    FAQ

    Frequently asked questions

    Is PDFZoa free?
    Yes. Every tool is free to use and adds no watermark.
    Are my files uploaded to a server?
    No. Your files are processed inside your own browser and never leave your device. That's why it's fast and completely private.
    What is the maximum file size?
    Up to 100 MB per file. Very large files depend on your device's memory.
    Do I need an account?
    No. There are no accounts and no sign-up — every tool is free to use right away.
    Do I need to install anything?
    No installation is required. Browser support and file limits depend on the selected tool; some processing features require a recent browser.
    Will the formatting be kept?
    Text and simple tables are kept. Complex layouts, special fonts and images may not come through exactly, so check the result. Scanned PDFs contain only pictures of text — run OCR PDF first.
    Can I convert many files at once?
    Yes. Select or drop several files; multiple results can be downloaded as one ZIP or one by one.
