How to Merge PDF On Windows
Windows doesn't include a native PDF merging tool—Microsoft Print to PDF can create PDFs but can't combine them. Most Windows users resort to paid software like Adobe Acrobat or random free tools bundled with adware. SublimePDF's web-based merge tool works in any Windows browser (Edge, Chrome, Firefox) with no installation, no ads, and no file size surprises. For power users, PowerShell and command-line options also exist.
Follow the step-by-step instructions below, then use the free tool directly — no registration or download required.
Open Tool →How to Merge PDF On Windows — Step by Step
Open SublimePDF in your browser
Navigate to SublimePDF's Merge PDF tool in Microsoft Edge, Chrome, or Firefox on your Windows PC. No installation or account creation is required—the tool runs entirely in your browser.
Upload your PDF files
Click 'Upload' or drag files from File Explorer onto the upload area. You can select multiple files at once by holding Ctrl while clicking in the file picker. Files are uploaded and queued for merging.
Arrange the merge order
Drag and drop file cards to set the order. The first file's pages appear first in the merged output. Expand any file to rearrange or exclude individual pages.
Configure merge settings
Choose whether to generate a table of contents from filenames, preserve individual bookmarks from each file, or optimize the output for a smaller file size. These options aren't available in basic Windows workarounds.
Merge and save to your PC
Click 'Merge' to combine all files. Once processing completes, click 'Download' and save the file to your preferred location. Edge and Chrome save to your Downloads folder by default.
Pro Tips
- 💡 Drag files directly from File Explorer into the browser window—this is faster than using the upload button, especially when your files are spread across different folders.
- 💡 If you frequently merge PDFs on Windows, bookmark SublimePDF's merge page to your taskbar for one-click access.
- 💡 For command-line users, PowerShell can call PDFtk or Ghostscript for batch merging, but these require separate installation. SublimePDF requires nothing beyond your browser.
- 💡 Windows 11 users can install SublimePDF as a Progressive Web App (PWA) from Edge for an app-like experience with offline launch capability.
Privacy & Security
All processing happens directly in your browser. Your files are never uploaded to any server — they remain on your device throughout the entire process. SublimePDF uses WebAssembly technology for fast, secure, client-side processing.
Works Everywhere
This tool works on any modern browser — Chrome, Firefox, Safari, or Edge — on desktop, tablet, or mobile. No software to install. PDF is an open ISO standard supported by all major platforms.

How to Merge PDF On Mac
macOS includes built-in PDF merging through Preview, making it one of the few operating systems where you can combine PDFs without extra software. However, Preview's approach has limitations—it modifies the original file, offers no compression, and doesn't support batch operations. For quick two-file merges, Preview is convenient. For anything more complex, SublimePDF's online tool provides reordering, selective page merging, and file size optimization.

Combining multiple PDFs on your iPhone is essential when you need to submit a single document from several files — like merging scanned receipts, consolidating travel documents, or assembling application materials on the go.
