How Anyfile's Photoshop Viewer Works
Photoshop viewer: explore supported file formats, viewing limits and open-source credits. Your files are never uploaded.
Viewing architecture
The viewer validates the PSD or PSB header, decodes the saved composite in a dedicated Worker and presents it in a zoomable canvas without uploading the document.
- 1A bounded signature probe validates the format version, dimensions and core header fields.
- 2ag-psd decodes the composite while layer image payloads and linked files stay skipped.
Main limitations
- — Layers cannot be toggled or edited.
- — Files over 256 MiB, composites over 64 Mi pixels and some uncommon Photoshop features are unsupported.
