How can we help?

Absolutely safe! All PDF processing happens entirely in your browser. Your files never leave your device - no uploads, no servers, no storage. We can't see your files because they never reach us.

SimplyPDF works on all modern browsers including Chrome, Firefox, Safari, and Edge. We recommend using the latest version for the best experience.

File size limits depend on your device's memory. Most modern devices can handle files up to 100MB. For very large files, consider using our compress tool first.

Yes! SimplyPDF is completely free with no hidden costs, no registration required, and no watermarks on your processed files.

In the merge tool, you can reorder files using the up/down arrows next to each file. The final PDF will follow the order shown in the list.

Yes! The split tool allows you to specify exact page ranges or extract individual pages. You can create multiple splits from a single PDF.

Our compression algorithm is designed to reduce file size while maintaining visual quality. Text remains crisp, and images are optimized intelligently.

We use industry-standard RC4 128-bit encryption, the same level used by professional PDF tools. Your password is processed locally and never transmitted.

First, try refreshing the page. If the issue persists, check that your PDF isn't corrupted by trying a different file. For encrypted PDFs, ensure you're using the correct password.

Processing time depends on file size and complexity. Large files or files with many images take longer. Close other browser tabs to free up memory for faster processing.

Check your browser's download settings and ensure pop-ups aren't blocked. Some browsers require permission to download files automatically.

Yes! SimplyPDF is fully responsive and works on mobile devices. However, for the best experience with large files, we recommend using a desktop or laptop.

Currently, most tools process one file at a time for optimal performance. The merge tool can combine multiple files, and we're working on batch processing features.

We're developing API access for enterprise users. Contact us if you're interested in programmatic PDF processing for your applications.

Once loaded, SimplyPDF can work offline for basic operations. However, we recommend staying connected for the best experience and latest features.
