NEF (Nikon Electronic Format) is Nikon's proprietary RAW image format used by all Nikon DSLRs and mirrorless cameras since 1999. Built on TIFF structure, NEF stores unprocessed 12-bit or 14-bit sensor data, preserving maximum dynamic range and color information for post-production flexibility. Files include embedded JPEG previews and comprehensive EXIF metadata including lens data, focus point, and metering information.

NEF is essential for photographers using Nikon cameras who need maximum editing flexibility. For sharing or web publishing, conversion to JPEG is necessary since RAW formats require specialized software like Adobe Lightroom, Capture One, or Nikon's own ViewNX-i and NX Studio applications.

PNG (Portable Network Graphics) provides lossless compression with full alpha channel transparency, making it the go-to format for graphics, screenshots, and images requiring pixel-perfect fidelity. Created in 1996 as a patent-free GIF alternative, PNG uses DEFLATE compression and supports both indexed color (PNG-8) and truecolor with alpha (PNG-24/32). Files are 3-10× larger than equivalent JPEGs but preserve every pixel exactly.

PNG is universally supported and ideal for logos, UI elements, diagrams, and any content where transparency or lossless editing matters. For photographic content without transparency needs, JPEG typically offers better compression efficiency.

Frequently Asked Questions

What is an NEF file?

NEF (Nikon Electronic Format) is Nikon's proprietary RAW image format used across all Nikon DSLRs and mirrorless cameras since 1999.

NEF files contain unprocessed 12-14 bit sensor data, preserving maximum dynamic range for exposure correction, white balance adjustment, and color grading.

Converting to PNG preserves this quality in a universally-compatible lossless format.

What Nikon cameras shoot NEF?

All Nikon DSLRs and mirrorless cameras: Z8, Z9, Z6 III, Z7 II, Zf, D850, D780, D500, D7500, and every other Nikon camera since 1999. NEF is Nikon's universal RAW format across their entire lineup.

Why choose PNG over JPG for NEF conversion?

PNG is lossless—no compression artifacts. Every pixel from your RAW file is preserved exactly. Choose PNG when you need to edit further in Photoshop/GIMP, print high-quality photos, or archive masters. For quick sharing or web use, our NEF to JPG converter gives smaller files with excellent visual quality.

How big are the PNG output files?

Expect 70-100 MB per image from a 45 MP Z8/Z9. PNG files are 5-10x larger than equivalent JPGs because they're lossless. A 30 MB NEF from a Z6 becomes ~50 MB PNG.

What settings are used for the conversion?

Conversion settings:

  • White balance: Preserved from your camera's as-shot settings
  • Exposure: Auto-brightness applied (matches Windows 11 Photos app)
  • Color space: sRGB with standard gamma curve
  • PNG compression: Level 6 (balanced speed/size)
  • Color depth: 8-bit per channel (24-bit RGB). Note: Nikon RAW files store 12-14 bit sensor data; outputting to 8-bit is standard for PNG/JPG—it doesn't affect visible quality for typical use.
  • Metadata: Stripped for privacy

Output matches Windows 11 Photos app. We use the same auto-brightness and color processing that Windows applies when you open a NEF file.

What happens to EXIF data (camera settings, GPS)?

Stripped by default for privacy. Camera model, lens info, GPS coordinates, and shooting settings are removed during conversion. This protects your privacy when sharing online.

How are credits calculated for this conversion?

Cost: 1 credit per 50 MB

How it works:

  • Files up to 50 MB: 1 credit (minimum)
  • 51-100 MB: 2 credits
  • 101-150 MB: 3 credits
  • 151-200 MB: 4 credits
  • Over 1000 MB: 20 credits (maximum cap)

Example: A 5 MB photo = 1 credit. A 95 MB photo = 2 credits.

Why per-megabyte? Larger files require more resources (processing, bandwidth, storage).

What are my daily and monthly credit limits?

Credit allocations vary by account tier:

TierDaily LimitMonthly Limit
Free50 credits/day
Pro10,000 credits/month
Business30,000 credits/month

Daily credits (Free tier, including guests) reset every day at midnight UTC. Monthly credits (Pro & Business) reset on your billing cycle date.

Note: With 1 credit per 50 MB, RAW files under 50 MB cost 1 credit each. Pro users can convert 10,000 RAW files per month.
