Comma-Separated Values (CSV) stores tabular data as plain text with one row per line and field values delimited by commas, readable by any spreadsheet or database tool. Adobe Photoshop Document (PSD) preserves non-destructive editing layers, masks, adjustment layers, and smart objects in a proprietary Adobe format. 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 PSD file readable by any compatible application. 1converter handles CSV-to-PSD 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.
