Free Lightroom Alternatives Compared Honestly

Short answer: if you want to apply Lightroom .xmp presets or .cube LUTs without installing anything, and keep RAW files on your device, use Lightframes in a desktop browser — or read the dedicated guide on using XMP presets without Lightroom. For a full desktop RAW catalogue and module-based local edits, darktable or RawTherapee (both free, GPLv3) are stronger, but they do not read Lightroom develop presets. Photopea is a capable browser editor for layers and JPEG workflows; it opens many RAWs with basic develop sliders, but it is not a Lightroom preset replacement. Adobe’s free Lightroom mobile app covers capture and basic edits on a phone; RAW develop, selective adjustments, batch editing and synced presets sit behind paid plans, per Adobe’s Lightroom mobile FAQ.

Lightframes is a free, open-source (MIT) photo editor that runs entirely in the browser. Photos are processed on your device and are never uploaded.

Lightframes — browser RAW editor with your Lightroom presets

Best for: photographers who already own Lightroom .xmp presets or .cube LUTs, want a free Lightroom alternative online, and need RAW + batch without creating an account or uploading files.

Lightframes is an open-source photo editor that runs entirely in the browser tab. RAW files are decoded with LibRaw compiled to WebAssembly; edits, presets and exports run on your device in Web Workers. Photos are not uploaded — they are processed in your browser. Your open files and custom presets live in IndexedDB on that device.

What matches a Lightroom-style workflow in this repo:

RAW and JPEG/PNG editing, export to JPEG, PNG or WebP developed from the full-resolution RAW (RAW editor, RAW to JPG).
Import Lightroom / Camera Raw .xmp presets, plus JSON and .cube LUTs, with an intensity slider (photo presets, XMP without Lightroom).
Copy/paste edits across a filmstrip selection and batch export as a ZIP (batch photo editor).
Local adjustments with radial, linear, brush and AI subject masks (on-device).
Collage and Instagram carousel export from the same session (collage maker, carousel maker).
Retouch: heal, clone and AI object removal — the removal model is downloaded from Hugging Face the first time you use it, then runs locally (remove objects).
AI upscale on export (Real-ESRGAN via ONNX Runtime Web, model downloaded once).

Honest limits: imported XMP files map develop sliders, curves, HSL, colour grading, grain and similar settings; camera profiles, lens corrections and Lightroom-style masks are not imported, so a preset may look close but not identical (presets FAQ). LibRaw support depends on the bundled version — very new cameras can lag (RAW in the browser). The editor UI is English-only. Heavy RAW batches are more comfortable on a desktop browser than on a phone.

darktable — desktop RAW darkroom and library

Best for: a free, local RAW workflow with a real catalogue, tethering and deep modular editing — when you do not need to load Lightroom develop presets as-is.

darktable is a photography workflow application: lighttable, non-destructive RAW development and export. It is GPL-3.0 and runs on Linux, macOS, Windows and BSD (features). It reads a wide range of RAW formats via RawSpeed (supported formats), keeps edits in its database and XMP sidecars, and offers GPU acceleration (OpenCL), tethering on supported cameras and Lua scripting.

Where it is stronger than a browser editor: persistent library and filtering, many local adjustment modules, colour-managed pipeline at 32-bit float, and a mature export system including web galleries.

Trade-offs: darktable’s FAQ states that presets (styles) from other programs, including Lightroom, are not compatible; LUTs in several formats can bridge some looks (FAQ). There is no “open in browser without install” path, and no built-in Instagram carousel or collage tools like Lightframes. Photos stay on your machine because it is a desktop app — not because of a browser sandbox.

RawTherapee — precise desktop RAW processing

Best for: enthusiasts who want a deep RAW tuning tool on desktop, batch output through a queue, and are happy working in .pp3 processing profiles instead of Lightroom presets.

RawTherapee is free software (GPLv3) for cross-platform RAW development (rawtherapee.com). It offers a file browser, a detailed editor (exposure, detail, colour, transform, RAW tab) and a batch queue so you can stack exports while you keep editing (RawPedia Queue). Profiles are saved as .pp3 sidecars, with optional XMP sidecar sync for metadata (ratings, labels), not for serialising the full develop recipe into Lightroom-compatible XMP (GitHub issue #7315).

Where it is stronger: fine-grained RAW controls, partial paste of processing profiles, and a dedicated queue for overnight exports.

Trade-offs: No import of Lightroom .xmp develop presets. Film Simulation traditionally uses Hald CLUT images; community workflows often convert .cube LUTs to Hald CLUT rather than treating them like Lightroom presets. No cloud library, no browser access, no collage/carousel export.

