Image Colorizer
Tint any photo with an HSL color wash — hue 0–360° (default 200° blue), saturation 0–100% (default 60), brightness −40–40% (default 10) — painted in hue-blend mode over the full-resolution image. Exports JPEG at quality 0.9 as colorized_photo.jpg; nothing uploads. Photos never leave your device — processing runs locally in your browser with Canvas and WebAssembly.

Frequently Asked Questions
How accurate are the colors?
Not object-aware at all — one uniform HSL wash covers the whole photo (fill hsl(hue, saturation%, 50+brightness%) in hue-blend mode). Skies, skin, and grass all shift together; there is no AI guessing era-typical colors.
Which photos colorize best?
Grayscale or dull photos take the tint cleanly since the hue layer has no competition. Already-colorful shots get hue-shifted instead — lower saturation toward 20–30% for a subtle grade.
Can I adjust the result?
Yes — hue 0–360° (default 200° blue), saturation 0–100% (default 60), brightness −40–40% (default 10). Re-tune and press Apply Tint again; each run re-renders from the uploaded original.
Do family photos upload?
No — tinting runs locally in your browser on Canvas. Saves never touch a meter — downloads on local tools are unlimited.

Photo Retoucher
Retouch portrait photos with two paint-on brushes: Skin Smoothing (3×3 box blur inside a circular brush) and Red-Eye Remover (red-dominant pixels neutralized to grey). Brush runs 5–100px; the snapshot saves as JPEG 0.95 (retouched-<name>) when you lift the mouse — local Canvas pixel work, unlimited saves.
Unblur / Sharpen
Sharpen soft photos with a 3×3 convolution kernel (center 1+4f, arms −f, f = max(0.5, intensity)) — or add Gaussian/motion blur artistically. Intensity 1–10 (default 5); motion kernel caps at 15px with 0–360° angle; live 400px preview debounced 150ms; JPG/PNG/WebP output (quality default 0.92) — local processing, unlimited saves.
