Merge PDF files without sending them anywhere
Most online tools that merge PDF files upload them to a server first. iLovePDF, Smallpdf, PDF24, Adobe Acrobat online and Sejda all process your files on their own servers, then delete them after a while. That is fine for a menu, less fine for a contract, a payslip or a medical letter.
This PDF merger works differently. Your browser reads the files, joins the pages and builds the new PDF on your own device. The documents are never sent to our servers, so there is nothing to delete afterwards.
There is no account, no watermark on the result and no daily task limit. You can combine PDF files as often as you like.
How to combine PDF files into one
- Add your PDFs: drop them on the tool or pick them from your device. You can add more at any time.
- Check the page count shown for each file, so you know you have the right document.
- Drag the files into the order you want them in the final PDF.
- Remove any file you added by mistake.
- Press merge and download merged.pdf.
How it compares with other free PDF mergers
Free tiers elsewhere come with limits. Smallpdf allows 2 free tasks a day. Sejda allows 3 tasks an hour, 200 pages and 50 MB per file. Adobe Acrobat online allows one transaction per tool without an account. iLovePDF limits daily tasks and file size on the free plan. PDF24 is free with no artificial limits, but it still processes files on its servers.
Here the only real limit is your device. Merging runs on your computer or phone, so a very large set of files needs enough memory, and big files can be slow on an older phone.
- Private by default: files stay on your device.
- No sign-up and no watermark.
- No daily task limit and no file-size paywall.
- Works in Chrome, Edge, Firefox and Safari, on computers and phones.
What people use a PDF merger for
Joining PDFs is one of the most common document jobs, and it usually comes up at the worst moment: an application portal that accepts one file, or an accountant who wants everything in a single attachment.
Typical examples are a CV and cover letter sent as one document, a set of monthly bank statements for a mortgage or rental application, invoices and receipts for an expense claim, scanned pages that came out of the scanner as separate files, and chapters of a report written by different people.
Many of those files carry account numbers, addresses and signatures. Combining them on your own device means that sensitive set is never gathered together on someone else's server, even briefly.
Tips for a clean merged PDF
- Need only part of a file? Use Split PDF to extract the pages you want first, then merge the result.
- To reorder individual pages rather than whole files, open the merged file in Organize PDF.
- Rename merged.pdf after download so it is easy to find later.
- Turning images into a PDF instead? Use JPG to PDF, then merge that file with your other documents.
