DxO PureRAW Review

What DxO says it does

DxO's product page names DxO PureRAW 6 and describes DeepPRIME denoise and demosaicing, optical corrections (distortion, chromatic aberration, vignetting), sharpness modules, batch processing and drag-and-drop (DxO PureRAW). It says processed photos return to Lightroom automatically with edits, metadata and Collections intact, and mentions a Photoshop Smart Filter integration. These are vendor statements.

Vendor claims

The page lists no culling, retouching or upscaling features, so it covers one step of the workflow, after culling and before editing. Compare options in best AI denoise software.

DeepPRIME versions and what independent write-ups report

DxO's product page names "DeepPRIME technology" without listing versions. Two independent write-ups fill in the version detail. Fstoppers reports that DeepPRIME XD3, previously limited to Fujifilm X-Trans sensors, now also covers Bayer sensors from Sony, Nikon and Canon in PureRAW 6, and that PureRAW draws on a database of camera and lens combinations for its corrections. PhotoWorkout reports the same sensor extension, that standard DeepPRIME 3 remains as a faster option, and passes on a DxO claim of "3 stops of equivalent quality improvement", which that article does not verify. PhotoWorkout says its sample images came from DxO, that it partnered with DxO on a discount code, and that it carries affiliate links. Treat the stops claim as vendor-reported with no published method, and check your own body against DxO's supported cameras and lenses page, which this page could not read from the product page.

Where your files go

DxO's page does not say whether processing is local or cloud (not found in sources reviewed), and DxO's privacy and data documentation was not read: not found in sources reviewed. No conclusion about client confidentiality can be drawn; check DxO's current documentation before using it on sensitive files.

System requirements, per DxO's shop page

The stated floor matters if you cull and edit on a laptop.

An older Mac running macOS 14 or earlier falls below the stated macOS minimum, and a Windows laptop without a discrete GPU or NPU may not qualify. Check this table against every machine you would use before starting the trial.

Example (arithmetic from cited prices, not a measurement): a new PureRAW licence at US$139.99 against Topaz Photo Personal at US$199 per year (Topaz pricing; only part of that page was read) is US$59.01 lower in year one. If you then paid the US$89.99 upgrade price every year (a hypothetical; DxO does not commit to this), two years of PureRAW is US$229.98 against US$398 for Topaz Photo. At 25 weddings a year, US$139.99 spread over one year is about US$5.60 per wedding. The licence difference is documented; which gives a cleaner file is not. The Topaz and DxO products also do different jobs, so the sum compares costs, not substitutes. See Topaz vs Lightroom Denoise and the Topaz Photo review.

Where PureRAW sits in a wedding workflow

PureRAW is a pre-processing step, so it belongs after culling and before editing, and it only needs to touch the frames you will deliver. Example (hypothetical): a 3,000-frame wedding culled to 600 means PureRAW works on 20% of the gallery, and if only the reception is high-ISO, fewer. Running it before culling would process rejects. This ordering is reasoning, not a DxO recommendation; DxO's page says photos return to Lightroom automatically.

Scenarios

A dark reception set at high ISO. DeepPRIME is described as denoise and demosaicing; DxO's page does not name receptions. The decision is licence and time per frame: perpetual with trial, against a subscription elsewhere. Time per frame and output size: not found in sources reviewed.

Ceremony frames shot with a long lens at a wide aperture. DxO lists optical corrections (distortion, chromatic aberration, vignetting). Whether those apply to your lens and body depends on supported modules; the supported camera and lens list: not found in sources reviewed. Check before the trial ends.

A photographer who delivers JPEGs straight from camera. PureRAW is described as a RAW pre-processing step, so it does not fit a JPEG-only workflow.

What the returned file does to your catalogue

DxO says edits, metadata and Collections stay intact when photos return to Lightroom. DxO's own pages read today do not name the output format. PhotoWorkout reports that PureRAW outputs a Linear DNG, with a Hi-Fi compression option that cuts size by up to four times against uncompressed DNG; it quotes one early figure of 64.5 MB uncompressed against 14.4 MB compressed from a 24.9 MB RAW, sourced to another site, and says an existing DNG cannot be compressed afterwards, so processing has to start from the original RAW. It also says HEIF and smartphone RAW files are not supported. Fstoppers describes a Lightroom Classic plug-in workflow with three launch options, a Smart Object export to Photoshop that lets you reopen the PureRAW filter later, and a warning that in standalone mode, file operations outside Lightroom do not update the catalogue, so files can go missing until you resync.

