Why This Matters
What Is a PDF Merge Tool?
Doing this from a phone often means downloading yet another app just for one task. On Android, My PDF works directly in Chrome or any other mobile browser, so you can handle it from your phone without adding another app to your home screen.
A PDF merge tool combines two or more separate PDF files into a single document, in the order you choose, without altering the content, formatting, fonts or images of any individual page. Instead of sending someone five separate attachments — a cover letter, a resume, and three reference letters — you send one clean, ordered file that opens the same way on every device and in every PDF reader.
Step by Step
How to Merge PDF on Android
1
Upload Your PDF Files
Drag two or more PDF files into the upload area, or click to browse and select them all at once. On Android, tap the upload area to open your file picker, or share directly from your gallery or Files app.
2
Check the File Order
Your files will be merged in the order they were added — the file list shows that order before you continue.
3
Click Merge PDF
Our server combines every page from every file into one new PDF, typically in a few seconds.
4
Download the Combined File
Save your merged PDF, or start over to merge a different set of files.
Get Better Results
Tips
- Rename Files Before Uploading — Since files merge in upload order, prefix filenames with 01-, 02-, 03- so they sort — and merge — in exactly the sequence you want.
- Compress Large Merges — If you are combining many image-heavy PDFs, run the result through Compress PDF afterward to bring the file size back down.
- Use the "Files" app or your gallery's share option to select the file, or upload it directly if it's already saved to your device.
- If a file is coming from Google Drive or another cloud app, download it locally to your device first, then upload it from there.
Avoid These
Common Mistakes
- Uploading a file that is already password-protected without unlocking it first — most operations require an unencrypted starting file.
- Assuming a converted or compressed file replaces the need for the original — keep your source file until you have confirmed the result looks right.
- Not checking the 50 MB upload size limit before starting, then wondering why a very large scan fails to upload.
- Searching an app store for a dedicated app when a mobile browser already does the job without extra storage or permissions.
Frequently Asked Questions
Yes. You can select and merge as many PDF files as you need in a single operation — there is no fixed limit on the number of files.
No. Merging copies each page exactly as it exists in the source file rather than re-rendering it, so text and images keep their original quality.
Not directly — an encrypted PDF needs to be unlocked with its password first using the Unlock PDF tool, then it can be merged normally.
No — it works directly in Chrome or any other Android browser, with nothing to install.
Download it to your device first, then upload it from your device's file picker — direct cloud-drive linking isn't supported yet.
