Frequently asked questions
Why convert JPG to WebP?
WebP gives noticeably smaller files than JPG at the same visual quality, which makes pages load faster and saves bandwidth, especially on mobile.
What quality should I use for WebP?
75–85% works well for most website photos. Use 90% or higher for photography portfolios where detail matters most.
Can WordPress and other CMSs use WebP?
Yes. WordPress, Shopify, Squarespace, Wix and most modern CMSs accept WebP uploads directly.
Are my files uploaded to a server?
No. Conversion runs entirely in your browser via client-side JavaScript, on your own device. Your files never touch a remote server and nothing is stored, so it's a secure, private, no-upload tool for personal photos and confidential data, and it keeps working on slow connections.
Is there a limit on file size or how many images I can convert?
No. Convert as many images as you like, as often as you like. Very large batches only depend on your device's memory, so for hundreds of high-resolution photos, convert them in a few groups.
