Privacy Policy
Last updated: March 2026
The Short Version
Your files never leave your device. Every Absolutool tool runs 100% in your browser using JavaScript. We have no server that receives, stores, or processes your files.
How File Processing Works
When you use any Absolutool tool — whether you're merging PDFs, compressing images, or formatting JSON — all processing happens locally in your web browser. The files you select are read by JavaScript running on your device. The output is generated on your device. At no point does any file data travel over the internet to our servers or any third-party service.
You can verify this yourself: open your browser's Developer Tools (F12), go to the Network tab, and use any tool. You'll see zero file upload requests.
Text & Data Tools
Tools like the JSON formatter, Base64 encoder, word counter, and all text utilities process your input entirely in JavaScript. No text you type or paste is ever transmitted anywhere. The same applies to generators (passwords, UUIDs, Lorem Ipsum) — all values are generated locally using your browser's built-in APIs.
Open-Source Libraries We Use
Absolutool loads a small number of open-source JavaScript libraries from CDN (cdn.jsdelivr.net) to power specific tools. These libraries run in your browser — they do not send data externally. The libraries include:
| Library | Purpose | Used By |
|---|---|---|
| pdf-lib | PDF creation & manipulation | PDF Merge, Split, Compress, Rotate, Watermark, Page Editor, Page Numbers |
| pdf.js | PDF rendering & text extraction | PDF to Image, PDF to Text |
| JSZip | ZIP file creation | PDF Split, PDF to Image, batch converters |
| heic2any | HEIC image decoding | HEIC to JPG converter |
| mammoth | DOCX to HTML conversion | Word to PDF |
| html2pdf.js | HTML to PDF rendering | Word to PDF |
Local Storage
Absolutool uses your browser's localStorage to save your preferences (theme, language, recently used tools). This data stays on your device and is never transmitted. You can clear it at any time through your browser settings.
Analytics & Advertising
We may use privacy-respecting analytics to understand which tools are popular and how visitors find our site. We may display ads through Google AdSense. These services operate independently and are governed by their own privacy policies. Importantly, neither analytics nor advertising services have access to any files you process with our tools.
Cookies
Absolutool itself does not set cookies. Third-party services (analytics, advertising) may set their own cookies. You can manage cookie preferences in your browser settings.

Verify It Yourself
We encourage you to verify our privacy claims. Here's how:
- Open any Absolutool tool in your browser.
- Press F12 to open Developer Tools.
- Click the Network tab and clear any existing entries.
- Use the tool with a test file.
- Look at the Network tab — you'll see zero outgoing requests containing your file data.
You can also disconnect from the internet after loading the page and use any tool. It will work perfectly because nothing needs a server.
