Who uses this
Pretty much anyone who deals with PDFs. Here are a few we hear from the most.
Students
Combining scanned assignment pages, lecture notes, and research papers into one file before submitting. Professors don't want five separate uploads.
Lawyers & paralegals
Merging case documents, exhibits, and filings into a single bundle. Courts often require everything in one PDF, and this beats paying for desktop software.
Accountants
Compiling monthly reports, receipts, and financial statements into one package for clients. Way cleaner than sending a dozen attachments.
Freelancers
Putting together invoices, contracts, and project deliverables into a single file. Clients appreciate not having to dig through multiple documents.
Teachers
Creating exam packets, combining worksheets, or assembling course materials from different sources into one printable PDF.

Why not just use Adobe?
Look, Adobe Acrobat is great software. But it costs $20+ a month, requires a download, and honestly it's overkill if all you need to do is stick a few PDFs together. That's like renting a moving truck to carry a backpack.
This tool does one thing and does it well. You open the page, drop your files, click merge, and you're done. No account to create. No credit card. No "your free trial has expired" popup three weeks from now. It works on your phone, your laptop, your work computer — anywhere you've got a browser.
And because everything runs online, there's nothing to install or update. You don't need admin permissions on your machine. You don't need to worry about compatibility. It just works.
Frequently Asked Questions
Do I have to pay for this?
Nope. It is free. No account needed either.
Is there a limit on how many PDFs I can combine?
There is no hard limit. People have merged 50+ files at once without issues.
What if I want the files in a specific order?
You can drag them around after uploading. The final PDF follows whatever order you set.
Will my images or formatting get messed up?
Nothing changes inside the PDFs. They get stitched together as-is.
Do I have to download anything?
No. The whole thing runs in your browser. Chrome, Safari, Firefox, whatever you use.
What happens to my files after?
They get deleted from our servers within an hour. We don't keep copies.
What if one of my PDFs is password-protected?
You'll need to unlock it first. We've got a free unlock tool right on this site — use that, then come back and merge.
Can I merge PDFs from my phone?
Absolutely. The tool works in any mobile browser. No app to install.
Is there a page limit?
Not really. We've seen people merge documents with hundreds of pages total. If the combined file is under 100MB, you're good.
What about PDFs with different page sizes?
Each page keeps its original size. So if one PDF is letter-sized and another is A4, both stay exactly as they are in the merged file.
Can I merge image-heavy PDFs?
Yes, and they won't lose quality. The images stay at their original resolution. Just keep in mind that lots of images means a bigger file size.
How long are files stored?
One hour max. After that, they're automatically wiped from our servers.
Do you support drag-and-drop reordering?
You bet. After uploading, just drag the files into whatever order you want. The merged PDF follows that exact sequence.
What browsers work?
Chrome, Safari, Firefox, Edge — basically anything modern. If your browser is from this decade, you're fine.
