🤖 Merge PDFs in Chrome →Google Drive has a hidden PDF merge feature that most Android users don't know about. It uses the Print function to combine PDFs — it's a workaround rather than a dedicated tool, but it works without any extra app and your files stay within Google's ecosystem.
Best for: Users who already have their PDFs saved in Google Drive and want to stay within the Google ecosystem. Android 8+
Open the Google Drive app and make sure both PDFs you want to merge are uploaded and accessible. Tap the + button to upload from your phone if needed.
Tap the first PDF to open it in Drive's built-in viewer.
Tap the ⋮ icon in the top right, then tap Print. This opens Android's print dialog.
In the print dialog, tap the printer dropdown at the top and select Save as PDF. Tap the PDF icon to save. Repeat for the second PDF.
This Google Drive method is best for converting and preparing individual files. To combine them into one, use Method 1 above with the Chrome browser tool — it gives you full control over the merge order.
Files by Google is a file management app developed by Google that comes pre-installed on Pixel phones and is available free from the Play Store. On some devices it offers basic PDF management — though its merge capability is limited compared to the browser method.
Best for: Google Pixel users who want a quick offline option for simple merges. Pixel & supported devices
Find and open the Files by Google app. On Pixel phones it's pre-installed. On other Android phones, install it free from the Play Store — it's made by Google and has no ads.
Tap Browse at the bottom, then navigate to the folder containing your PDF files — usually Downloads or Documents.
Long-press the first PDF until it shows as selected (blue checkmark). Then tap each additional PDF you want to include.
Tap Share and choose Chrome. The files will open in a new Chrome tab. From there, use the RapidTools merger at rapidtools.online/merge-pdf to complete the merge with full order control.
