Adobe Photoshop Document (PSD) preserves non-destructive editing layers, masks, adjustment layers, and smart objects in a proprietary Adobe format. Bitmap Image (BMP) stores uncompressed pixel data in a simple row-by-row grid, resulting in large file sizes but zero quality loss. This conversion changes the file's encoding, compression method, and supported feature set. Colour profiles and orientation metadata are preserved in the output. The result is a standard BMP file readable by any compatible application. 1converter handles PSD-to-BMP 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.
