How PSB turns into JPG: pixel decoding and image re-encoding

Photoshop large document data for canvases or file sizes beyond ordinary psd limits is decoded into a working pixel canvas first, then written back out under JPG's own color and compression model. Dimensions can stay exactly the same even as encoding, metadata, and fine detail change underneath. PSB parsing extends the Photoshop document model to very large canvases while retaining layers, masks, channels, effects, smart objects, and color data. JPG delivery writes opaque, lossy photographic pixels; quality must be judged around high-contrast edges, gradients, fine texture, orientation, and repeated-encode damage.

Decoded canvas - Photoshop Large Document data for canvases or file sizes beyond ordinary PSD limits. Written image - Lossy JPEG pixels tuned for photographic detail and near-universal compatibility.

When to actually choose PSB to JPG

Choose JPG when its particular balance of compatibility, alpha, animation, and file size matches the destination better than PSB.

What changes between the PSB model and the JPG deliverable

JPG is a lossy destination, so judge the converted image, motion, or sound directly instead of trusting matching dimensions or file size.
Metadata handling differs between PSB and JPG; do not assume every application-specific field carries across untouched.

PSB source facts versus JPG output requirements

PSB

What can fail when PSB raster image is interpreted

Many PSD-compatible tools do not support PSB, and a flattened export loses large-document layers, masks, and smart objects.

JPG

What JPEG image cannot safely promise

Every additional JPEG encode adds more ringing and blocking around edges, and any transparency has to be flattened to an opaque background first.

ENGINE

How the JPG writer handles this route

The writer builds lossy JPEG pixels tuned for photographic detail and near-universal compatibility and labels the result as image/jpeg. The receiving application - Not the extension alone - Is the final compatibility test.

How to confirm the converted JPG actually works

BEFORE

Record the PSB evidence before conversion

Verify canvas dimensions, bit depth, layer count, masks, type, smart objects, and saved composite in a PSB-aware editor.

AFTER

Test the JPG file in its receiving workflow

Compare faces, gradients, and high-contrast edges at full display size, and confirm transparent areas were flattened the way you expect.
