PSB to PS Converter

PSB (Photoshop Big) is Adobe Photoshop's large-document format, created to overcome the 2GB file size and 30,000-pixel-per-side limits of the standard PSD format. PSB supports files up to 300,000 pixels per side and several times larger in file size, preserving the same layers, masks, channels, and editing data as PSD. It's used almost exclusively for very large, professional design or production files such as billboard art, film compositing, and high-resolution print work.

PSB files open natively in Adobe Photoshop, which automatically switches to the PSB format once a document exceeds PSD's size limits. They can also be opened by other Adobe Creative Cloud applications and select third-party editors with PSB support, such as Affinity Photo, though broad cross-platform support is limited compared to PSD.

PostScript (PS) is a dynamically typed, concatenative page description language developed by Adobe Systems, serving as the predecessor to the PDF format. It describes text and graphics on a page using vector graphics instructions rather than rasterized pixels, making it resolution-independent. A PS file contains a program written in the PostScript language, which is interpreted by a Raster Image Processor (RIP) to generate the print output. It supports distinct imaging models, including Type 1 fonts and color separations, and became the standard for desktop publishing and high-end printing workflows in the 1980s and 90s.

Opening PS files requires software capable of interpreting the PostScript language, as modern OS image viewers do not support it natively. Ghostscript is the standard open-source interpreter used to view and convert PS files. For GUI-based editing and viewing, Adobe Illustrator and CorelDRAW can import PS files. Users can also convert PS files to PDF using tools like ps2pdf (part of the Ghostscript suite) for easier accessibility.
