The short answer: darktable is the best free Lightroom alternative. It is the only free tool that does both halves of the job, a catalog and a non-destructive raw editor, on Windows, Mac and Linux, and since version 5.6 it has optional AI subject masks and AI denoise as well. For a lot of photographers it is enough.
The longer answer depends on which half of Lightroom you use most. If you only need the editor, Affinity and DaVinci Resolve are now free too. If you only need the library, digiKam is better at it than darktable. Here are the real options, the catch in each free version, and what survives the move from your Lightroom catalog.
| Editor | Platforms | Catalog | The catch in the free version | Best for |
|---|---|---|---|---|
| darktable | Windows, macOS, Linux | Yes | None, but a steep learning curve | The closest full Lightroom replacement |
| RawTherapee | Windows, macOS, Linux | No | None; no library at all | Careful edits of a few files |
| digiKam | Windows, macOS, Linux | Yes | None; basic editing only | Organising a large archive |
| Affinity | Windows, macOS | No | AI features need a paid Canva plan | Raw development plus retouching |
| DaVinci Resolve | Windows, macOS, Linux | Albums | Export capped at 3840 px wide | Anyone shooting stills and video |
| Manufacturer software | Windows, macOS | No | Your own camera's files only | Matching your camera's own colour |
| Apple Photos | macOS, iOS | Yes | Basic raw tools, Apple only | Occasional raw and personal work |
Every one of these is free permanently, not free for a trial. Versions were checked against each project's own site in October 2026: darktable 5.6.1, RawTherapee 5.13, digiKam 9.1, Affinity 3.3 and DaVinci Resolve 21.
Darktable
darktable.org is free and open source: a lighttable for culling, rating and keywording, and a darkroom for non-destructive raw editing. The closest free match to Lightroom Classic in scope.
Good at: colour handling, particularly the scene-referred workflow, which produces cleaner highlight roll-off than most editors once you learn it. Version 5.6 added an optional AI object mask (click a subject, get an editable path around it) and AI raw denoise, both running locally. It reads Lightroom's sidecar files, which matters more than any feature list if you have years of work in a catalog (more on that below).
Hard about: the interface is built by developers for people who like knowing what each module does mathematically. The learning curve is real, and modules have names like filmic rgb and sigmoid rather than exposure and contrast.
Suits: a photographer who is prepared to spend a weekend learning a tool properly and never pay a subscription again.
RawTherapee
rawtherapee.com, also free and open source.
A raw processor rather than a library manager. No catalog, no keywording, just a very capable development engine.
Good at: detail extraction and demosaicing, which are excellent, and highlight recovery. Fine control over noise reduction.
Hard about: the interface presents a hundred sliders at once, and it renders more slowly than darktable.
Suits: landscape and technical work where you edit a small number of files carefully, rather than 800 frames from a wedding.
If the interface is what puts you off, ART (Another RawTherapee) is a free fork with the same engine and a much shorter list of tools, built to be quicker to learn.
digiKam, if the library is what you need
digikam.org is the opposite of RawTherapee: a serious library manager with basic editing attached. Face tagging, a map view, duplicate search and a database that copes with six-figure archives.
Pair it with RawTherapee or darktable for the actual development, and you have the two halves of Lightroom as two free programs.
Affinity and DaVinci Resolve, the free tiers worth knowing
Affinity is now free for individuals. It used to be a paid Photoshop rival and it now includes raw development, retouching, HDR and batch processing with no payment. Version 3.3, released in September 2026, rebuilt the raw engine and added raw presets that apply across a batch. You need a free Canva account to download. It has no catalog, so it replaces the editing half of Lightroom plus Photoshop, not the library.
DaVinci Resolve 21 added a Photo page for stills, with native raw support for Canon, Fujifilm, Nikon and Sony files, albums, ratings, tethering and Resolve's full colour tools, nearly all of it in the free version. The catch for stills is output: free exports stop at 3840 pixels wide, plenty for web galleries and too small for a large print. If you shoot video too, one free program for both is a strong argument.
The manufacturer's own software
Canon, Nikon, Sony, Fujifilm, and the rest all ship free raw software, and it is consistently underrated on one specific point: it applies the manufacturer's own colour science, so the raw file opens looking like the JPEG preview on the back of the camera.
