P: PS 27.5 & Beta Mark Tiffs files as "saved" after using 'Export As'

Yes, I can confirm this problem, too. It appears to affect TIFF, PNG, and JPEG — but not PSD.

The bug was present in v27.0 and is the same in 27.5. macOS 26.4.

It’s quite a serious bug, if you ask me.

After making a change in the document, then using Export As, the document becomes marked as saved. Fortunately, it’s marked as saved falsely. But it causes a whole lot of confusion. 

For example, if you close this falsely-marked-as-saved document, there won’t be a dialog asking to save changes. However, the changes are not in fact saved (again, fortunately). When you open the document again, it opens in its original, unchanged state.

Also, after Export As, you can also Revert this falsely-marked-as-saved document. In which case, the document becomes marked as unsaved (also falsely). Because this state is the actual saved state of the document, and not the state that was reported as saved after Export As. So even if you click Don’t Save when closing the document, it will (yet again, fortunately) retain this actual saved state instead of reverting to the fake saved state.

Hope it makes sense.

Also reproducible on Windows 11 with both Photoshop 2026 (27.5) and the 26.7 Photoshop Beta.

I’m am able to reproduce the issue here on macOS Sonoma 14.8.5 with Photoshop 2026 (27.5)

That is, when saving a tiff file with unsaved changes using File>Export As, the file is indicated as

saved, which should only happen if the file is saved to another file format that supports layers,etc like psd, psb or tiff.

So far, it only seems to occur with .TIFF files when using File>Export As set to any format.

Doesn’t happen when using File>Save As or File>Export>Save for Web.

I also tried under Photoshop 2026 Settings>File Handling turning on/off Enable Legacy “Save As”, but that didn’t make any difference.

So? any news?  ​@Sameer K 

Do you use Export As or Save For Web? There’s a difference between them.

• With Export As, the original file can just be closed out after the export, without any saving. Just hit the X to close it, that’s it.
• With Save For Web, export metadata are written to the file header, which counts as a file change. So you get a dialog prompt to save or not before closing out.
• With a regular Save As to a different file format, it behaves like Export As; just close out the original because it will not be altered in any way. Again, just hit the X and that’s it.

Either way, there is never any need to “fake an edit” to close out. Just close it.

Hey, @Perfect_Nemus. Welcome to the Photoshop Community. I'll help you figure this out. Based on the description, this behavior could be expected, but I’ve been unable to reproduce it. 

Please share a video of the issue and the system info from Photoshop Help > System Info. Copy and paste it into a text document, then upload and attach it here.

Please test and confirm if Photoshop (Beta) has an issue. You can get Photoshop (Beta) from the Creative Cloud > Apps tab > Beta Apps section. 

Thanks!
