Essential PDF Operations
1. Merge PDFs
Combine multiple PDF files into one document. Look for drag-and-drop reordering and support for at least 10+ files.
2. Split PDFs
Extract specific pages or page ranges. Visual page previews help you select the right pages.
3. Compress PDFs
Reduce PDF file size for email attachments. Basic compression (re-serialization) is safe and reliable.
4. Rotate Pages
Fix page orientation issues. Should support rotating individual pages or all pages at once.
5. Add Watermarks
Protect documents with text or image watermarks. Customizable position, opacity, and color.
6. Reorder Pages
Rearrange pages within a PDF. Visual drag-and-drop with page thumbnails.
7. Convert to/from Images
Convert PDF pages to JPG/PNG, or convert images to PDF.

Our Recommendation
For most users, a client-side tool suite that covers all essential operations is the best choice. You get privacy, speed, and convenience in one place without juggling multiple websites.
