About FreeAIPDF

Who runs it

FreeAIPDF is a one-person project. I'm Durgesh Vijay: I run it on my own, test the tools and answer the email. The site is paid for by the ads described below.

You can reach me at durgeshghiya@gmail.com. The contact page says what to include when you report a problem.

Why it exists

Most online PDF services upload your file to their server to process it. For a bank statement, an ID scan or a signed contract, many people would rather not. Browsers can now do most PDF work themselves, so FreeAIPDF does the work on your device: the file is read into the page, processed there, and handed back as a download.

How the tools work

• Page editing: merging, splitting, reordering, rotating, cropping, page numbers and watermarks use two open-source libraries, pdf-lib and pdf.js, running inside the page.
• Text recognition (OCR): scanned pages are read by the open-source Tesseract engine, compiled to WebAssembly (tesseract.js). The engine and its English model are downloaded from this site the first time you use OCR, then run on your device.
• Tables, Markdown and summaries: table extraction, PDF to Markdown and the summarizer are this site's own code, which works from where the text sits on the page. The summarizer (TextRank) returns the document's own sentences. No AI model or outside service is involved.
• Scanning: Scan to PDF finds the edges of the page in the camera picture, straightens it and evens out the lighting, on your device.

What the tools cannot do

• There is no Word or PowerPoint conversion, no Excel to PDF, no repair and no translation, because those need a server. PDF to Excel does work here: it reads the tables from the text inside the PDF.
• Scanned PDFs need OCR before the text tools can read them, and OCR reads English only. The summarizer is also built for English text.
• Watermark and Page numbers use the standard PDF fonts, which cannot write non-Latin scripts such as Arabic, Chinese, Cyrillic or Devanagari.
• Files can be up to 100 MB each, 20 at a time. Big files can be slow on a phone.
• Sign PDF places a picture of your signature on the page. It is not a certificate-based digital signature.
• Protect PDF's password is real AES-256 encryption, but its permissions (printing, copying, editing) are a request to the reader software, not a lock.

How the tools are tested

I test each tool with real sample files in desktop and mobile browsers before it goes live, and fix problems readers report.

How the guides are written

Guides are drafted with AI assistance, then checked against how the tools actually behave. Each guide shows the date it was last updated. If a guide does not match what a tool does, please tell me.

How the site is paid for

The privacy policy explains what Google's ad code does and what the web host records.

Checking the privacy claims yourself

The site's Content Security Policy tells your browser that the page may load code from, and connect to, only this site and the Google domains its ads use. You can check that no file leaves your device: open your browser's developer tools, choose Network, and run a tool. You will see the page's own files and Google's ad requests, but no request that carries your document.
