Android vs iPhone for PDF Conversion

iPhone has a slight edge with the “Pinch to PDF” trick being universally available across all iOS apps. On Android, Google Photos is the best built-in option, but it requires selecting “Save as PDF” in the print dialog (which many users don’t know about).

Both platforms get the job done. The methods above make it straightforward — no extra apps required for basic use.
