"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."

ACORN to JP2 Conversion: FAQ

What are ACORN files?

The ACORN file format is associated with Acorn Sprite or RISC OS Sprite and it represents a bitmap image of up to 32 bpp. ACORN images usually store application icons and screenshots, but they can also store multiple images. As the standard file format for storing bitmap images in the RISC OS system, ACORN files are usually found on computers which run this system, such as the Acorn Archimedes. RISC OS was an operating system used in the late 1980s and 1990s, and at the moment ACORN files are considered rare and obsolete.

What are JP2 files?

JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images.
