Convert NEF to JPG on Windows: 3 Methods

Convert Nikon NEF to JPEG on Windows with Photos, Lightroom, or GetCompress for delivery sizing. Keep NEF masters; export JPG for clients and MLS.

By Petr Samokhin

Nikon NEF stays the edit master. Clients and listing sites want JPEG. Develop locally, never overwrite NEF on the card backup, and write JPEG deliverables to a separate folder. Wedding and event shoots often hold hundreds of NEF files; plan read-only ingest and a writable deliverables\jpeg\ folder before you batch.

Keep the NEF master

See RAW to JPG on Windows . Related: CR2 to JPG on Windows . Paint does not open NEF. Use Photos or a RAW editor.

Method 1: Export JPEG from Photos

Best for: Smaller sets when Photos preview loads cleanly.

  1. Open NEF in Photos when preview loads.
  2. Export JPEG at high quality to deliverables.
  3. Install a Nikon codec if Photos shows a blank preview. Use Lightroom when codec install is not an option.

Email proof2048 px
MLSOften 3000 px (check rules)
Web1920 to 2400 px

Photos defaults to sRGB JPEG, which matches most portal requirements. Compare three random exports at 100% zoom before you upload the full set.

Limitation: Importing hundreds of files from D:\Jobs\ClientA\raw\ only to export JPEG is often slower than Lightroom.

Method 2: Lightroom or Capture One

Best for: Folder-based wedding and event shoots.

  1. Import NEF with a sync preset.
  2. Export → JPEG, quality 80 to 95.
  3. Set long edge in the preset.
  4. Write output to deliverables\jpeg\.

Quality85 to 90
Long edgePortal max width

Save export presets per client so second shooters match the deliverable without asking for settings each job. Keep second-shooter NEF in a separate ingest folder until color presets match the lead shooter.

Limitation: You still need a second pass when portals reject full-res JPEG on megabyte caps.

Method 3: Size deliverables in GetCompress

Best for: Consistent width and quality across a finished JPEG folder after RAW export.

GetCompress image settings with quality, dimensions, and format options for JPEG delivery
  1. Export JPEG from Photos or Lightroom first. GetCompress is not a NEF demosaicer.
  2. Drop the JPEG deliverables folder into GetCompress .
  3. Set long edge and quality for MLS, web, or email.
  4. Export sized copies. Keep full-res JPEG masters if you may need them later.

Processing stays on your PC. Save presets per portal so the next shoot matches. For more on JPEG size after export, see how to compress images on Windows .

You can also resize with FFmpeg after export:

winget install --id Gyan.FFmpeg -e
mkdir web
Get-ChildItem deliverables\*.jpg | ForEach-Object {
 ffmpeg -i $_.FullName -vf scale=3000:-2 -q:v 3 "web\$($_.BaseName)-3000.jpg"
}

When a simpler export is enough

If Photos or Lightroom exports JPEG that the client accepts at the stated width, stop there.

GetCompress fits when every gallery needs the same long edge and quality, when second-shooter JPEG joins the same queue, or when a portal rejects the first upload and you want to tweak one preset instead of re-exporting from NEF. Keep ingest read-only. Never mix phone JPEG sidecars into NEF batch scripts.
