  1. How to backdate PDF files

  2. FILES CAN LOSE DATA When your files and documents get corrupted or catch a virus, it is possible that these files can still keep their content but lose their metadata.

  3. CAN YOU PUT IT BACK? But how do you put back creation dates? Even if you save and convert a Word file into a PDF, the current date automatically becomes its creation and modified date.

  4. SOLUTION: BACKDATE One possible solution is to backdate your computer’s time (system time) manually then save it as a new document by hitting “save as PDF.” When this is done, the document is converted into a PDF and will automatically take the date from your computer’s system then record these to the file as its creation date.

  5. How to put back the date on your PDF Change date and save Disable Internet Time Computer settings Go to your computer’s Control Panel then click Click and Region then select Date and time On the new window, click the tab on top that indicates “Internet time” then untick the “synchronize with internet server” from the advanced settings Change the time on the Date and Time tab and click OK. Open your Docx / PPT / Excel file then click “Save as PDF” then click Save. 1 2 3 5

  6. NOTE TO SAVING: Make sure to pick SAVE AS and not SAVE because if you pick the latter, it will only save the existing file, update the “modified date” and not the “creation date.” CHECKING You can only check the date when it was converted into PDF by checking its properties CREATION DATE Once the MS Word or Office document is saved as PDF, the file is converted and created as a new document in the hard drive. Therefore, the creation date will base on the day the author “created” it as a PDF and disregards dates from the source application.

  7. How to check dates on a PDF file First Right-click on the document from your document folders Second Select “Properties” Third A new window will appear. This will show you data about the PDF file but not prior to that. This also includes the date it was created, modified and accessed. 7
