Questions about Merge PDF
Will interactive forms and signatures remain valid?
Do not rely on merging to preserve interactive features or digital-signature validity. Check the output before use and keep the originals.
Where are my converted files saved?
Use Download to save a copy, or Open file to preview the result. Results are held in the current browser tab; they are not kept in a cloud file history. Open the saved file to check it before closing the page.
What should I do if a conversion fails?
Read the error beside the converter, retry the failed file if offered, and use Give feedback or contact beta support. Keep your original file. The beta may still have device-specific issues.
