WHY CONVERT

Why convert RW2 to WEBP

01

Significantly smaller files

RW2 is a lossless format that prioritizes fidelity over size. Converting to WEBP introduces modern compression that typically reduces file size by an order of magnitude with no perceptible difference at normal playback or viewing.

02

Broader cross-platform support

WEBP is accepted by a wider range of image viewers, editors, and content systems than RW2. The conversion removes a recurring compatibility friction without changing what the file actually contains.

03

Lower storage and bandwidth cost

WEBP files are typically smaller than their RW2 counterparts, which reduces hosting, transfer, and storage costs at scale. The savings compound when serving the same content to many recipients.

QUALITY & FIDELITY

Quality and fidelity

  • Lossless source to lossy target: expect a small, irreversible quality loss.
  • Target supports alpha but the source has none, so the output is fully opaque.
  • Metadata (EXIF/tags) is preserved where the source provides it.
  • WEBP can be lossy or lossless — switch modes for pixel-perfect output if needed.
