Adobe Photoshop Document (PSD) preserves non-destructive editing layers, masks, adjustment layers, and smart objects in a proprietary Adobe format. Electronic Publication (EPUB) packages HTML, CSS, and images in a zipped OPS container as an ISO-standardised ebook format that reflows text to fit any screen width. 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 EPUB file readable by any compatible application. 1converter handles PSD-to-EPUB 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.
