Merge PDF
Combine multiple PDF files into one document in your browser. Drag files, arrange order, and download a single merged PDF without uploading to any server.
Merging PDFs is one of the most common document tasks. People combine invoices, reports, scanned chapters, and class handouts—and many prefer not to upload sensitive files to a third-party converter. PareKit merges PDFs entirely in your browser using pdf-lib, so nothing leaves your device during processing. Select several files, put them in the sequence you need, and save one output document. Practical limits—about fifty megabytes total and two hundred combined pages—keep tabs responsive on typical devices.
PDF merge joins several documents into one file in the order you choose. Upload each PDF and review the list so chapter one really comes before chapter two. Password-protected or heavily corrupted files may trigger an error—unlock or re-export them on your computer first. This tool accepts PDF input only; for photos or screenshots, use Image to PDF on the same hub and then merge. Healthy sources keep text and vectors intact in the output. Large scans use more memory, so staying within the published caps reduces the chance of a slow or stuck tab. Typical uses include bundling contracts, joining lecture notes, combining receipts for expenses, and turning many exports into one attachment. We do not store your documents or add watermarks. After download, keep a backup and confirm page order before you send the file onward. Bookmark the page if you merge often—after assets load, many browsers let you work offline.
How to merge PDF files
- Upload your PDFs — Select or drag multiple PDF files into the tool. Each file appears in the merge list.
- Arrange the order — Reorder items so the first file in the list becomes the first pages in the merged PDF.
- Merge and download — Click merge, then save the single combined PDF to your device. Verify page order before sharing.
FAQ
Is merge PDF free?
Yes. There is no payment, no account required, and no watermark added to your merged file.
Are my PDFs uploaded to a server?
No. Merging runs locally in your browser with pdf-lib. Your files are not sent to our servers.
Can I change the order of files before merging?
Yes. Reorder the list so the final PDF follows the sequence you want from first page to last.
What size and page limits apply?
Each job supports roughly fifty megabytes total and up to two hundred pages combined. Split very large jobs if you hit a limit.
Why did merging fail?
Common causes include password-protected PDFs, corrupted downloads, or exceeding limits. Unlock the file or re-export it, then try again.
