Frequently asked questions
Are my files uploaded anywhere?
No. Filero runs entirely inside your browser using JavaScript. Your PNG files are never sent to a server, which makes it safe for personal photos, ID scans, or anything you'd rather not upload.
Does converting to WebP reduce quality?
WebP is a lossy format, so a small amount of detail is dropped to make the file smaller. At the "Best" quality preset the difference is usually invisible to the eye, while "Smaller" trades a bit of sharpness for a much lighter file.
Can I convert multiple PNG files at once?
Single-file conversion is free and unlimited. Batch conversion of many PNG files in one go is on the Filero Pro plan.
Is this PNG to WebP converter really free?
Yes. There are no signups, email walls, or watermarks on the converted image. Free users can convert files up to 25 MB; Pro removes the size limit and adds batch processing.
Does it work on iPhone, Android, and desktop?
Yes. Filero runs in any modern browser — Safari on iPhone, Chrome on Android, and every major desktop browser. There's nothing to install.
