Frequently Asked Questions
How is FileFlex 100% private?
FileFlex runs entirely using modern Web APIs inside your browser thread (HTML5 Canvas and File Reader APIs). Your files are converted using your own computer's processor and RAM. Nothing is ever uploaded to a cloud server or external database.
Is there a file size limit or daily conversion quota?
No! Because we don't have server hosting bandwidth costs for your files, you can convert as many images as your browser can handle without paying fees or creating an account.
Why use WebP instead of JPEG or PNG?
WebP is a modern image format developed by Google that provides superior lossless and lossy compression. WebP images are typically 25–34% smaller than equivalent JPEGs while retaining high visual quality.
