Yes! Since processing happens entirely in your browser with no server uploads, you can safely use our tools for confidential, sensitive, or private documents without any security concerns.

Your files exist only in your browser's memory during processing. After you download the result or close the page, all data is automatically cleared from memory. Nothing is stored anywhere.

We don't impose artificial file size limits. However, very large files (over 100MB) may process slowly depending on your device's memory and processing power. Most documents under 50MB process quickly.

There are no limits on the number of files you can process. For combining PDFs, you can merge as many files as needed. Processing happens sequentially, so more files will take proportionally longer.

Password-protected PDFs need to be unlocked before processing. You'll need to remove the password using the original password first, then use our tools on the unlocked file.

No daily limits! Use our tools as much as you need, whenever you need. Process unlimited files without any restrictions or quotas.

Processing speed depends on your device's CPU and available memory. Large files or older devices may process more slowly. Closing other browser tabs and applications can improve performance.

You need an internet connection to load our website and tools initially. Once loaded, the PDF processing libraries are cached in your browser and can work offline until you refresh the page.

No quality loss! Our tools maintain 100% of the original PDF quality. All text, images, fonts, and formatting remain identical to the source document.

We use PDF-lib, a modern JavaScript library that processes PDFs entirely in your browser. This client-side processing ensures your privacy while delivering professional-quality results.

Try refreshing the page and uploading your file again. Ensure your browser is updated to the latest version. If problems persist, try a different browser or clear your browser cache.

Ensure the file is a valid PDF and not corrupted. Try opening it in a PDF reader first. Very large files may take time to load. Check that your browser allows file uploads and JavaScript is enabled.

Check your browser's download settings and ensure pop-ups aren't blocked. Some browsers require permission to download files. Look for download prompts in your browser's notification area.