Storage arithmetic follows from the reported sizes. Example (hypothetical, using the single reported 24.9 MB RAW to 14.4 MB compressed pair): 600 delivered frames per wedding are about 14.9 GB as RAW (600 x 24.9 MB), about 8.6 GB as compressed DNG (600 x 14.4 MB) and about 38.7 GB uncompressed (600 x 64.5 MB). Keeping both the RAWs and compressed DNGs adds about 8.6 GB per wedding, or about 216 GB over 25 weddings; the uncompressed route would add about 968 GB over the same 25. The two sources use different files and do not agree: Fstoppers reports DNG outputs of roughly 120 to 150 MB shrinking to 17 to 20 MB with compression, which at 600 frames would be about 72 to 90 GB uncompressed and 10 to 12 GB compressed per wedding. Treat both sets as hypothetical inputs and measure your own ratio, because it depends on sensor size and compression setting. Also check whether you can still adjust white balance and recover highlights on the returned file.

When the licence stops

DxO lists a perpetual licence, activation on up to two computers, and an upgrade price for owners of versions 4 and 5, so past major versions were paid upgrades rather than free ones. The shop page also says an internet connection is required to use the software and specifically for activation, and that after online activation it can be used offline for 37 days before a connection to DxO's servers is required, so a perpetual licence still depends on periodic contact with DxO; plan for that if you travel or work on an air-gapped machine. Whether future major versions are paid and whether new cameras need an upgrade: not found in sources reviewed. Before buying, ask DxO in writing about upgrade pricing and activation, and keep your original RAWs and delivered files either way.

Choosing between a perpetual licence and a subscription

A perpetual licence moves the cost to the front and removes the monthly bill, but it does not tell you what future versions cost. Example (arithmetic from a cited price): Topaz Photo Personal at US$199 per year is US$398 over two years; the comparison says nothing about quality.

Honest downsides

• Future upgrade policy and refund terms: not found in sources reviewed; the shop page's pricing layout is ambiguous.
• A stated hardware floor (16 GB RAM on Windows, macOS 15.7 on Mac) and GPU or NPU requirements.
• HEIF and smartphone RAW are reported unsupported, and an existing DNG cannot be compressed afterwards (PhotoWorkout).
• Standalone use outside Lightroom can leave the catalogue out of step until you resync (Fstoppers).
• Data handling: not found in sources reviewed.
• Covers one step only; no culling, retouching or upscaling listed.
• Any pre-processing step adds a round trip, so check batch time and disk use on a large gallery.
• Supported cameras, including recent bodies: not found in sources reviewed.

Decision aid

Want a perpetual licence, shoot RAW, want lens-aware correction with denoise

use the trial.

Prefer to stay inside Lightroom or want face recovery and upscaling

see Lightroom Denoise or Topaz instead.

Unsure

run the 14-day trial on the same high-ISO file you would send to a rival.

DxO has no affiliate link here; visit DxO's PureRAW page to start a trial.

Check this in your trial

1. Process the same ISO 6400 to 25600 RAWs in PureRAW and your current tool; compare 100% crops of skin and dark fabric.
2. Confirm your camera body and lens are supported before the trial ends, and compare standard DeepPRIME 3 with XD3 on a Bayer-sensor file if your body qualifies.
3. Check how the returned file arrives in Lightroom: format (DNG), size with and without Hi-Fi compression, metadata, Collections.
4. Time 100 frames, and note what happens to the catalogue if you also process through the standalone window.
5. Ask DxO what a future major version costs, and whether any processing leaves your computer.
6. Record disk use and returned file type for that 100-frame batch.
7. Check that the camera body and lens you shot the last three weddings with appear in the supported list.

Original test pending: we would run a DxO trial on a high-ISO RAW ladder with timing and a catalogue round-trip check, because the licence advantage is documented while the quality question is open.
