WebP Image (WEBP) supports both lossy and lossless encoding with transparency and animation, typically 25-35% smaller than equivalent JPEG or PNG files. QuickTime Movie (MOV) packages video and audio in Apple's QuickTime container, which can hold ProRes, H.264, or HEVC tracks. This conversion changes the file's encoding, compression method, and supported feature set. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. The result is a standard MOV file readable by any compatible application. 1converter handles WEBP-to-MOV 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.
