Why Merge PDFs?
Students often need to combine files:
- Lecture notes from different weeks into one document
- Assignment pages scanned separately
- Research papers for a literature review
- Project reports with appendices
How to Merge PDFs with StudyFlow
- Go to our Merge PDF tool
- Drag and drop your PDF files (or click to browse)
- Use the arrow buttons to reorder files
- Click Merge & Download
That's it. Your merged PDF downloads instantly.
Why Browser-Based is Better
Most online PDF tools upload your files to their servers. This means:
- Your documents travel over the internet
- They sit on someone else's server
- You're trusting a company with your academic work
Our tool processes everything in your browser. Your files never leave your device.
Tips for Better Results
- Name your files with numbers (01-intro.pdf, 02-methods.pdf) for easy ordering
- Check page sizes — mixing A4 and Letter can look odd
- After merging, use our Compress PDF tool if the file is too large for your LMS
- Need to remove pages? Use Split PDF first
File Size Limits
There's no hard limit since processing happens on your device. However:
- Files over 50 MB may be slow on older devices
- If your browser runs out of memory, try merging in batches
