Merge PDF
Combine several PDFs into one file in the order you choose.
Upload two or more PDF files, arrange them in the desired order, and download a single merged document. The files are joined in the sequence shown in the list.
How it works
- Add between 2 and 10 PDF files
- Reorder the list before merging so pages appear in the right sequence
- Each uploaded file can be up to 20 MB
Limits
- Encrypted PDFs must be unlocked first
- Digital signatures become invalid after the document is rebuilt
- Bookmarks and interactive forms may not carry over unchanged
Files are stored temporarily for processing, then removed.
Security and privacy
Encryption at rest
Files are encrypted during storage with AES-256-GCM using a unique key per file
Auto-deletion
Uploaded and processed files are removed after the session ends
Temporary sessions
Processing sessions expire automatically and are not kept as a permanent archive
Protected download links
Downloads require a short-lived access token — not a public permanent URL

Yes. Files are transferred over a secure connection, encrypted while stored on the server, and automatically deleted. Flimpa does not store documents permanently and does not use them to train models.
