Convert JPG to WebP Online — Lighter Photos for the Web
A folder of camera JPEGs can drown a webpage. WebP often beats JPEG at the same visual quality, which is why this page exists: one job, JPG in, WebP out, quality slider, rename, done — on your machine.

When JPG → WebP is the right job
You are replacing hero JPEGs on a marketing page and want a smaller still without opening Photoshop.
A gallery export is all .jpg and the host now prefers .webp.
How the conversion runs on this page
Upload photos, set quality, convert, rename to match your CMS slug if you like.
Keep the original JPEG as archive. WebP here is a delivery copy, not a negative.
Quality, limits, and honesty
A second lossy encode on top of JPEG can add softness. Stay high on the slider for faces and product shots.
If a partner still cannot open WebP, send the JPEG or convert WebP back to JPG with the sibling tool.
Privacy
Your JPG file is decoded in this tab. We do not upload it to convert it to WebP.
If a related job is next — compress a PDF, flatten another image, or switch pairs — use the links on this page so the file stays on your device the whole way.

FAQ
Is WebP better than JPG for photos?+
Often yes for the same perceived quality at a smaller size. Always A/B the actual files — night shots and tiny thumbnails can surprise you.
Does this upload my photos?+
No. Encoding is local.
Can I pick quality?+
Yes. Use the quality control before you download.
Will EXIF GPS stay in the WebP?+
Canvas re-encode typically strips camera metadata. That is usually what you want for a public page; keep the original JPG if you need the EXIF.
Is it free?+
Yes, with no account required for this conversion.
