Why Convert PSB to AVIF?
This conversion comes up whenever you need high-efficiency images for fast-loading modern websites instead of extremely large or high-resolution layered Photoshop projects. PSB and AVIF serve genuinely different purposes, so moving between them isn't just a formality.
AVIF is a modern AV1-based compressed image format, built around high-efficiency images for fast-loading modern websites. Converting from PSB — built around extremely large or high-resolution layered Photoshop projects instead — closes that gap.
Our engine reads a file built around extremely large or high-resolution layered Photoshop projects and rebuilds it aiming to preserve this: noticeably smaller files than PNG or JPG at comparable quality — rather than producing a generic, lowest-common-denominator result.

Frequent Questions
Can I convert the file back from AVIF to PSB afterward?
Only what AVIF actually carries can come back — anything specific to PSB's role in extremely large or high-resolution layered Photoshop projects that didn't survive the original conversion won't reappear.
Why does AVIF 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 AVIF is aimed at high-efficiency images for fast-loading modern websites. Neither format is "better," they just fit different parts of a workflow.
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.
Is AVIF objectively better than PSB?
Not objectively — AVIF is better specifically for high-efficiency images for fast-loading modern websites. For extremely large or high-resolution layered Photoshop projects, PSB is still the right tool; that's exactly why both formats exist.
Why would I need AVIF instead of just keeping PSB?
Mainly when your workflow specifically calls for high-efficiency images for fast-loading modern websites — that's AVIF'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.
