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

Lossy jpeg-compressed pixels optimized for photographs and broad compatibility is decoded into a working pixel canvas first, then written back out under PSD's own color and compression model. Dimensions can stay exactly the same even as encoding, metadata, and fine detail change underneath. JPEG decoding applies orientation and color interpretation to already quantized image blocks; each later lossy write starts from those decoded pixels rather than the camera original. 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.

Canvas decoded from lossy JPEG-compressed pixels optimized for photographs and broad compatibility. Image written as a Photoshop document that can contain layers, masks, channels, type, and adjustment data.

The delivery decision for this JPG to PSD route

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

What changes between the JPG model and the PSD deliverable

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

Reading JPG correctly and satisfying what PSD expects

JPG

What can fail when JPEG image is interpreted

Repeated encoding introduces ringing or blocks, and transparent areas must become opaque.

PSD

What PSD raster image cannot safely promise

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

ENGINE

How the PSD writer handles this route

The writer builds a Photoshop document that can contain layers, masks, channels, type, and adjustment data and labels the result as image/vnd.adobe.photoshop. The receiving application - Not the extension alone - Is the final compatibility test.
