FAQs
Why convert 3G2 to PSB?
Choose PSB as target when the image must remain editable in Photoshop at very large dimensions or layer counts.
What changes when converting 3G2 to PSB?
Convert to PSB when the image must remain editable in Photoshop at very large dimensions or layer counts. It is useful for oversized composites, print backdrops, and complex production artwork.
What should I review after converting 3G2 to PSB?
After conversion, review these destination checks: Open converted output in Adobe Photoshop and verify behavior on real samples; Compare output against the expected depends quality profile; Layer-heavy documents are not efficient consumer delivery formats.
How can I keep quality stable in 3G2 to PSB conversion?
Run representative samples, keep settings deterministic, and monitor these risks: Feature fidelity still depends on what the receiving editor actually implements; Layer-heavy documents are not efficient consumer delivery formats; Validate destination compatibility before large-batch conversion.
