What's new

157 presets in seven collections: Adjust 4 Preset List, Classic, Vibrant, HDR, Film, Toned and Stylized. Every preset shows a live thumbnail rendered on your own photo.

New effects

• Black & white with a channel mixer, sepia/selenium toning and split toning
• Creative effects: pencil and colour sketch, glow, posterize, solarize, invert
• Per-channel R/G/B curves (cross process, Lomo, colour negative looks)

Redesigned editor

• Light and dark themes that follow your system, with selectable accent colours
• Single, Split and Side by Side comparison; hold Space to see the original
• Effect stacking: Apply a look, layer another on top, Undo Layer to step back
• My Collection: save your own presets (Ctrl+S), import, export and favourite them
• True 100% zoom with full-resolution detail; the image stays fitted as you resize
• Paste images or copied files with Ctrl+V

Quality and fixes

• The preview now matches the exported image exactly
• 16-bit PNG/TIFF and transparency are kept on export; photo rotation (EXIF) is respected
• Fixed colour blotches in grey areas (e.g. skies) when boosting saturation
• Each slider drag is one undo step; editing never freezes the window
• Faster processing: blur cost no longer grows with the effect radius
