Free PDF Merger: Combine PDF Files Online in Seconds
Tooly · 2026-08-02 · 5 min read
Scanned pages, multiple invoices, contract addendums — sooner or later you need several PDFs as one file. A free PDF merger combines them in seconds, and the best ones run entirely in your browser so your documents never leave your device.
Why merge PDFs?
- Submit one file — portals and email clients prefer a single attachment
- Organize documents — combine related papers into one clean PDF
- Speed — no desktop software, no installation, no account
- Privacy — client-side merging keeps sensitive docs local
Merge PDFs free with Tooly
The Tooly PDF Merger keeps it simple:
- Select multiple PDF files (up to 10 at once)
- Combine them into one PDF in the order you choose
- Runs in your browser — nothing is uploaded
- Free, no signup, no watermark
When you'll use it
- Combining scanned pages into one document
- Merging multiple invoices for a client (pair with InvoiceForge)
- Putting contract addendums into a single file
- Joining reports and appendices for submission
Best practices
- Check the page order before you merge — reorder files if needed
- Compress the result afterward with the PDF Compressor if it's large
- Keep originals — merging creates a new file, it doesn't delete the source
- For bank statements, BankToCSV converts PDFs to CSV instead
