Invoices, contracts, and scanned pages often arrive as separate PDFs. LightDocs lets you merge PDFs on Android entirely on the device. The app is free with AdMob ads and does not require an account.
When merging helps
- Bundle a quote and its annexes before email
- Join several scans into one dossier for WhatsApp
- Assemble pages exported from different apps into a single PDF
How to merge with LightDocs
- Install LightDocs from Google Play.
- Open the merge tool and select the PDFs to combine.
- Confirm order, then create the merged file on your phone.
- Open it in the built-in reader, compress it if needed, or share it.
Files stay on your phone during the merge. LightDocs does not upload them to process the job.
Pair with compress, split, and convert
After merging, you can compress the result for WhatsApp or email, split pages out again, or convert images to PDF first if some pages are still photos. Everything runs on-device.
Privacy and pricing
LightDocs is available on Android and iOS, free with discreet ads, and designed for everyday PDF tasks without forced cloud storage.
