How It Works

All processing is done locally in your browser using powerful open-source libraries like pdf-lib, pdf.js, html2pdf, mammoth, and Tesseract OCR. This ensures fast, reliable, and secure processing — even for large files — without any server dependency.

For example, when you use our pdf to excel tool, we extract text from each page and structure it into a CSV format that can be opened in Excel. Similarly, excel to pdf converts your spreadsheet into a beautifully formatted PDF using xlsx and html2pdf.

Need to convert images to PDF? Our jpg to pdf and png to pdf tools embed your images into a single, high-quality PDF. For the reverse, pdf to jpg and pdf to png extract each page as a separate image and zip them for easy download.

Our organize tool lets you merge up to 100 PDFs at once — perfect for combining contracts, reports, or academic papers. And with page numbers and crop tools, you can refine your document to perfection.

Privacy & Security

Your privacy is our top priority. Unlike other online tools that upload your files to their servers, pdfaid never sends your files anywhere. Everything happens in your browser. Once you close the tab, your data is gone. This makes pdfaid one of the most secure options for handling sensitive documents like contracts, medical records, or financial statements.

Offline & Mobile Friendly

Our tools are optimized for all devices — desktop, tablet, and mobile. And thanks to service workers, many features work even offline after the first load. This makes pdfaid perfect for use on the go, in classrooms, or during travel.

Whether you're a student preparing for exams, a professional managing contracts, or a creative designer converting files, pdfaid gives you the freedom to work efficiently and securely.
