PDF Merger Guide

Why Merge PDF Files?

Combining multiple PDF files into one keeps related documents together, makes sharing easier, and reduces the number of attachments you send. Whether you're consolidating a multi-chapter report, bundling a CV with a cover letter, or combining scanned pages into a single archive, a PDF merger saves time and keeps things organised.

  • One file, zero confusion: Combine contracts, invoices, or reports so recipients get everything in a single attachment.
  • Combine PDFs and images: Embed JPG or PNG scans directly alongside existing PDF pages - no pre-conversion needed.
  • Custom page order: Drag files up or down to set the exact page sequence before merging.
  • Instant download: Get the merged PDF in seconds - no waiting, no email delivery.
  • 100% private: All processing happens in your browser. Your files are never uploaded to a server.
  • Works everywhere: Mac, Windows, Linux, iPhone, Android - any modern browser, no software needed.

How to Merge PDF Files Online

Merging PDFs online takes under a minute. The tool runs entirely in your browser using pdf-lib, so there are no uploads and no waiting for a server response - even large multi-file merges complete in a few seconds.

  1. Click Select Files or drag your PDFs, JPGs, or PNGs into the upload area.
  2. Use the arrow buttons to set the order your files should appear in the merged PDF.
  3. Click Merge PDFs, then Download Merged PDF to save the file.

Step 1: Upload Your Files

Drag and drop your PDF, JPG, or PNG files onto the upload area, or click "Select Files" to browse. You can add as many files as you need in one go. Each file can be up to 50 MB.

Step 2: Set the Page Order

Use the up and down arrows next to each file to arrange them in the order you want. The top file becomes the first pages of the merged PDF, and so on. You can add more files at any time before merging.

Step 3: Merge and Download

Click "Merge PDFs" to combine all files. The process completes in seconds. Once done, click "Download Merged PDF" to save the combined file to your device - no watermarks, no restrictions.

Key Features of This PDF Merger

Combine PDFs and Images Together

Most online PDF mergers only accept PDF files. This tool also accepts JPG and PNG images, converting each image into a full-page PDF page automatically. This makes it ideal for combining scanned photos, screenshots, or design exports with existing PDF documents - without any extra conversion steps.

Reorder Files Before Merging

Getting the page order right matters. Use the arrow buttons to move any file up or down in the list. The final merged PDF respects the order shown, so you always get exactly the sequence you intended.

Privacy First - No Server Uploads

Your PDF files may contain sensitive contracts, financial records, or personal information. Unlike cloud-based mergers, this tool processes everything locally using the pdf-lib library in your browser. Files never leave your device.

Completely Free, No Account Required

There are no usage limits, no watermarks added to the output, and no registration required. Merge as many PDFs as you need, as often as you need - entirely free.

Frequently Asked Questions

How do I merge 2 PDFs into one?

Upload both PDF files using the tool above, check the order in the list, and click "Merge PDFs." The combined file is ready to download in a few seconds. No account, no software, and no cost.

Can I combine a PDF and a JPG image?

Yes. This tool accepts PDF, JPG, and PNG files in any combination. Each image is converted to a full PDF page automatically, then merged in the correct order with your other PDFs. Just upload both files, arrange the order, and merge.

Is merging PDFs online safe?

With QuickTooly, yes - because your files are processed entirely in your browser using client-side JavaScript. They are never sent to any server. This makes it safe to merge confidential contracts, financial documents, and personal files.

Can I merge PDF files on Mac, Windows, or Linux?

Yes. The merger works in any modern browser on any operating system - Mac, Windows, Linux, as well as mobile devices running iOS or Android. No desktop software or browser extensions are needed.

Is there a file size limit?

Each individual file can be up to 50 MB. There is no hard limit on the total number of files you can merge at once, though very large merges may take a few extra seconds depending on your device.

Does merging PDFs reduce quality?

No. This tool copies pages byte-for-byte using pdf-lib, so text, fonts, vector graphics, and layout are preserved exactly as they appear in the originals. JPG and PNG images you add are embedded at their original resolution - there is no re-compression or quality loss.
