Frequently asked questions
Why convert JPG to WebP?
WebP usually produces noticeably smaller files than JPG at the same quality, which speeds up websites and improves Core Web Vitals. It is the recommended format for modern web images.
How much smaller are WebP files?
WebP files are often 25–35% smaller than an equivalent JPG, and you can push the savings further with the quality slider.
Will WebP work on my website and browsers?
Yes. WebP is supported by all modern browsers including Chrome, Safari, Firefox and Edge. For very old browsers you may want to keep a JPG fallback.
Are my files uploaded to a server?
No. FileFlow runs entirely in your browser using JavaScript — your files are read, processed, and saved on your own device and never travel across the internet. There is literally no server to upload to.
Is it really free? Do I need to sign up?
Yes, it is completely free with no account, no email, and no watermark. Lightweight ads keep the tools free for everyone — there is nothing to install and no limits to unlock.
