Convert JPG to WEBP
Turn a .jpg photo into a modern WEBP — right in your browser, with a real re-encode via canvas, not a server upload. WEBP is typically 25–35% smaller than an equivalent-quality JPG.

Drop a .jpg file below. Your browser decodes it, then it's re-encoded as a real WEBP on a canvas — previewed here, ready to download.

Why convert JPG to WEBP
WEBP is the format most modern websites use for photos, because it produces meaningfully smaller files than JPG at the same visual quality — faster page loads and less bandwidth. If you're preparing images for a website, converting existing JPGs to WEBP is one of the highest-value, lowest-effort optimizations available.
Edge cases this tool handles
File size
Expect roughly 25–35% smaller output at a visually comparable quality, though the exact savings depend heavily on the specific photo.
Transparency
JPG never has transparency to begin with, so there's nothing to preserve or lose here — the output WEBP is fully opaque, same as the source.
Repeated (generation) loss
Since the source JPG is already lossy-compressed, re-encoding it introduces a small additional generation loss, same as re-saving a JPG as a JPG. For best results, convert from the original/highest-quality source you have rather than a JPG that's already been re-compressed several times.
Frequently asked questions
Does converting JPG to WEBP upload my file anywhere?
No. The image is decoded and re-encoded entirely inside your browser using a canvas — the file never leaves your device or touches a server.
How much smaller will the WEBP file be?
Typically 25–35% smaller than the source JPG at a visually comparable quality, though this varies a lot by image content — photos with lots of fine detail or noise compress less than smooth, simple images.
Will I lose quality converting an already-compressed JPG?
A small amount, yes — since the source JPG is already lossy, re-encoding it adds a further (usually minor) generation loss, the same as re-saving any JPG. Converting from the original source, if you have it, avoids this.
Is WEBP widely supported?
Yes — every major browser has supported WEBP natively for years, and it's now the default image format on most modern websites.
