How to Merge PDFs for Free (Without Uploading to Strangers)

By DocFila Team · April 28, 2026 · 4 min read

Combining several PDFs into one is the most common PDF task there is. Most online "merge PDF" tools upload your files to their servers — bad idea for contracts, IDs, or financial statements. DocFila merges on-device, free, in seconds.

Merge PDFs in DocFila

1. Open DocFila → PDF Tools → Merge.
2. Tap Add Files and select 2 or more PDFs (from device, cloud, or vault).
3. Drag the rows to set the order.
4. Tap Merge. The combined PDF is saved instantly.

Merge specific pages, not entire files

Tap a file in the merge list to expand it, then check only the pages you want. Useful for assembling a single PDF from scattered chapters of larger documents.

Merge then compress

The combined file can get large. Pipe it straight into the compress tool — DocFila offers "Merge + Compress" as one action.

Merge images and PDFs together

The merge tool accepts JPG, PNG, and HEIC images alongside PDFs. Useful for stapling a photo of an ID to a contract, or bundling receipts onto an expense form.
