The Problem With "Free" PDF Editors§
Search for "free PDF editor online" and you'll find tools that promise the world but deliver frustration. They add watermarks to your output. They require email signup before you can download. They limit you to 2 documents per day. And most of them upload your PDFs to their servers — which is especially problematic for contracts, legal documents, and confidential reports.
The reality is that most "free" PDF editors are either trial versions of paid software or ad-supported services that monetize your data.
A Complete PDF Toolkit — No Strings Attached§
NexaTools offers a full suite of PDF tools that run entirely in your browser. No uploads, no watermarks, no signups, no limits. Here's what's included:
- Merge PDFs — Combine multiple PDF files into one document
- Split PDF — Extract specific pages from a PDF
- Rotate PDF — Fix page orientation instantly
- Delete Pages — Remove unwanted pages
- Add Page Numbers — Number every page automatically
- Add Watermark — Overlay text or image watermarks
- Redact PDF — Permanently black out sensitive text
- PDF to Images — Convert PDF pages to PNG/JPG
- Images to PDF — Convert images into a PDF document
How It Works — Client-Side PDF Processing§
NexaTools uses two battle-tested open-source JavaScript libraries:
- pdf-lib — Handles document manipulation (merge, split, rotate, annotate, watermark)
- PDF.js (by Mozilla) — Renders PDF pages for visual operations like redaction
Both libraries run entirely in your browser. When you load a PDF, it's parsed and manipulated in memory. The modified PDF is generated locally and downloaded directly from your browser. No data ever leaves your device.
Use Cases§
- Legal professionals redacting sensitive information from contracts
- Students merging research papers and adding page numbers
- Business users combining reports and presentations
- Anyone who needs quick PDF edits without installing software

Frequently Asked Questions§
Is there a file size limit?§
No. Your PDF can be as large as your browser can handle. For very large files (100+ pages), modern browsers handle them without issue.
Do you store my PDFs?§
No. Your PDFs are processed entirely in your browser's memory. No files are uploaded to any server. Once you close the tab, the data is gone.
Can I redact text permanently?§
Yes. The PDF Redactor permanently removes text from the PDF content stream — it's not just a black box overlay. The underlying text data is stripped.
