PDFs are everywhere — contracts, reports, ebooks, invoices. But editing them, merging files, or converting between formats used to require expensive software. In 2026, you can do all of this for free in your browser. Here are the seven best tools.
1. FZ-Tools PDF Editor
FZ-Tools's PDF Editor lets you annotate, highlight, add text, and sign PDFs directly in your browser. No upload to external servers — everything runs locally.
Best for: Signing documents, adding annotations, filling forms.
Cost: Free, no signup.
2. FZ-Tools PDF Merge
Need to combine multiple PDFs into one? PDF Merge lets you drag-and-drop files, reorder them with drag handles, and download the merged result instantly. Supports unlimited file count.
Best for: Combining reports, combining chapters, merging scanned documents.
Cost: Free, unlimited.
3. FZ-Tools PDF Split
PDF Split offers three modes: split all pages into individual files, pick specific pages, or define a page range. Great for extracting specific sections from large PDFs.
Best for: Extracting chapters, separating invoices, isolating pages.
Cost: Free.
4. FZ-Tools PDF Compress
Large PDFs can be slow to email and upload. PDF Compress reduces file size using object stream optimization. Shows before/after file size comparison so you can see exactly how much space you saved.

5. FZ-Tools PDF to JPG

Best for: Creating preview images, sharing PDF content as images, extracting diagrams.
Cost: Free.
6. FZ-Tools JPG to PDF
Got a stack of scanned images or photos? JPG to PDF converts and combines them into a single PDF. Supports drag-to-reorder, three fit modes (letterbox, fill, actual size), and A4 page size.

Cost: Free.
7. iLovePDF (External)
