Convert JPG to WebP
Convert JPG to WebP to trim photos for the web. Batches run up to 10 files, 20MB each. The conversion runs locally, nothing is sent out.
WebP usually produces a smaller file than JPG at a similar visual quality, which is why sites convert photos for faster pages. This conversion is a second lossy pass on top of the JPG's existing compression, so start from the sharpest JPG you have, not a resaved copy.

JPG vs WebP
JPG
JPG keeps files small and opens on virtually any device or app, which is why it became the default photo format. That convenience costs it real detail every time it gets re-encoded.
WebP
WebP usually lands lighter than JPG at a similar visual quality, encoded here at quality 92, and it still supports transparency if the source needs it.
Why convert JPG to WebP
The honest reason to make this conversion is page speed. WebP usually renders a lighter file than JPG at a similar visual quality, and a lighter photo loads faster on a mobile connection. That is the entire case for doing this, nothing more. What it will not do: convert cannot repair a soft or heavily compressed JPG, because the swap is a second lossy pass stacked on the first one, so any existing artifacts carry straight through and can pick up a touch more softness. It also will not help outside a browser context. Older editing software, some print workflows, and a handful of legacy systems still choke on WebP. If a file is heading to a print shop, a client on unfamiliar software, or an archive, keep the original JPG instead. Reserve the WebP copy for images that will only ever be displayed on your own website.

FAQ
Will the file get smaller?
Usually yes. WebP typically produces a smaller file than JPG at a similar visual quality, which is why sites use it to speed up pages.
Does this improve quality?
No. The conversion is a second lossy pass on top of the JPG's existing compression, so quality can never improve, only stay close or slip slightly. Start from the highest quality JPG you have.
Can I convert several JPG files at once?
Yes, up to 10 JPG files per batch, 20MB each.
Does this converter let me pick a WebP quality level?
No, there is no quality slider here. The format simply changes from JPG to WebP, unlike a dedicated compression tool that offers separate quality levels.
