Why not just install a PDF app from the Play Store?
Most PDF merger apps on the Google Play Store have real drawbacks: they add watermarks unless you subscribe, request invasive permissions (contacts, camera, storage access for all files), bundle aggressive ads, or upload your documents to their servers. Finding a trustworthy, genuinely free option in the Play Store is harder than it looks.
The zero-install alternative: use Chrome. Every Android phone has Chrome installed. ihatepdf.cv/merge-pdf runs the entire merge operation inside Chrome using WebAssembly — no app to install, no Play Store permissions, no watermark, and your PDFs never leave your phone.
How to merge PDFs on Android using Chrome
- Open Chrome on your Android phone (Firefox or Samsung Internet also work)
- Go to ihatepdf.cv/merge-pdf
- Tap Select PDFs — this opens the Android file picker
- Navigate to your PDFs (they can be in Downloads, Google Drive, or internal storage)
- Tap each PDF to select it, or long-press for multi-select mode
- Tap Open — the files load into the merger
- Drag the page thumbnails to arrange files in the order you want
- Tap Merge PDFs — processing takes 5–20 seconds on phone
- Tap Download — the merged file saves to your Downloads folder
Selecting multiple PDFs in Android's file picker
Android's file picker behavior varies by manufacturer, but on most phones:
- Long-press the first PDF file to enter selection mode
- Tap each additional PDF to add it to the selection
- Tap Open or the checkmark icon to confirm
On Samsung devices with the Samsung My Files app, you can also tap the three-dot menu and use "Select" to enter multi-select mode.
Accessing PDFs from Google Drive on Android
If your PDFs are stored in Google Drive, you have two options:
- Option A (direct): When the ihatepdf file picker opens, navigate to "Google Drive" — it appears as a location in the Android file picker if you're signed in. Select PDFs directly from Drive without downloading them first.
- Option B (download first): Open the Google Drive app, tap the three-dot menu next to each PDF, and tap "Download" to save copies to your Downloads folder. Then select them from Downloads in the file picker.
Merging PDFs from WhatsApp, email, or messaging apps on Android
When PDFs arrive via WhatsApp or Gmail, save them to your Downloads folder first:
- WhatsApp: Open the document, tap the download icon (arrow pointing down), then find it in WhatsApp's "WhatsApp Documents" folder or your Downloads folder
- Gmail: Open the email, tap the download icon on the PDF attachment, which saves it to Downloads
- Telegram: Open the file and tap the download icon — it saves to Telegram's download folder or your Downloads folder depending on settings
Once saved locally, they're available in the file picker when you tap Select PDFs in ihatepdf.
Where does the merged PDF save on Android?
Chrome on Android downloads files to your Downloads folder. You can access it through:
- The Files by Google app (or your manufacturer's file manager)
- Chrome's download menu: tap the three-dot menu → Downloads
- Google Drive if you have "Upload downloads to Drive" enabled
From the Downloads folder, use the share icon to send the merged PDF via Gmail, WhatsApp, Telegram, or any other app installed on your Android phone.
Frequently asked questions
Do I need to install anything to merge PDFs on Android?
No. Chrome is pre-installed on all Android phones that ship with Google apps. Open Chrome, navigate to ihatepdf, and merge — no installation, no sign-up, no Play Store required.
Will my PDFs be uploaded to the internet?
No. ihatepdf's merger runs locally in Chrome using WebAssembly. Your PDF bytes never travel over the network. You can confirm this by enabling airplane mode after the ihatepdf page loads — the merger still works with no internet connection.
Does the merged PDF have a watermark?
Never. ihatepdf does not add watermarks to any output file.
Can I merge PDFs on Android without Google Chrome?
Yes. Firefox for Android, Samsung Internet, and Brave browser all support WebAssembly and work with ihatepdf. Open your preferred browser and navigate to the same URL.
How large a PDF can I merge on an Android phone?
The practical limit is your phone's available RAM. Budget Android phones with 3–4GB RAM typically handle PDFs up to 50–70MB total. High-end phones with 8–12GB RAM can handle much larger files. Close other apps before merging large PDFs to free up memory.
