DEPLOYED

A professional-grade photo editor that runs entirely in the browser. No upload. No account. No tracking. Every pixel stays on your machine.

Built on vanilla JS with a Canvas-2D render pipeline backed by SharedArrayBuffer workers. The color science is real — ACES scene-linear workflow, LUT precision transforms, HDR exposure fusion. Not a filter app. An editing tool.

What it does

COLOR SCIENCE

  • ACES pipeline — scene-linear Academy Color Encoding System. Same color model used in film post.
  • LUT import — .cube files, 1D and 3D, applied at full precision. Bring your own looks.
  • Rec.709 / Rec.2020 / Log C transforms — industry-standard gamut and gamma conversions.
  • Temperature + Tint — white balance in kelvin, not sliders-to-nowhere.

TONE CONTROLS

  • Brightness, Contrast, Clarity, Highlights, Shadows, Whites, Blacks
  • Saturation, Vibrance — perceptual, not naïve multiplication
  • Dehaze — cuts atmospheric haze via local contrast recovery
  • Vignette — clean edge darkening, no edge blowout

DETAIL + FX

  • Sharpen + Blur — local detail enhancement and controlled softening
  • Grain — film-grain synthesis, not noise
  • Vignette — exposure-correct falloff

HDR FUSION

Load multiple exposures. Merge into a single HDR image. Tone-map for output. Works offline, in the browser, without server round-trips.

CURVES

Master RGB curve editor. Per-channel precision. Luminance masking built in. This is the edit layer that matters.

PRESETS

  • Original, Rec.709, Rec.2020, Log C, Linear, Cinematic, B&W, Vintage
  • Save your own looks — stored locally, no sync required

SNAPSHOTS + BATCH

Compare versions with Snapshots. Apply a full adjustment stack to a folder of images with Batch mode. No queue, no cloud — local pipeline.

Architecture

Built to be fast and private. The render pipeline runs in a Web Worker via SharedArrayBuffer — the main thread never blocks during processing.

  • Vanilla JS — no framework. Direct DOM, direct Canvas API.
  • SAB render pipeline — SharedArrayBuffer passes pixel data to workers without copying. Fast.
  • Web Workers — all heavy computation off the main thread. UI stays responsive.
  • Canvas 2D — hardware-accelerated 2D compositing.
  • VitePWA + Workbox — offline-first. Install it once, use it without a connection.
  • Cloudflare Pages — deployed with full security headers: CSP, COOP, COEP, CORP, HSTS, Permissions-Policy.

COOP + COEP are required for SharedArrayBuffer in modern browsers. The editor enforces them. That’s also why it can’t be embedded in an iframe — frame-ancestors: none is intentional.

Privacy model

No image data leaves the browser. Ever.

  • No upload endpoint
  • No analytics
  • No cookies
  • No account, no login, no email
  • No subscription
  • No tracking pixels
  • Free. No catch.

The only network request is loading the app itself. After that, fully offline.
