Frequently Asked Questions
Find answers to common questions about PDFey tools
Is PDFey free to use?
Yes, all basic PDF tools on PDFey are completely free. You can merge, split, compress, and convert PDFs without any payment or registration required.
Are my PDF files secure?
Absolutely. All PDF processing happens entirely in your browser using JavaScript. Your files are never uploaded to any server. They stay on your device at all times, ensuring complete privacy and security.
How does browser-based processing work?
PDFey uses modern web technologies like pdf-lib and PDF.js to process your files directly in your browser. This means instant results with no upload or download wait times, and your sensitive documents never leave your computer.
What is the maximum file size supported?
Since processing happens in your browser, the limit depends on your device's memory. Most modern devices can handle PDFs up to 50-100MB without issues. For very large files, we recommend splitting them first.
How do I merge multiple PDFs?
Use our Merge PDF tool. Simply drag and drop or select multiple PDF files, arrange them in the desired order by dragging, and click "Merge PDFs". The combined file will be downloaded automatically.
Can I split a PDF into individual pages?
Yes! The Split PDF tool lets you extract specific pages or split a PDF into separate files. You can specify page ranges (e.g., 1-3, 5, 7-10) or split every page into a separate file.
How much can I compress a PDF?
Compression results vary depending on the PDF content. PDFs with images typically compress better than text-only documents. You can often achieve 30-70% size reduction while maintaining readable quality.
Can I convert PDF to images?
Yes! The PDF to JPG tool converts each page of your PDF into a high-quality JPG image. You can also convert the other way - JPG images to PDF documents.
How do I rotate pages in a PDF?
Use the Rotate PDF tool. Upload your PDF, select the pages you want to rotate, choose the rotation direction (90°, 180°, or 270°), and download the rotated PDF.
Can I delete specific pages from a PDF?
Yes! The Delete Pages tool lets you remove unwanted pages from your PDF. Preview all pages, click on the ones you want to remove, and download the updated document.
Can I reorder pages in a PDF?
Absolutely. The Reorder Pages tool displays all pages as thumbnails. Simply drag and drop them to rearrange the order, then download your reorganized PDF.
Can I protect a PDF with a password?
Yes! The Protect PDF tool lets you add password protection to your PDF files. Set an owner password to restrict printing, copying, or editing. The encryption is done entirely in your browser.
Can I unlock a password-protected PDF?
If you know the password, you can use our Unlock PDF tool to remove the password protection. Enter the current password, and download an unprotected version of your PDF.
Do the tools work offline?
Once the page is fully loaded, most tools will work offline since all processing happens in your browser. However, you need an internet connection to initially load the page.
What browsers are supported?
PDFey works in all modern browsers including Chrome, Firefox, Safari, and Edge. We recommend using the latest version of your browser for the best experience.
Can I use PDFey on mobile?
Yes! PDFey is fully responsive and works on smartphones and tablets. The interface adapts to your screen size for comfortable use on any device.
