About
What JPG to WebP does
Convert JPG photos to WebP, the format Google made for the web: smaller files at a similar quality, so pages load faster. Set the quality and see each file's real saving before you download.
Everything happens on your own machine: the file is decoded, processed and re-encoded by your browser, and never leaves your device. There is no upload, no queue and no account.

Every file shows its size before and after, so you know what WebP bought you before you download.
-
Works in every browser
Chrome, Edge, Firefox and Safari all show WebP, and WordPress takes it as an upload.

Nothing is uploaded
Your photos are converted by your own browser and never leave your device.

Questions
Frequently asked
How do I convert JPG to WebP?
Drop the JPG files here. Each is converted to WebP straight away; download them one at a time or together as a ZIP. Nothing is uploaded.
How much smaller will my images be?
It depends on the photo, and each file shows its real size before and after. Google measured WebP 25–34% smaller than JPG at the same quality; a lower quality setting saves more.
Does every browser support WebP?
Every current one does: Chrome, Edge, Firefox, and Safari since version 14.
Can I use WebP in WordPress?
Yes. WordPress has accepted WebP uploads since version 5.8, so the converted files go straight into the media library.
What quality should I use?
80, the default, suits most photos on a website. Try 60 to 70 for thumbnails, and go higher for photography you want pin-sharp.
Should I keep my JPGs?
Yes. WebP is for publishing; keep the originals for printing, editing, and anywhere that asks for a JPG.
Are my images uploaded?
No. They are converted inside this page, on your device, and saved straight back to it. Nothing is sent to a server, so there is no copy anywhere else to delete.
