Frequently asked questions
Why use WebP instead of PNG?
WebP files are usually much smaller than PNG files that look the same, so web pages load faster. That helps visitors on phones and slow connections.
Is the transparent background kept?
Yes. WebP supports transparency, so logos and icons keep their see-through background.
Can every app open WebP?
Every current web browser shows WebP. Some older photo apps, printers and upload forms do not accept it, so keep your PNG if you need it for those.
Are my original PNGs changed?
No. FilesAll makes new WebP files and leaves your PNGs as they were.
Can I turn WebP back into PNG later?
Yes. Use WebP to PNG to convert a WebP file back.
Is FilesAll free?
Yes. You can use FilesAll free every day without signing up, and the tool shows how many free files you have left today. A free account gives you more each day, and Pro removes the daily limit.
Do I need to install anything?
No. FilesAll works in the web browser you already have, on Windows, Mac, Chromebook, iPhone and Android. There is nothing to install, and you do not need an account to start.
Are my files uploaded?
No. FilesAll does all the work inside your browser, on your own device. Your files are never sent to our servers or anyone else's, and they disappear when you close the tab.
