Drag & Drop Your PDF or Text Files Here
Combining multiple PDF files into a single document is one of the most common tasks anyone working with documents has to do. Whether you're putting together a final report from individual chapters, bundling invoices for a client, or stitching together signed contracts, FixMyPDF's Merge PDF tool gets the job done in seconds — no installation, no sign-up, and no watermarks.
Our merger preserves the original formatting, fonts, and quality of every file you upload. Page numbering, embedded images, hyperlinks, and bookmarks come through intact. Behind the scenes, we use industry-standard PDF processing libraries so your merged file is fully compatible with Adobe Acrobat, Apple Preview, browser viewers, and every modern PDF reader.
Best of all, the merge is performed by pdf-lib inside your own browser. Your documents are never uploaded to us, so contracts and financial records stay on your machine from start to finish.
For cleaner results, arrange the files before merging and use clear filenames such as 01-cover.pdf, 02-report.pdf, and 03-receipts.pdf. This is especially important for applications, contracts, invoices, and scanned packets where page order affects whether the final PDF makes sense.

Follow these simple steps to get the result you need in under a minute:
Most merges finish in under 5 seconds, even with many large files.
Merging happens in your browser with pdf-lib. Your PDFs are never uploaded to us.
Fonts, images, hyperlinks, and bookmarks are preserved.
No sign-up, no watermarks, no file count limit.
There is no fixed cap. Since merging runs in your browser, the practical limit is your device's memory rather than a quota we enforce.
No. Our merger combines the original page content as-is — no recompression, no rendering, no quality loss.
Yes. Bookmarks, internal hyperlinks, and table-of-contents entries from each source PDF are preserved in the merged file.
Password-protected PDFs must be unlocked first using our Unlock PDF tool. Locked files cannot be merged for security reasons.
Yes — completely free with no watermarks, sign-up, or file count limits beyond the size restrictions noted above.
Usually merge first, then compress the final document. That gives you one optimized file after the page order is finished.
Open the final file and confirm page order, orientation, signatures, blank pages, and file size before emailing or uploading it.
