Frequently asked questions
Is this PDF merger really free?
Yes, completely free with no limits. There are no hidden charges, no watermarks, and no sign-up required. We built this as a free utility for the community.
Do you store or upload my PDF files?
No. Your PDFs are processed entirely in your browser using JavaScript. The files never leave your device and are never sent to any server. Your data stays 100% private.
How many PDFs can I merge at once?
There is no hard limit on the number of files. You can merge as many PDFs as your browser can handle. Each file can be up to 50 MB.
Can I change the order of the PDFs?
Yes. After uploading your files, you can drag and drop them in the list to reorder them before merging. The final PDF will follow the order you set.
Will the merged PDF lose quality?
No. The tool copies pages directly from the source PDFs without re-encoding. Text, images, and formatting are preserved exactly as they are.
Does this work with password-protected PDFs?
No. Encrypted or password-protected PDFs cannot be merged with this tool. You need to remove the password first. For protected documents, try Parsli's AI-powered extraction.
What's the difference between this and Parsli?
This free tool merges PDF files. Parsli is a full AI-powered document extraction platform — it extracts structured data from documents, handles scanned PDFs, and connects to Google Sheets, Zapier, Make, and 5,000+ apps.
Can I merge PDFs on my phone?
Yes. This tool works on iPhone, iPad, and Android devices. Open the page in your mobile browser, upload your PDFs, and download the merged file directly.
What file size limit is there?
Each individual file can be up to 50 MB. Since everything runs in your browser, very large files or many files at once may take longer depending on your device.
Can I merge PDFs without installing software?
Yes. Just open this page, drag and drop your PDF files, reorder them if needed, and click merge. No software to install, no account to create.
How to Merge PDF Files for Free
Merging PDF files is a common task for anyone who works with documents. Whether you need to combine invoices, reports, or contracts, a reliable PDF merger saves time and keeps everything organized in a single file.
Most online PDF mergers require you to upload your files to their servers, create an account, or pay for a subscription. This tool is different — it runs entirely in your browser using JavaScript. Your PDFs are processed on your own device and never sent anywhere. It's completely free, with no limits.
When Do You Need AI-Powered Document Processing?
This free merger handles combining standard PDF files. But if you need to extract data from those documents — pull invoice amounts, read table data, or parse complex layouts — that's where AI-powered extraction comes in.
Parsli uses Google's Gemini AI to understand the full context of your documents. You define a schema — the exact fields you want extracted — and the AI pulls structured data from any document type. The extracted data flows automatically to Google Sheets, Zapier, Make, webhooks, or your own API.
