ODT is a document format: it stores text and formatting as a zipped ODF XML archive, the ISO-standardised open alternative to DOCX. WEBP is a image format that supports both lossy and lossless encoding with transparency and animation, typically 25-35% smaller than equivalent JPEG or PNG files. This renders each page as a raster image, making the content viewable without a document reader. Each page is rendered at the specified DPI and saved as a separate image; text in the output is no longer selectable. Converting between these two formats is common when the source application does not support WEBP natively or when the target platform only accepts WEBP. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
