When Should You Use PSB vs BPG?

PSB vs BPG: Key Differences

• •PSB uses lossless compression while BPG uses lossy compression — this is the fundamental technical difference between the two formats.
• •Moving from PSB (lossy) to BPG (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •How transparency is handled: BPG does not support alpha channels — transparent areas in the source will become opaque.
• •File sizes: PSB files typically range Can exceed 2GB and BPG files 30-50% smaller than JPEG at same quality.
• •Primary audience: PSB is built for large-format graphic design, billboard artwork scenarios, while BPG focuses on web images with superior compression — pick the format that matches your output requirement.
