Is PDFWix safe for confidential PDFs on Android?

Yes. The merge runs in Chrome on your phone using WebAssembly — your PDFs never reach our servers. You can verify in Chrome DevTools (chrome://inspect via USB to a desktop) that no upload happens during merge.

Will the merged PDF work on iPhone, Mac, and Windows?

Yes. The output is a standard PDF that opens in any reader — iOS Files, macOS Preview, Windows Edge, Adobe Reader, anything. PDFWix produces clean, spec-compliant PDF 1.7 output.

Frequently asked questions

Can Google Drive merge PDFs on Android?

No. Google Drive on Android has no merge feature and never has. Many blog posts claim otherwise — they're wrong or describing the desktop Workspace 'Combine files' option, which isn't on mobile. Use PDFWix in Chrome for a free in-browser merge.

What's the best free PDF merger for Android in 2026?

PDFWix in Chrome (or Firefox/Samsung Internet). It's free, has no daily cap, requires no install, and runs the merge in your browser so your files stay on your device. Adobe Acrobat's Android app gates merge behind a $9.99/month Pro subscription.

Do I have to install an app to merge PDFs on Android?

No. PDFWix runs entirely in your browser — no Play Store install, no permissions to grant. This is also safer than most third-party PDF apps, which often request 'all files' storage permission.
