Frequently Asked Questions
Is this tool completely free?
Yes! File Gulp provides completely free file conversion tools with no hidden fees, no watermarks, and no registration required.
Are my files safe?
Absolutely. Unlike other converters, File Gulp uses modern WebAssembly technology to convert files directly on your device. Your files never leave your computer, ensuring maximum privacy.
Does it work on mobile devices?

Will the quality be affected?
No, we use high-quality algorithms to ensure your output files maintain the best possible quality during conversion.
Is there a file size limit?

Choosing Your Watermark Type
