Black & White Editor - Effects

Black and white photo editor with 10 conversion algorithms, precise tone controls, color toning, and film effects — entirely offline, no account. Open any photo and instantly see all 10 conversions applied to your image side-by-side in the filter panel. Pick the one that fits your shot, then refine every parameter — no guesswork, no generic previews. Conversions: • Mono — neutral camera luminance • Noir — high-contrast Hollywood look • Tonal — graduated, softly graded tones • Luminosity — perceptual response, closest to how the eye sees • High Contrast — punchy, graphic monochrome • Red Filter — lifts skies, darkens foliage • Green Filter — smooths skin, open shadows • Blue Filter — cool, atmospheric shadows • Infrared — glowing highlights, dreamlike foliage • Channel Mixer — manual RGB weighting for total control Adjustments: • Filter Strength — blend converted and original for partial desaturation • Exposure, Brightness, Contrast, Highlights, Shadows, Gamma — full tone control chain • Channel Mixer sliders (R, G, B) when selected Color Toning: • Sepia, Selenium, Cyanotype, Coffee, Cool — add a warm or cool tint after conversion • Tone Strength slider for precise intensity Film Effects: • Film Grain — adds authentic texture • Vignette — frames the subject with a subtle darkened border • Light Rays — sunbeam effect for dramatic impact One-Tap Presets: • Classic Noir, Fine Art, Vintage Sepia, Cyanotype Print, High Key, Infrared Dream • Each preset bundles a conversion, tone settings, toning, and effects — apply in one tap, then refine Before/After Compare: • Preview (processed only) or Split view — colour original beside the monochrome result Export: • JPEG, PNG, TIFF, and HEIC output • Quality slider for JPEG and HEIC • Save As with full file-location control • Share directly from the app History: • Undo and redo for all discrete edits • Keyboard shortcuts: ⌘Z / ⌘⇧Z Who it's for: Photographers who want darkroom-grade monochrome conversion beyond what Photos offers. Designers who need precise toning (selenium, cyanotype) for archival or fine-art output. Anyone who wants to see every conversion option on their own photo before committing. Privacy: Every operation runs locally on your machine. No account, no upload, no network connection of any kind. Your photos never leave your device.
