Any Android phone with Chrome can merge PDFs without installing an app

Merging PDF files on Android doesn't require downloading a separate app. You can combine multiple PDFs into one directly in Chrome using KhanxTools — free, no signup, no watermarks.

Why Merge PDFs on Android?

How to Merge PDF on Android — Step by Step

  1. Open Chrome on your Android phone
  2. Go to khanxtools.com/tools/merge-pdf
  3. Tap "Select PDF Files"
  4. Choose your PDFs from your Downloads, Google Drive, or any folder
  5. All selected PDFs will appear on screen — you can drag to reorder them
  6. Tap "Merge PDF"
  7. Tap "Download" to save the merged PDF to your Android device

💡 Tip: You can merge up to 20 PDFs at once. The order you select them is the order they'll appear in the merged file — but you can always rearrange by dragging after selecting.

How to Reorder PDFs Before Merging

After selecting your files, each PDF appears as a card on screen. To change the order:

This lets you arrange your documents in any order before combining them.

Does It Work on All Android Phones?

Yes — KhanxTools works on any Android phone running Android 7 or later with Chrome or any modern browser. Tested on Samsung Galaxy, Xiaomi, OnePlus, Oppo, and other Android brands.

Is My Data Safe?

Your files never leave your device. KhanxTools uses client-side processing — all merging happens directly in your browser using JavaScript. No PDF is ever uploaded to a server.

Pro tip: After merging, share the combined PDF directly from Chrome's download notification. Tap the notification and choose "Share" to send it via WhatsApp, Gmail, or Telegram instantly.

How to Merge PDFs from WhatsApp on Android

If someone sent you PDFs via WhatsApp that you want to merge:

  1. Open WhatsApp and find the PDFs
  2. Tap each PDF → tap the download icon to save to your phone
  3. Open Chrome and go to KhanxTools Merge PDF
  4. Select the downloaded PDFs from your Downloads folder
  5. Merge and download the combined file

Can I Merge PDFs with Images on Android?

Yes — KhanxTools merges PDFs regardless of their content. Text, images, tables, and mixed-content PDFs all merge correctly. If you have image files (JPG, PNG) you want to combine with PDFs, use KhanxTools Images to PDF first to convert the images, then merge all your PDFs together.

How Long Does Merging Take on Android?

Merging typically takes 5–30 seconds depending on:

For most merges (under 50MB total), expect about 10 seconds.

Merging PDFs on Android: Your Options

Android doesn't have a built-in PDF merge feature like iOS does, but there are several convenient ways to combine PDFs on any Android device:

Method 1: KhanxTools in Chrome (No App Install)

  1. Open Chrome on your Android device
  2. Go to khanxtools.com/tools/merge-pdf
  3. Tap Upload PDFs — select files from Downloads, Google Drive, or any file location
  4. Drag to reorder if needed
  5. Tap Merge PDFs
  6. The merged PDF downloads to your Downloads folder

This approach requires no app installation, processes files locally in your browser, and works on any Android device with Chrome.

Method 2: Google Drive (Built-In)

Google Drive lets you print PDFs to a new merged PDF:

Files already in Google Drive can be selected directly during upload

  1. Upload all PDFs to Google Drive
  2. Open the first PDF
  3. Tap the three-dot menu → Print
  4. Select Save as PDF
  5. Repeat for each PDF — then merge the resulting files with KhanxTools

This method isn't truly a one-step merge but can help if your files are already in Drive.

Method 3: Files by Google App

Files by Google has basic PDF tools in newer versions:

  1. Open Files by Google
  2. Long-press the first PDF
  3. Select additional PDFs (tap each to add to selection)
  4. Look for a merge/combine option in the actions menu

Availability varies by Android version and device. If it's not present, use KhanxTools instead.

After Merging: Reorder Pages If Needed

If the page order in your merged PDF isn't right, open the KhanxTools Organize PDF tool in Chrome, upload the merged file, and drag page thumbnails to the correct positions.
