PSD is a image format: it preserves non-destructive editing layers, masks, adjustment layers, and smart objects in a proprietary Adobe format. TIFF is a image format that stores high-depth raster images with optional lossless LZW compression and supports multiple pages in a single file. This conversion changes the file's encoding, compression method, and supported feature set. The output is pixel-accurate: no further quality is lost beyond what the source already encoded. Converting between these two formats is common when the source application does not support TIFF natively or when the target platform only accepts TIFF. 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.
