Keep and Remove strokes to guide it, and edge matting keeps fine hair. Send the result to a selection, a layer mask or a new layer with a mask.
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.
Color & Prepress
Edit in true CMYK and check every ink plate in the Channels panel. Add spot-color and multichannel separations, assign ICC profiles, soft-proof on screen, and watch total ink coverage so colors reproduce accurately on press.
.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
Reach for 30+ image-processing filters with real-time preview. Blur, sharpen, distort, add noise, and stylize. All filters work with selections and can be applied to individual layers for precise, non-destructive compositing.
Painting & Tablets
Paint with a graphics tablet and pressure and tilt shape every stroke, and the pen's eraser end just works. With a mouse, Fog Panther simulates pressure from how fast you draw.
File Format Support
Import files from any workflow. Fog Panther reads and writes all major image formats, including layered PSD files with layers, masks, and text preserved.

And Much More
Every tool you need, nothing you don't.
Persistent Undo History
Full undo history saved with your project. Close and reopen -- every step is still there to revisit.
Layer Groups & Organization
Group related layers into collapsible folders. Keep complex projects tidy and navigable.
Smooth Zoom & Pan
Navigate your canvas fluidly with smooth zoom, pan, and fit-to-window controls.
Crop & Transform
Crop, resize, rotate, and flip your images and individual layers with precision.
Color Picker & Fill
Pick colors from anywhere on canvas. Bucket fill with configurable threshold.
Large Image Performance
Handles massive images smoothly — even multi-gigapixel files stay responsive.
Actions & Batch Processing
Record a sequence of edits once, then replay it across a whole folder of images. Automate the repetitive work.
Command Palette
Press Ctrl+K to jump straight to any tool, filter, or command — no hunting through menus.
High Dynamic Range
Open and save 32-bit OpenEXR and Radiance HDR files, and edit in 16- and 32-bit float for the widest tonal range.
Warp Tool
Push, pull, and reshape pixels with a flexible mesh warp for precise local distortion.
Right-to-Left & Arabic Text
Full RTL and Arabic-script support with correct shaping and visual cursor navigation.
Made Specially for Linux
One platform, so every hour of development goes into making it fast and at home.
Written in C on GTK 4
Linux's own toolkit, with no web runtime and no cross-platform layer. Fog Panther follows your system theme and feels like part of your desktop.
GPU & SIMD Acceleration
Filters run on the GPU through Vulkan, the canvas is drawn with OpenGL, and blend modes use SIMD instructions. A tiled engine keeps very large documents responsive.
Packages for Your Distribution
Native .deb, .rpm and Arch packages, plus Flathub, the Snap Store and AppImage. Thumbnails and SPACE-bar previews for .fog and .psd files in GNOME Files.
