EXIF data exporting with Ph

I need to keep the EXIF ​​data of a TIFF file when converting it to jpeg. Could someone tell me how to do it?

Thanks in advanced.

    You can set whatever resolution you want. Set metadata to All or All except Camera Info and that will be preserved, otherwise its stripped out.

    It can be hard to remember which methods and formats retain resolution or ICC metadata. I just tested and created a table comparing the different methods, options and results:

     

    Photoshop 2024 (25.4.0)
         
    Output Method Resolution Metadata (PPI) ICC Profile
         
    Save/Save As/Save a Copy Resolution Metadata (PPI) ICC Profile
    JPEG Retained Retained
    PNG Retained Retained
         
    Export As Resolution Metadata (PPI) ICC Profile
    JPEG Metadata: Copyright & Contact Info Removed Retained
    JPEG Metadata: None Removed Retained
    PNG Metadata: Copyright & Contact Info Retained Retained
    PNG Metadata: None Retained Retained
         
    Quick Export Resolution Metadata (PPI) ICC Profile
    JPEG Metadata: None Removed Removed
    PNG Metadata: None Retained Removed
         
    Save for Web (Legacy) Resolution Metadata (PPI) ICC Profile
    JPEG Metadata: All Retained Retained
    JPEG Metadata: All Except Camera Info Retained Retained
    JPEG Metadata: Copyright & Contact Info Removed Retained
    JPEG Metadata: Copyright Removed Retained
    JPEG Metadata: None Removed Retained
    PNG Metadata: All Removed Retained
    PNG Metadata: None Removed Retained
         
    Generate Image Assets Resolution Metadata (PPI) ICC Profile
    JPEG Default Settings Removed Removed
    JPEG Custom Configuration File Settings Removed Retained
    PNG Default Settings Removed Removed
    PNG Custom Configuration File Settings Removed Retained
         
    Adobe Camera Raw Save Options Resolution Metadata (PPI) ICC Profile
    JPEG Metadata: All Retained Retained
    JPEG Metadata: All Except Camera & Camera Raw Info Retained Retained
    JPEG Metadata: All Except Camera Raw Info Retained Retained

      Excellent work, Stephen. A very useful summary. I think that Export for web (legacy) gives me more possibilities than the other saving methods.

      I use Save for Web in production, its the most flexible option although highly dated. Set Metadata to All or All Except Camera Info to preserve EXIF.

      I can't use the Save for Web  (legacy)  option, because there the resolution limit is 100 px and to comply with the photo contest protocol they ask  for 254 px resolution. However, thank you.

      It's not 100ppi, the resolution would be totally removed. The 100ppi would come from your viewing software as a default. If there is no resolution metadata, Mac defaults to 72ppi while Windows uses 96ppi (both for legacy historical reasons that are no longer valid).

       

      It is possible to add the missing resolution metadata back into the exported files (Photoshop script for JPEG, Bridge script for JPEG or ExifTool for PNG or JPEG) – however, using save as is easier.

      Save As/Save a Copy includes all metadata.

       

      Export As strips out most metadata (two options, no metadata or only copyright and contact).

       

      Save for Web (Legacy) has more metadata options than Export As.

        Stephen, thanks a lot for your response. The first method (Save as) is the most appropriate. Better than Save for the web because they ask me for a resolution of 254 px and system only allows a maximum of 100. Best Regards.
