Frequently Asked Questions

Are these conversion tools completely free to use?
Yes, all our conversion tools are completely free to use with no hidden fees, subscriptions, or limitations. We believe in providing valuable tools without charging our users. There are no watermarks on your converted files, and you can use our tools as often as you need.
How does client-side processing protect my privacy?
Client-side processing means your files never leave your computer during conversion. Unlike server-based converters that upload your files to remote servers, our tools process everything locally within your browser. This eliminates the risk of unauthorized access, data breaches, or third-party monitoring of your sensitive documents.
What file formats do you support?
We currently support PNG to PDF, JPG to PDF, Word to PDF, Excel to PDF, and PowerPoint to PDF conversions. We're continuously working to add more file formats based on user demand. All conversions maintain the original quality and formatting of your documents.
Is there a limit on file size or number of files?
For optimal performance, we recommend files under 10MB each and processing up to 20 files at once. These limits ensure smooth operation across all devices and browsers. For larger files or batch processing needs, the conversion may take longer but will still work effectively.
Do the converted PDFs work on all devices?
Absolutely! Our conversion tools create standard PDF files that are compatible with all PDF readers and devices. Whether you're using Windows, Mac, iOS, Android, or Linux, your converted PDFs will display correctly and maintain their formatting across all platforms.
