Sending one file is easier than sending five. Merging also keeps pages in a clear order for the reader. Here is how to combine PDFs, and photos too, in a few clicks.
Merge in four steps
- Open your first file in the WriteDroid PDF Editor.
- In the Pages panel press Add and choose more PDFs or images (JPG, PNG, WebP). They are added after the current pages.
- Drag the thumbnails into the right order.
- Press Save PDF.
Handy page tools while you merge
- Delete pages you do not need.
- Rotate pages that came in sideways.
- Blank page to add a separator.
- Duplicate a page you need twice.
Photos into PDF
Drop a few phone photos into the editor and they become pages. Rotate and order them, then save. For crisp document photos, clean them up first with the image scanner.
Keep the result small
Merging scans can make a big file. Open Save options and pick a smaller size before saving. See how to reduce PDF file size.
Merge limits
Everything runs on your device, so very large files depend on your memory. If a phone struggles with a huge file, merge on a computer or in smaller batches.
After merging
Add page numbers so the combined file reads as one document. To go the other way, read how to split a PDF into pages.
Common questions
Is there a limit on the number of files? No fixed limit. Your device memory is the limit.
Do links and forms survive? Pages are copied with their content, and links are kept where possible.
Can I merge a locked PDF? Open it with its password first. It is then added like any other file.
