FAQ
Frequently Asked Questions
Is PDFDroid completely free?
Yes. All 38+ PDF tools on PDFDroid are free — forever. No subscription, no watermark, no account required.
Are my PDF files private and secure?
Yes. All processing happens entirely in your browser using JavaScript. Your files are never uploaded to any server — they stay 100% on your device.
Does PDFDroid work on mobile phones?
Absolutely. PDFDroid is fully responsive and works perfectly on all devices — phones, tablets, laptops, and desktops.
What is the maximum PDF file size I can process?
Since processing is done in your browser, it depends on your device's RAM. Most modern devices handle files up to 200MB easily. For very large files, we recommend using a device with more RAM.
Can I use PDFDroid offline?
After the initial page load, most tools work offline since no server requests are made during file processing.
Is PDFDroid better than iLovePDF or Smallpdf?
Unlike iLovePDF and Smallpdf which upload your files to their servers, PDFDroid processes everything locally in your browser — making it significantly more private and secure, with no file size restrictions or daily limits.
