WebP Image (WEBP) supports both lossy and lossless encoding with transparency and animation, typically 25-35% smaller than equivalent JPEG or PNG files. DVR file (DVR) stores data in the DVR format. This embeds the raster image inside a document container, fixing its dimensions on the page. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. The result is a standard DVR file readable by any compatible application. 1converter handles WEBP-to-DVR conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.
