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?
Yes, our tool is fully responsive and works perfectly on smartphones and tablets, directly from your mobile browser.
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?
Very large files may be limited by your device memory/browser performance. For normal image sizes, conversion is fast and seamless.
Cryptographically secure randomness
This tool uses the browser's secure random number generator instead of predictable formulas. That matters because strong passwords must be genuinely random, not just visually complex.
Strong but easier to type
For accounts where typing is frequent, a memorable passphrase can be easier to use than a symbol-heavy password. This version uses a much larger local passphrase pool, so passphrase entropy reflects thousands of possible word tokens instead of a tiny demo list.
Why this generator is different
File Gulp focuses on privacy, clarity, and practical controls that help users create credentials they can actually use.
- 100% client-side: Passwords are generated in your browser and never uploaded to a server.
- Entropy estimate: See an approximate security score based on length and possible character combinations.
- Ambiguous character filter: Avoid confusing characters like
O,0,I, andl. - Bulk generation: Generate up to 50 unique passwords and export them as a local text file.
