Batch Settings
HDR data will be tone-mapped
Your NEF file may contain HDR (High Dynamic Range) data. GIF only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Some metadata may not survive
Your NEF file may contain EXIF, MakerNote, XMP metadata. GIF has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.

Frequently Asked Questions
Why won't my NEF file open?
NEF files may not open if your device lacks the right codec or application. Converting to GIF — a more widely supported format — usually resolves this. GIF supports animation and 256-colour palettes, widely used for short animated clips and simple graphics.
Is it safe to convert NEF to GIF online?
Yes. CocoConvert encrypts your file via TLS, processes it on isolated servers in Germany, and permanently deletes it within 24 hours. Your files are never shared or analysed.
Will I lose quality converting NEF to GIF?
Your NEF file may contain HDR (High Dynamic Range) data. GIF only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost. CocoConvert uses high-quality encoder defaults to preserve as much fidelity as possible.
How large can my NEF file be?
Free users can convert files up to 250 MB each. Pro users get a 5 GB limit per file, and Business API users have custom limits.
Can I convert NEF to GIF on my phone?
Absolutely. CocoConvert works in any modern browser — iOS Safari, Android Chrome, and all desktop browsers. No app required.
