RawRoom Open the editor

Raw editor · browser-native · 100% local

A darkroom that runs in a browser tab.

Drop in a raw file, develop it, export it full size. No install, no account to start, and no copy of your picture leaving your machine.

Open a file and it is editable in about two seconds. LibRaw, compiled to WebAssembly, does the decode; the develop panel runs as GPU shaders. The only things that use the network are signing in and checking your licence. Your photographs are not among them.

A photograph developed in RawRoom: a coupe in a garage at dusk, graded through a warm film look, shown at full quality.

What leaves, and what doesn't

Your photos never leave. Here's exactly what does.

Most "cloud" editors upload your raw file, process it on a server, and send back a JPEG. RawRoom doesn't have a server in that loop. The file is decoded and developed on your own hardware, in the tab. So instead of asking you to trust a promise, here is the whole list of what crosses the network and what doesn't.

Stays on your machine

  • The raw file you opened. RawRoom reads it; it never copies it anywhere.
  • The decode and every adjustment. All of it is computed locally on your GPU.
  • The full-resolution JPEG you export. Written straight to your downloads, not fetched from us.
  • The edit itself. Close the tab and the photo is gone from RawRoom unless you saved the export yourself.

Uses the network

  • Your email, when you sign in. We send a one-time link; that is the account.
  • A licence check, so the app knows whether you own it or are on the trial.
  • A count of trial exports used. A number, not a picture.

That's the entire list. No thumbnails uploaded, no "we may use your content to improve our services," no model training on your negatives. The pictures are yours and they stay that way.

The editor

A real develop panel, not a set of filters.

Drop a file and you land in a dark, colour-neutral room with the photo at full size and the tools down the right edge. Light: exposure, contrast, highlights, shadows, whites, blacks. Colour: temperature, tint, vibrance, saturation. A tone curve. Geometry: crop to real film formats, straighten, rotate. Hold Space to see the untouched original; let go to return to your edit. When you have it, one button renders a full-resolution JPEG through the exact pipeline you were previewing, on your own GPU. What you saw is what you exported.

The RawRoom editor: a coupe photographed at dusk open in the workspace, with the Develop panel on the right showing the Develop and Film tabs, quick-develop presets, and Light, Colour, Tone curve and Geometry sections. Several readouts — exposure, contrast, shadows, vibrance — are lit amber where the image has been adjusted. The file info, compare and export controls run along the bottom.

The develop panel, up close

Everything a darkroom needs. Nothing it doesn't.

Light Exposure, contrast, highlights, shadows, whites, blacks. Six sliders that move real tonal values on a 16-bit decode, not a preview LUT.
Colour Temperature, tint, vibrance, saturation. Warm it, cool it, or leave it exactly where the camera saw it.
Tone curve A full RGB curve you shape by hand, over the frame you're working on.
Geometry Crop to 3:2, 6×6, 6×7 or XPan, straighten by degree, rotate. The formats a film shooter thinks in.
The same panel, in the app

The rail lights amber only where you've touched the image.

Film looks

Colour that came off a film stock, not a slider.

The looks are 3D LUTs built from a real colour pipeline, one per stock, grouped the way you'd think of them: colour negative, slide, cine, black and white. Dial the strength from nothing to full, compare against your straight develop, and crop to the format the stock belongs in. A starter set ships with the editor. The bigger collections come as packs when you want them.

What's next

Being built now, toward a tool you trust for output.

RawRoom develops and exports today. The panel keeps deepening in the open. As each of these ships, it joins the develop panel above rather than becoming a reason to rebuild the page.

Questions people actually ask

Straight answers.

Why run a photo editor in a browser?

Because it installs nothing and runs the same on any machine you sit down at. The raw decoder is compiled to WebAssembly and the colour work runs on your GPU through WebGL2, so a tab is genuinely fast enough for a 36-megapixel file. A desktop app is in the works for people who want one; the browser is where RawRoom lives today, and it is not a compromise version.

Is it safe? Where do my photos actually go?

Nowhere. The file is decoded and developed on your own hardware, inside the tab. No copy is uploaded, no thumbnail is sent, nothing is kept on a server. The only things that use the network are your sign-in email and a licence check. Your account travels; your pictures don't.

Why a one-time purchase instead of a subscription?

Because RawRoom doesn't cost anything to run while it sits open on your machine, so it would be strange to bill you monthly. You pay once and it's yours. If that ever has to change, existing owners keep what they bought.

Does it work in Safari or Firefox?

It runs in both, but RawRoom needs a browser feature called cross-origin isolation to thread the raw decoder, and Chrome and Edge give it the most room. Safari and Firefox work and can be slower or cap very large files. If you have the choice, use desktop Chrome. That's where it's happiest.

What happens to my photo when I close the tab?

It's gone from RawRoom. There's no catalogue quietly holding copies and no upload sitting on a server. If you want to keep an edit, export the JPEG. Saving your adjustments locally, so you can pick a file back up, is on the way, and it keeps the same rule: your settings are stored on your machine, never the image.

Do I need an account to try it?

Not to start. Open the editor, drop a file, and develop — editing and film looks need no account. You sign in when you want to export, and the trial gives you 50 exports over 30 days with no card.

Which cameras and formats does it read?

Raw from most current bodies: NEF (Nikon), RAF (Fujifilm), CR3 (Canon), ARW (Sony) and DNG. It also opens ordinary JPEG, PNG and WebP if you just want to develop those. Exports are full-resolution JPEG, with more format and resize options landing soon.
