Prepare a Photoshop Design for JPG Export

A Photoshop document (PSD) can contain multiple layers, masks, text objects, effects, adjustment layers and transparency. A JPG is a flattened raster image. Converting a PSD to JPG is therefore an export step: it creates one viewable image from the visible design rather than preserving the editable layer structure. This can be useful when a client, colleague, marketplace or upload form needs a regular JPEG instead of an Adobe Photoshop project file.

Important compatibility note for this page: the current TinyImageResizer PSD-to-JPG route accepts `.psd` in its file picker, but its shared converter tries to load the selected file as a normal browser image and draw it to a canvas. The application does not currently bundle a PSD parsing library in this conversion path. Mainstream browsers do not natively decode PSD documents as ordinary image files, so a PSD upload may pass the file picker and then fail during image loading. This route should not be promoted as a reliable, working PSD converter until a PSD decoder is added and tested.

A real PSD converter must read the Photoshop file structure, locate the composite image or reconstruct the visible result from the document data, then write the rendered pixels as a JPEG. The PSD may contain many layers, but JPG can store only a flattened image. The result therefore cannot be used to edit the original layer stack. It is a separate output for viewing, sending, posting or uploading.

A reliable converter also needs to account for transparency, document dimensions, colour mode, bit depth and unsupported Photoshop effects. Transparent areas must be filled with a background colour because JPEG does not support an alpha channel. A document saved without a compatible flattened composite may require layer reconstruction, and some blending modes, layer effects or adjustment features can be rendered differently by a third-party parser.

The current TinyImageResizer route does not perform those PSD-specific decoding steps. It is based on the generic browser image conversion component used by the WebP, GIF and SVG routes. Selecting a PSD file is not the same as successfully decoding its internal Photoshop structure. Until that functionality is implemented, use an image editor or a PSD-aware converter to export a flattened image, then validate the output separately.

This workflow describes how to create a valid JPG from a PSD. The current TinyImageResizer PSD route does not yet implement the first PSD-decoding step, so it should not be represented as an end-to-end converter until the decoding issue is fixed.

PSD is designed for editable image projects. It can preserve independent layers and other Photoshop-specific information that lets a designer move objects, alter text, update colours or revise effects later. JPG is designed for sharing a finished raster image. It is broadly supported by browsers, office software, phones and online services, but the compressed image does not contain the editable PSD layer structure.

Use PSD when the design is still being worked on, when you need to revise a component or when another designer needs access to the layer stack. Use JPG when the artwork is finished and needs to be attached to an email, placed in a document, uploaded to a listing or displayed by a service that does not accept PSD. Keep both files whenever future revisions are possible.

Flattening combines the visible layers into one rendered image. It is not the same as deleting the layers from your original project if you export a copy correctly. Before exporting, check that hidden layers are intentionally hidden and that text, logos, shadows and other effects look right. If you flatten the only copy and save over it, you may lose the ability to edit each element separately.

The current TinyImageResizer conversion component fills a white background for JPG exports and applies a fixed JPEG quality of 92 percent when it successfully receives a decodable image. It does not provide PSD layer selection, blending-mode controls, colour management or an export-quality slider.

A browser's image element can display common raster formats such as JPEG, PNG, GIF and WebP, and it can render SVG.

PSD is a layered editing document rather than a standard browser image format. The current route filters the file name by the `.psd` extension, but the shared processing code creates a browser `Image` object and waits for it to load. Without a PSD decoder, that load can fail. This means a user may see the PSD file in the queue but still receive no valid JPG result.

A fix requires a parser designed for PSD files, such as a suitable client-side PSD decoding library, or a server-side image-processing pipeline configured to read Photoshop files. The parser should be tested with layered PSDs, flattened composites, transparency, large canvas sizes, text layers, masks, blend modes and colour profiles. It should also expose a clear error message when a PSD feature cannot be reproduced faithfully.

For the generic image conversions that successfully decode, TinyImageResizer uses browser image rendering and canvas export. That local processing model does not make the current component a PSD parser. The PSD route should not claim that it securely converts any PSD document merely because the file is selected in a browser. A separate external PSD application may process the file locally or through its own service; review that application's privacy details before using it for confidential designs.

Keep an untouched copy of the layered PSD and export only a working copy. When a design contains client artwork, product plans or unreleased branding, use an approved application and storage location. Do not rely on a failed or partial browser preview as proof that all layers were read.

Before describing the page as a working PSD-to-JPG tool, implement and test PSD decoding. Confirm that the converter can read the visible composite from representative files, flatten the correct layer result, preserve the intended dimensions, handle transparent areas and generate a valid JPEG. Add an error message for unsupported PSD versions or features, and test large documents so the browser does not become unresponsive. The tool should only claim the exact range of PSD variants that its parser actually supports.

Until the PSD decoder is in place, use this page as a compatibility and export guide rather than promising that an uploaded PSD will convert successfully. A valid exported JPG can still be made with a PSD-aware editor, and a future version of TinyImageResizer can support direct conversion once the missing parsing layer is implemented.