Slow for volume, excellent for a handful of important frames.
Is there a free version of Lightroom?
No. There is no free version of Lightroom Classic or Lightroom for desktop. Adobe offers a time-limited trial, and after that it is a subscription: in the US, $11.99 a month for the Lightroom plan, or $19.99 a month for the Photography plan with Photoshop and 1TB of storage. The old 20GB Photography plan is closed to new subscribers.
Lightroom on mobile is free to install, but Adobe lists raw editing, masking, the healing brush, batch editing and sync as premium features. It is a usable free phone editor, not a free Lightroom workflow. Google's Snapseed does selective adjustments and opens raw files on a phone with no subscription.
If you want to pay once rather than subscribe
Many people searching for a Lightroom alternative object to renting, not to paying. Three serious editors still sell a licence you keep:
- DxO PhotoLab 9: around $240, with paid upgrades when a new major version ships. Strong on lens corrections and denoise.
- ON1 Photo RAW 2026: around $100, and frequently discounted. Includes a catalog, so it replaces both halves.
- Capture One Pro: a perpetual licence is still sold, but it gets bug fixes only. New features after you buy go to subscribers.
Licensing terms in this corner of the market change often, so check the current price on the vendor's own page before you commit.
For a working photographer that is often a better trade than a free editor: ON1 costs about five months of the Lightroom plan, and you skip the weekend of relearning darktable asks for.
What survives the move from your Lightroom catalog?
More than most switching guides say, if you prepare before you cancel.
Lightroom Classic keeps your work in its catalog, which no free editor can read. It can also write that work into XMP sidecar files next to each raw file, and darktable reads those on import. According to darktable's manual, that brings across:
- Metadata: keywords (including hierarchical ones), colour labels, star ratings and GPS locations.
- Some edits: crop and rotation, exposure and black level, vignette, clarity, tone curve, HSL, split toning, grain and spot removal.
The edits are a starting point, not a match, because the engines differ. Masks, profiles, presets and anything AI-driven do not come across.
To make the sidecars exist:
- In Lightroom Classic, open Catalog Settings, Metadata tab, and tick "Automatically write changes into XMP".
- In the Library, select all photos and choose Metadata, Save Metadata to Files (Ctrl+S or Cmd+S). This covers everything edited before step 1.
- Check a folder: each raw file should now have a
.xmpfile beside it. DNG, JPEG and TIFF files carry the data inside the file instead.
Three things live only in the catalog and are lost: collections, virtual copies and pick or reject flags. Turn picks into a star rating or a colour label before you write the sidecars, and they come with you.
Export full-resolution JPEGs of anything you might need to deliver again, and keep the folder structure as it is: the catalog is the fragile part and the folders are not, which is the whole argument for organising them properly in the first place.
What you give up by leaving Lightroom
Presets and the ecosystem. Your existing presets do not transfer. If your signature look is built on Lightroom presets, you are rebuilding it from scratch, and that is a real cost measured in days rather than hours.
Mobile and cloud sync. Editing on a phone with your desktop presets, and having a catalog that syncs, is useful for delivering sneak peeks the evening of a shoot. No free option matches it.
Publish services. A gallery link through a Lightroom publish service goes too. Delivery becomes export to a folder, then upload, which is how most photographers deliver anyway.
AI denoise and masking used to be on this list. Darktable 5.6 closed much of the gap, but the tools are new and want a decent GPU. If you shoot dark receptions at high ISO, test them on your own files before you cancel.
Who should actually switch
Switch if you are starting out and the subscription is a real cost, if you edit modest volumes carefully, or if you object to renting software and will spend the learning time.
Do not switch if you shoot high volume professionally and your workflow is already fast. The time spent rebuilding presets and relearning masks is worth more than the fee.
What Lightroom still sells is speed and the ecosystem, not image quality. If thousands of files pass through your hands a month, the time cost of the software is the thing to optimise, not the licence fee.
If you are leaving, write the XMP sidecars before you cancel, while every part of Lightroom still works. The editor is also only one line on a bill that usually has three or four; the gallery platform cost calculator prices the delivery line, commission included, with no account needed.