Photopea — browser Photoshop-style editing

Best for: layers, selections, text and PSD work in the browser when the source is often already developed, or when you only need basic RAW adjustments before compositing.

Photopea runs fully locally in the browser — files are not uploaded to a server (Photopea). It opens many formats, including DNG, CR2, CR3, NEF, ARW and others listed in its GitHub readme, with a RAW import dialog (exposure, white balance, contrast, highlights, shadows, etc.) before the image becomes a normal layer stack (tutorial).

Where it shines: Layer-based editing familiar from Photoshop, without installing desktop software.

Trade-offs: It is not a catalogue RAW manager. The developer has noted that Photopea’s RAW panel does not support all Adobe Camera Raw options and that Lightroom .xmp presets are not a supported workflow (issue #5658). For preset-driven JPEG/RAW batches with XMP you already own, Lightframes is a closer fit.

GIMP (+ a RAW developer) — free editing, separate RAW step

Best for: users who already live in GIMP for retouching and compositing and are willing to develop RAWs elsewhere first.

GIMP is free software for image retouching and composition under the GNU GPL. GIMP itself does not replace Lightroom’s RAW+catalogue stack: you typically develop RAW files in darktable, RawTherapee or another RAW processor, then open the exported TIFF or JPEG in GIMP. That two-app path is flexible and free, but slower than an integrated preset batch workflow in Lightframes or a single desktop catalogue in darktable.

Adobe Lightroom free mobile tier (context only)

Adobe’s Lightroom for mobile is free for capture, organisation, sharing and most basic edits, with more than 30 built-in presets (mobile FAQ). Premium features — including RAW editing on mobile, selective adjustments, batch editing, synced presets and profiles, and cloud storage — require a Creative Cloud Photography plan or in-app Premium subscription (same FAQ). Lightroom on the web is tied to paid Creative Cloud access, not the free mobile tier (Adobe plan comparison).

If your goal is specifically “use the .xmp presets I bought without paying for Lightroom” on a laptop browser, that use case is outside Adobe’s free mobile offering.

How to switch: use your Lightroom presets (`.xmp`) without Lightroom

Pick a host that imports develop presets. In Lightframes, open the editor, go to Presets → Import, and choose your .xmp file (or a .cube LUT). See photo presets for what is mapped.
Start from a representative photo. Apply the preset, set Intensity, then fix exposure and white balance per image — presets assume a neutral starting point.
Spread the look across a shoot. Ctrl/Cmd+C to copy edits, select the rest of the filmstrip, Ctrl/Cmd+V, and tick only the groups you want (for example Tone curve and HSL, not Crop). Export everything as a ZIP from the batch editor.
Keep a backup. Download your custom presets as JSON from the Presets tab so you can restore them after clearing browser data.
Expect small differences. Without Lightroom camera profiles, lens corrections or masks, some purchased presets will need a manual tweak — the same limitation is documented in make photos look like film for film-style looks.

Common questions

What is the best free Lightroom alternative online? For RAW files, .xmp presets and batch export in the browser without uploading photos, Lightframes is the closest match in this list. For layer compositing, try Photopea. For library management and deep local RAW modules, install darktable or RawTherapee.

Can darktable or RawTherapee open my Lightroom presets? Not as Lightroom develop presets. darktable’s documentation says styles from other programs are not compatible (FAQ). RawTherapee saves edits in .pp3 files; putting PP3 data into XMP for other apps is a requested feature, not the default workflow (issue #7315). You can still reuse .cube LUTs with conversion or import paths described above.

Does Photopea upload my RAW files? Photopea states that processing runs on your device and files do not leave it (Photopea). That is separate from whether it applies your Lightroom preset pack — which it does not, in the sense Lightroom users expect.

Is Lightframes private? Photos are not uploaded; processing happens in your browser. AI tools download their models once (object removal from Hugging Face; other models from the Lightframes site). That is on-device processing, not a claim of absolute privacy against browser extensions or local malware — it means there is no Lightframes server receiving your images.

Can I edit RAW for free on my phone without a subscription? Lightframes works on mobile browsers, but large RAWs are smoother on desktop. Adobe lists RAW editing on phone/tablet under premium Lightroom mobile features (Adobe help).

Which tool should I choose if I only shoot JPEGs with purchased presets? Lightframes: import .xmp, adjust intensity, paste across a folder, export. Photopea if you also need layers and PSD. darktable/RawTherapee if you are building a desktop archive and will recreate looks with native styles or LUTs.

Ready to try your presets? Open Lightframes, import an .xmp under Presets, and read the photo presets guide for the full import list.
