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. Many online "merge PDF" tools upload your files to their servers, which you may not want for contracts, IDs, or financial statements. DocFila merges on-device, free.

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 only some pages

To use only some pages of a file, open it first, delete the pages you do not need, save a copy, and merge that copy.

Merge then compress

The combined file can get large. Run the compress tool on the merged PDF afterwards.

Merge images and PDFs together

Turn photos into a PDF with the image to PDF tool, then merge that PDF with your other PDFs. Useful for attaching a photo of an ID to a contract, or bundling receipts onto an expense form.
