Photoshop will not save as JPEG: check Save a Copy and the format list

Identify what is actually failing

A missing JPEG option and an error after pressing Save are different problems. Note which command you used, the document's mode and bit depth, and whether the destination is local or cloud storage.

Make a small, ordinary RGB test document and try the same save command. If JPEG is available there, focus on the original document's characteristics. If it is absent everywhere, inspect the application settings and version before editing the artwork.

Use the copy workflow first

Save the editable master, then choose File > Save a Copy. Select JPEG if it is offered, choose a distinct output name and location, and inspect the subsequent quality options.

Adobe documents this workflow for producing a flattened copy while leaving the original open and unchanged. You should not need to destroy the master document's layers just to create a deliverable. After saving, reopen the JPEG itself: looking at the still-open PSD is not a check of what was written to disk. Adobe's saving workflows

Check whether the format was hidden

In versions that include Edit > Customize Save Dialog File Formats, open that dialog and check whether JPEG is enabled. The selected formats control what appears in Save As and Save a Copy.

If your installation does not have that command, skip this step. Do not search for a similarly named third-party plug-in or reset preferences solely because a newer documented menu is absent. Enabling a format in the list also does not remove that format's technical limitations. Adobe's format-list controls

Check mode, bit depth, and the delivery requirement

Adobe documents JPEG saving for RGB, CMYK, and grayscale images. JPEG stores 8-bit image data; Photoshop can lower bit depth when saving a 16-bit image to JPEG. That means a 16-bit master does not automatically require manual destructive conversion first.

For another mode or an HDR workflow, make a separate document copy before conversion. Confirm the client's requested color space and output format. Do not turn a print master into RGB merely because a website needs a different delivery version.

JPEG also uses lossy compression. Choose another format if the requirement is editable layers, transparency, or preservation of higher-bit-depth image data. Renaming an extension to .jpg does not convert the file.

Check the actual saved result

Open the output and inspect its pixel dimensions, background, fine text, and visible compression at a useful zoom. Keep the output filename distinct from the master so subsequent edits do not target the wrong file.

If JPEG is selectable but saving fails, collect the exact error and consult Adobe Support for a saving problem. Include the version, mode, dimensions, destination type, and whether the small test document succeeded. This article is documentation-reviewed, not a hands-on test.
