Format Overview & Applications

Large Photoshop artwork may be cumbersome to distribute for a simple approval; the PDF supplies a view copy, but the PSB remains the document to revise.

Technical Specifications & Codec Breakdown

The PSB reader skips its 64-bit-length layer-and-mask section, then decodes the merged composite section; only the composite image is sent on to the PDF page.

OS & Browser Compatibility

PSB-aware Photoshop workflows are needed to revise its layers; production staff can view the one-page PDF using standard document readers.

Useful info

Confirm the merged image is current before saving the PSB; the converter does not composite individual layers itself.

Format Comparison & Technical Specifications

For a large print mural, a 12000×8000 PSB composite maps to an 80×53.3 inch PDF page at 150 dpi.

Frequently Asked Questions

Does the PDF retain the PSB layer structure?

No, it is built from the PSB merged composite pixels after the layer section is skipped. The PDF has no PSB layer controls.

Can I use the PDF to check the full mural dimensions?

Yes, the page uses the decoded composite dimensions at 150 dpi; 12,000 pixels across corresponds to an 80 inch page width.
