Convert SRW to WEBP — Smaller Web Files
A Samsung SRW file is 20–40 MB of RAW sensor data, which is not something you put on a web page. WEBP is the modern answer — smaller than JPG at matching quality and supported by every current browser.

Why Convert SRW to WEBP?
WEBP is typically 25–35% smaller than JPG at matching quality and is supported by every current browser. For a Samsung shooter publishing 20–28 MP frames, that is bandwidth saved on every view. Note that Samsung left the camera business in 2015, so SRW is an orphaned format with no vendor software still being updated — which is exactly why converting matters more here.
How to Convert SRW to WEBP
Upload your SRW file. Up to 50 files per batch, 50 MB each.
KoalaPic decodes the Samsung RAW and encodes WEBP at quality 85 by default.
Download the WEBP, or adjust quality first if you want a smaller file.
Quality Note
WEBP at quality 85 is visually indistinguishable from the JPG equivalent while landing 25–35% smaller. For a 20–28 MP Samsung frame that is a meaningful saving on every page load.
