Frequently Asked Questions

Are these PDF tools really free?

Yes. Every tool on PDFConverterFiles is free to use with no signup required. Because all processing happens in your browser, we have no server costs per file — so we can keep it free.

Are my files uploaded to a server?

No. All tools run entirely in your browser using JavaScript. Your documents never leave your device, which makes these tools ideal for sensitive contracts, medical records, and financial documents.

Is there a file size limit?

Each file can be up to 100 MB. Since processing happens on your device, the practical limit is your device's available memory — most PDFs work flawlessly.

Which browsers are supported?

Any modern browser: Chrome, Edge, Firefox, Safari, and Opera on desktop or mobile. For best performance with large files, use a desktop browser.

How strong is the PDF password protection?

The Protect PDF tool uses AES-128 encryption (PDF 1.6, V=4/R=4), the same standard used by desktop PDF software. Choose a long, unique password — no encryption can protect a weak password.

Can I use these tools on my phone?

Yes. The whole site is mobile-friendly — upload, process, and download PDFs or images right from your phone's browser.
