Merge PDF
Combine multiple PDF files into one document.
iLovePDF
All-in-one PDF toolkit.
Drag-and-drop interface, handles large files, maintains quality. Free tier allows multiple merges. Most popular PDF tool.
Why I picked this:
iLovePDF is my go-to for merging PDFs because the drag-and-drop interface makes it incredibly easy to combine multiple files. I can rearrange pages, handle large files, and the output maintains quality. I've merged everything from invoices to reports, and it always works perfectly. The free tier is generous enough for most of my needs.
PDF24
Free PDF tools suite.
Open-source PDF tools with offline option. Good privacy, no uploads required. Slightly less polished than iLovePDF but more privacy-focused.
