"Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch."

JNG to PPM Conversion: FAQ

What are JNG files?

JNG (JPEG Network Graphics) is an offshoot of the PNG/MNG family that packages a JPEG-compressed RGB image together with a lossless PNG-style alpha channel, giving you full transparency at smaller file sizes than an equivalent PNG. It uses the same chunked structure as PNG, making it easy to embed metadata or animation cues when paired with MNG. Despite its clever hybrid design, mainstream browsers and tools never embraced JNG, so it remains a niche format overshadowed by PNG, WebP, and AVIF.

What are PPM files?

PPM or Portable Pixelmap files are image files included in Netpbm, an open source graphics program. The other widely used Netpbm formats are PGM (Portable Graymap) and PBM (Portable Bitmap). All three are image formats and are sometimes called collectively PNMs (Portable Anymap format). While PGMs contains grayscale images, PPMs include color images and they represent intermediary files used in the conversion of less known formats using the Portable Bitmap Utilities. PPM files are mostly operated on UNIX and Intel-based platforms.
