Why Convert PSB to JXL?
JPEG XL was built around high-efficiency image storage with both lossy and lossless modes, which is precisely the gap PSB leaves open, since it's designed around extremely large or high-resolution layered Photoshop projects instead.
PSB is Photoshop's Large Document Format for very large files, commonly used for extremely large or high-resolution layered Photoshop projects. That focus comes with a real limitation: only opens reliably in Photoshop and a few compatible tools. JPEG XL doesn't share that problem — its strength: better compression than JPEG at equivalent visual quality.
PSB is typically produced by or used with Adobe Photoshop, for extremely large or high-resolution layered Photoshop projects. JPEG XL is expected by newer image tools and some modern browsers instead, for high-efficiency image storage with both lossy and lossless modes — converting bridges that gap.

Frequent Questions
Do I need any special settings before uploading my PSB file?
No special setup is required — upload the file as-is. PSB files meant for extremely large or high-resolution layered Photoshop projects convert most predictably; unusually exported or non-standard files are the most common reason a specific one might need extra attention.
What software works with the converted JXL file?
JPEG XL is used by newer image tools and some modern browsers. If you were working with Adobe Photoshop (which produces PSB), this conversion is the direct bridge between the two.
Is JXL objectively better than PSB?
Not objectively — JPEG XL is better specifically for high-efficiency image storage with both lossy and lossless modes. For extremely large or high-resolution layered Photoshop projects, PSB is still the right tool; that's exactly why both formats exist.
Why does JXL exist as a separate format instead of everyone just using PSB?
Because they're built for different jobs — PSB is aimed at extremely large or high-resolution layered Photoshop projects, while JPEG XL is aimed at high-efficiency image storage with both lossy and lossless modes. Neither format is "better," they just fit different parts of a workflow.
Why would I need JXL instead of just keeping PSB?
Mainly when your workflow specifically calls for high-efficiency image storage with both lossy and lossless modes — that's JPEG XL's whole reason for existing, and PSB isn't built to provide it, since it's focused on extremely large or high-resolution layered Photoshop projects instead.
