🔒 Privacy First: All PDF merging happens 100% locally on your device. Your documents never leave your computer or phone. No file upload, complete privacy.

🚀 Step 1: Select & Upload Your PDF Files

Two ways to add files:

  • Click Method: Tap the dashed upload area to open file picker. Select multiple files (hold Ctrl/Cmd).
  • Drag & Drop: Drag PDF files directly onto the upload area from your file manager.
  • Only PDF (.pdf) files under 50MB each are accepted.
  • Files merge in the order shown — first file becomes first pages.

📋 Step 2: Arrange Files in Correct Order

Use these controls to organize:

  • ▲ Up: Move file one position up (earlier in merge order).
  • ▼ Down: Move file one position down (later in merge order).
  • ✕ Remove: Delete a file from the list if added by mistake.
  • Put title page first, supporting documents after.

🔗 Step 3: Merge Your PDF Files

When files are arranged:

  • Click "Merge PDFs" to start combining.
  • Progress bar shows status — takes seconds to a minute depending on file sizes.
  • All pages, text, images, and formatting are preserved.
  • Requires minimum 2 PDF files to merge.

📥 Step 4: Name & Download Your Merged PDF

After merging:

  • Type a custom file name in the input field.
  • .pdf extension is automatically added if forgotten.
  • Click "Download Merged PDF" or press Enter key.
  • Original files remain unchanged on your device.

🔄 Step 5: Merge More or Start Fresh

Click "Clear All" to remove all files and start over. Merge different combinations unlimited times — completely free.

💡 Best Practices: Merge up to 10-15 files at once for best performance. Total size under 100MB recommended. Review order carefully before merging.
⚠️ Troubleshooting: Password-protected PDFs cannot be merged. Corrupted files may cause errors. Use modern browser (Chrome, Firefox, Safari, Edge).
