How to merge PDF files into one document
Combine invoices, scans, or forms in your browser — pages stay as they are.
Application packs and signed forms often arrive as many PDFs. A merger concatenates them into one file you can send — without reprinting or screenshotting pages.
Order the files, then download
On Filvo, drop up to 25 unlocked PDFs (40 MB each, 120 MB total), drag them into order, and download. Pages are copied, not recompressed, so quality does not drop. Locked files need to be unlocked first.
When merge is the wrong first step
If you only need some pages from a large pack, split first, then merge what you kept. If the result is still huge, compress it. Dedicated pages exist for combining files, two PDFs, or invoice stacks. Everything stays in the browser.
Steps
- Drop the PDFs. Up to 25 unlocked files, 40 MB each, 120 MB total.
- Drag into order. The stack you see is the page order you get.
- Download one file. Pages are copied as-is — no extra compression.
