Frequently asked questions
Is the PDFWix pdf to pdf/a tool really free?
Yes. PDF to PDF/A is 100% free, with no hidden charges, no signup, and no watermarks added to the output.
Are my files safe when I use PDF to PDF/A?
Most processing happens directly in your browser, so your file never reaches our server. When server processing is required, files travel over HTTPS and are processed in memory only — never written to disk.
Will PDF to PDF/A reduce the quality of my document?
No. PDFWix preserves the original quality of your file, including text, images, fonts, and formatting.
