Why convert JPG to WebP in your browser instead of online?

Converting JPG to WebP is almost always about shipping a lighter website, which means the workflow is usually repeated across many images — a poor fit for uploading one file at a time to a remote converter. NearIMG re-encodes to WebP locally, so a batch of images can be converted back to back without a server in the loop.

How it works

1. Drop in JPG files — this tool is built for batches.
2. Set the WebP quality (80% by default) and watch the measured ≈ size of each file update.
3. Click Convert — everything re-encodes to WebP locally and downloads, as a ZIP for batches.

The usual motive here is page weight: re-encoding JPGs to WebP typically cuts a meaningful share of their size at comparable visible quality, which adds up fast across a site's image folder. Since JPG→WebP is a lossy-to-lossy re-encode, two practical rules: pick the quality by watching the live measured size rather than guessing, and keep the JPG originals as your source of truth — regenerate the WebP from them when needed instead of re-encoding WebP→WebP.

How much smaller is WebP?

WebP is typically 25–35% smaller than JPG at a similar quality.

Do browsers support WebP?

Yes — every current browser displays WebP images.

Should I delete the JPG originals afterwards?

Keep them. The WebP is a lossy re-encode — a delivery copy. If you later need a different size or quality, regenerating from the JPG original avoids stacking a second generation of loss.
