Pixel decoding and image re-encoding: how PSB becomes PSD

Converter.now decodes Photoshop Large Document data for canvases or file sizes beyond ordinary PSD limits into a working pixel canvas, then writes that canvas according to PSD's color and compression model. Dimensions may stay constant while encoding, metadata, and fine detail change. PSB parsing extends the Photoshop document model to very large canvases while retaining layers, masks, channels, effects, smart objects, and color data. PSD output aims to retain a Photoshop-style composite and editable layers, masks, channels, effects, text, and color data instead of only one flattened bitmap.

Decoded canvas - Photoshop Large Document data for canvases or file sizes beyond ordinary PSD limits. Written image - A Photoshop document that can contain layers, masks, channels, type, and adjustment data.

Deciding when PSB to PSD is the right conversion

PSD wins this route whenever its specific mix of compatibility, alpha, animation, and file size fits the destination better than PSB does.

What changes between the PSB model and the PSD deliverable

PSD supports alpha transparency that PSB never had, so any transparent areas in the result are newly created, not carried over from the source.
PSD supports an editable object model PSB never had, so structure in the result is newly assigned by the writer, not carried over from the source.
PSB and PSD use different metadata conventions, so application-specific fields should be treated as optional until verified.

Reading PSB correctly and satisfying what PSD expects

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.

PSD

What PSD raster image cannot safely promise

Most non-PSD outputs flatten layers, while unsupported smart objects or effects may render differently.

How the PSD writer handles this route

a Photoshop document that can contain layers, masks, channels, type, and adjustment data is what gets written, labeled as image/vnd.adobe.photoshop. Whether that actually opens depends on the receiving application, not on the file extension.

Checking the PSD result before you trust it

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 PSD file in its receiving workflow

Open the result in the intended editor and inspect layer count, masks, typography, blend modes, and canvas size.
