Stack multiple adjustments in one session — brightness, contrast, saturation, sharpen, blur, and color filters all in a single workspace. Each layer updates in real-time so you can see exactly how your edits combine. Perfect for quick touch-ups, social media content, and product photography. No software to install, no account to create. Your photos are processed 100% in your browser for complete privacy.
The imagemochi Photo Editor is a unified adjustment panel for brightness, contrast, saturation, warmth, sharpness, blur, and filters. All adjustments composite live on the Canvas GPU path, so you see the result the moment you move a slider — no preview lag, no waiting. This section explains what each control does mathematically, how to stack them for common looks, and why order matters.
Adds a constant value to every pixel's RGB channels. Positive values lift all tones uniformly; negative values darken uniformly. Doesn't respect tone ranges — pure whites go to pure white and stay there (clipping). Use for global exposure fixes on correctly-exposed photos.
Steepens the curve around mid-gray (128). Positive values push dark pixels darker and bright pixels brighter; negative values compress the tonal range toward gray. Also causes clipping at extremes. Use to add punch to a flat photo or soften an over-contrasty one.
Increases or decreases the distance of each pixel from its grayscale equivalent. 0% = full colour; -100% = grayscale; +50% = noticeably punchy. Does not affect luminance. Use cautiously — saturation beyond +30% on skin tones looks artificial.
Shifts colour temperature along the blue↔orange axis, simulating white-balance changes. Positive warms (tungsten feel); negative cools (daylight/shade feel). Affects skin tones strongly, skies less so. Use to correct mismatched white balance or stylize mood.
Applies an unsharp-mask convolution: the image minus a blurred copy of itself, scaled and added back. Accentuates edges without touching flat regions. Use cautiously — over-sharpening creates halos around high-contrast edges and amplifies noise in smooth areas.
Gaussian blur convolution with adjustable radius. Soft romantic look, noise reduction, or background suppression. Can be combined with masking for selective blur (blur face, blur background) in dedicated preset tools.
Three CSS-native stylization filters. Grayscale removes colour entirely (0–100% strength). Sepia adds warm brown tones for vintage feel. Invert flips every channel for negative/poster looks. Stack with any other filter to customize.
Rotates every pixel's hue around the colour wheel by a chosen angle (-180° to +180°). Different from Warmth — this shifts the whole spectrum (red becomes green at +120°), while Warmth only moves blue↔orange. Use sparingly for stylized swaps; combine with reduced saturation for moody palettes.
The Photo Editor applies adjustments in a fixed order: warmth → brightness → contrast → saturation → tint → colour effects (grayscale / sepia / invert) → blur → sharpen. This order is deliberate. Warmth is a colour-balance correction, so it comes first to establish the base colour. Brightness and contrast shape the tonal range on already-balanced colour. Saturation then adjusts colour strength relative to the final tonal range. Tint rotates the overall hue; grayscale/sepia/invert act as stylization steps. Blur integrates everything into a softened look. Sharpen comes last so it accentuates the final composed image rather than interim states.
If you apply the same numerical adjustments in a different order in another editor, you'll get a slightly different result. This is not a bug — it's the mathematics of signal processing. For consistency, imagemochi documents and commits to its order so that saved presets reproduce reliably.
This recipe is a starting point — adjust for your subject's skin tone and the original lighting. For flat studio light, bump contrast to +18. For existing warm sunset light, drop warmth to +3 or the skin will glow orange.
Your original file is never overwritten in memory. Every slider change triggers a fresh Canvas render from the source buffer — which is why the result updates instantly and why you can freely move a slider back to 0 and get pixel-identical output to the original. Only when you click Download does the final composited image get written to a Blob and handed to your browser's save dialog. If your browser crashes mid-edit, the original file on your disk is untouched.
This is mathematically called a "non-destructive" workflow and it's what professional editors (Lightroom, Capture One, DaVinci Resolve) use. Traditional "destructive" editors apply each adjustment as a bake-in step, so going back to the original means undoing each step in sequence. We chose non-destructive because it matches how people actually edit — "what if I go a little warmer" should not require rebuilding the entire adjustment stack.
All operations run in sRGB. If your input is in Adobe RGB, ProPhoto, or Display P3, the image is converted to sRGB on import (most modern cameras tag this automatically). The output will be sRGB with an embedded colour profile. For wider-gamut workflows, export first, then re-process in a colour-managed editor.
All adjustments run client-side via Canvas 2D — six filters use the browser's native CSS filter chain for instant live preview, two filters (Warmth, Sharpen) run custom pixel math on the final canvas during Apply. Nothing is uploaded. The live preview uses the uploaded image element directly with CSS filters applied, so slider motion feels instant regardless of resolution. The full-resolution composite only runs once when you click Apply.
Batch mode applies your adjustment preset to a whole folder, which is useful for photographers processing a shoot or marketers preparing a product line. The 30-day workflow history lets you name and reload saved presets across sessions. Free users get the full Photo Editor with unlimited single-file use. See pricing.
