Frequently Asked Questions

Yes, absolutely. Your files are processed directly in your browser using modern web technologies. We never upload your files to our servers, so they never leave your device. All processing happens locally on your computer or mobile device.

Yes. Since we don't collect, store, or process personal data or files on our servers, we minimize data collection to the extent required for service operation. Our privacy-first approach aligns with GDPR principles.

For browser-based processing, the limit depends on your device's memory. Most modern browsers can handle files up to 100-500MB. For larger files, we recommend using desktop software.

Yes, if you know the password, our Unlock PDF tool can remove password restrictions from your document, allowing unrestricted access.

Our compression tool uses Ghostscript optimization to reduce file size while maintaining quality. For documents with images, some quality loss is possible, but we use settings that balance size reduction with readability.

Our PDF Editor allows you to add text annotations, highlights, shapes, and redactions. For extensive text editing of existing content, we recommend converting to Word format first, editing, then converting back to PDF.

First, ensure your file is a valid PDF and not corrupted. Try refreshing the page and uploading again. If the issue persists, try a different browser or device. For very large files, your browser may run out of memory.

If the automatic download doesn't start, check your browser's download settings. You can also right-click the download link and select 'Save link as'. Some browsers may block automatic downloads.

Processing speed depends on your device's processing power, file size, and complexity. Large files with many pages or high-resolution images will take longer. Ensure your browser has sufficient memory available.

Error messages usually indicate issues with the file format, file corruption, or browser limitations. Try uploading a different file to see if the issue is file-specific. If problems persist, contact us with details about the error.
