Will re-encoding hurt quality?

There’s a small generational loss, but at a high quality setting it’s imperceptible while the file gets smaller.

Should I use WebP everywhere?

Use it for the web. For maximum compatibility with old apps, JPG is still the safer bet.

Can I batch-convert photos?

Yes — drop many files and download them all as a ZIP.

Why convert JPG to WebP?

WebP compresses photographs more efficiently than JPG, so you get a visibly similar image in a smaller file — ideal for websites where every kilobyte affects load time.

When WebP is the right choice

Use WebP for images you serve on the web. For email attachments or legacy software that can’t read WebP, stick with JPG instead.

Quality & compatibility notes

This is a re-encode from an already-lossy JPG, so keep the quality high to avoid stacking compression artifacts. The result is smaller than the original at equivalent visual quality.
