Everything in one place
Pro photo editing tools, free in your browser
A complete color-editing workflow — the same tools you know from Lightroom and Capture One, running on your GPU with zero install.
Tone curve editor
A precise point curve with RGB and per-channel red, green and blue control — the tool behind every film look and faded-black style.
HSL color mixer
Shift hue, saturation and luminance across 8 color bands. Fix skin tones, deepen blue skies or mute distracting greens in seconds.
Color grading wheels
Cinematic 3-way color grading for shadows, midtones and highlights with blending and balance — teal & orange has never been easier.
Film presets & filters
Built-in film simulation, analog and cinematic looks with an Amount slider — plus import your own Lightroom .xmp presets.
Masking & local edits
Paint with a brush, drag a linear gradient or target a luminance range, then adjust only that area — dodge & burn like a pro.
Black & white
Dedicated B&W mode with an 8-channel gray mixer and one-click Auto Mix for rich, punchy monochrome conversions.
Crop & straighten
Crop with aspect-ratio presets, straighten horizons and rotate — non-destructive, re-editable any time.
True RAW editing
Decode 15+ camera RAW formats in the browser with LibRaw, starting from your camera’s real as-shot white balance in Kelvin.
Batch editing
Edit a whole shoot: filmstrip with thumbnails, Copy Settings and Paste to All to sync one look across every photo.
GPU-fast, 60 fps
Every slider renders in realtime on your GPU with WebGL2 — smooth even on 40-megapixel RAW files.
Private by design
No upload, no server, no account. Photos are processed 100% on your device — nothing to leak, nothing to delete.
True RAW, not just JPEG
Open camera RAW files online — no software needed
RAW decoding is powered by LibRaw (the engine behind professional desktop apps) compiled to WebAssembly, with your camera's as-shot white balance as the starting point.
Also decodes ORF (Olympus), PEF (Pentax), SRW (Samsung), CR2, NRW and more — plus JPEG, PNG and WebP.

How to edit a photo online
- 1
Drop your photo
Drag & drop a JPEG, PNG or RAW file — or a whole shoot at once. Nothing is uploaded.
- 2
Edit & grade
Start from a preset or work the sliders: light, color, tone curve, HSL, color grading, masking, crop.
- 3
Export
Save a full-resolution JPEG or PNG. Your original file stays untouched — editing is non-destructive.
🔒 Your photos never leave your device
Most "online editors" upload your files to a server. OpticRaw doesn't: decoding, editing and export all happen locally in your browser using WebGL2 and WebAssembly. That means client shoots, family photos and unreleased work stay private — and editing stays fast, with no upload wait.
No subscription required
A free Lightroom alternative in your browser
Same editing language — exposure and tone sliders, point curve, HSL, color grading wheels, masking, presets — without the monthly plan, the install or the account. You can even import your existing Lightroom .xmp presets and keep your looks. See the full comparison →

Frequently asked questions
Is OpticRaw really free?
Yes — 100% free. No watermark, no account, no locked "pro" features and no trial period. Open the editor and start editing immediately.
Are my photos uploaded to a server?
No. Everything runs locally in your browser using your GPU (WebGL2) and WebAssembly. Your photos never leave your device, which makes it safe for private and client work.
Which RAW formats can I edit online?
Sony ARW, Canon CR2/CR3, Nikon NEF, Adobe DNG (including iPhone ProRAW and drone DNG), Fujifilm RAF, Panasonic RW2, Olympus ORF, Pentax PEF, Samsung SRW and more — decoded by LibRaw compiled to WebAssembly.
Is this a good free Lightroom alternative?
For color editing, yes. You get the same core workflow: exposure and tone sliders, point tone curve, HSL mixer, color grading wheels, masking with local adjustments, crop and presets — including importing your own Lightroom .xmp presets.
Can I convert RAW to JPEG online?
Yes. Open your RAW file, optionally adjust it, then click Export to save a full-resolution JPEG (or PNG). It doubles as a free RAW to JPEG converter.
Can I edit many photos at once (batch editing)?
Yes. Open multiple photos into the filmstrip, edit one, then use Copy Settings → Paste to All to apply the same look to the whole shoot in one click.
Do I need to install anything or create an account?
No. It is a web app — no download, no install, no sign-up. It works in Chrome, Edge, Firefox and Safari on desktop, and you can install it as a PWA if you want an app-like experience.
Does editing change my original file?
Never. Editing is fully non-destructive: your original RAW or JPEG stays untouched and you export a separate file.
