Converting a handful of NEF files one at a time in an online converter is fine for a couple of images and genuinely painful for anything resembling a real shoot. If you want to convert nef to jpg for more than a handful of files, batch conversion with the right settings is the actual answer, and it is free to do properly without giving up quality along the way.
Why Single-File Converters Waste Time
Web-based single-file NEF converters require uploading one RAW file at a time, waiting for processing, and downloading the result, then repeating for every single frame in a shoot. For a hundred-plus frame session, that is an afternoon lost to a task that should take minutes. Single-file tools also frequently apply generic default processing (exposure, white balance, sharpening) with no batch-wide control, meaning inconsistent results across a set of images that should look like one coherent shoot.
Batch Conversion with Quality and Resize Settings
Proper batch conversion applies the same export settings, JPEG quality level, resolution or resize target, color profile, across an entire folder of NEF files in one pass. The two settings that matter most for quality: JPEG quality (aim for 85 to 95 out of 100 for client delivery; anything much lower introduces visible compression artifacts, especially in skies and skin tones) and resize dimensions (only downsize if you have a specific delivery requirement; unnecessary downsizing throws away resolution you cannot get back). imagic's RAW processing, via its own built-in RAW engine, handles NEF among its supported formats (alongside CR2, CR3, ARW, RAF, ORF, RW2, DNG, and PEF) and exports to JPEG or TIFF with batch settings applied across a whole folder at once, plus AI culling first so you are not converting frames you will delete anyway.
When to Use TIFF Instead of JPG
JPEG is a lossy format, fine for final delivery and web use, but each re-save introduces additional compression loss. If a file might be re-edited later, printed large, or needs to preserve maximum quality for archival purposes, export to TIFF instead: it is lossless (or minimally compressed depending on settings) and holds up far better through multiple rounds of editing. A reasonable rule: JPEG for anything going straight to a client gallery or the web, TIFF for anything that might get reopened and re-edited down the line.
Common Artifact Mistakes
The most common quality mistake is setting JPEG quality too low to save file size, which introduces visible blocky artifacts especially in smooth gradients like skies and out-of-focus backgrounds. The second most common mistake is repeatedly re-exporting the same file as JPEG through multiple editing rounds, compounding compression loss each time, when the source RAW should be re-exported fresh instead. The third is resizing down for a specific delivery need and then trying to use that same downsized file for a different, larger purpose later, when going back to the original NEF and re-exporting at the right size would have preserved quality.
A Practical Batch Workflow
Import the full NEF folder, run AI culling to find the actual keepers rather than converting everything, set a consistent style or one-click look across the batch, then export at 85 to 95 JPEG quality (or TIFF for anything needing further editing) in one pass across the whole shortlist.

Frequently asked questions
What JPEG quality setting should I use for client delivery?
Somewhere around 85 to 95 out of 100 typically balances file size and visible quality well for gallery and web delivery; go higher if file size is not a constraint.
Should I convert every NEF file in a shoot or only the keepers?
Only the keepers, ideally after culling. Converting an entire unculled shoot wastes time and storage on frames that will be deleted anyway.
Does converting NEF to JPG lose quality even at high settings?
JPEG is always somewhat lossy, but at 90 or higher the difference is generally not visible to the eye; TIFF is the better choice if you need a lossless intermediate file.
