Why convert JPG to WebP?
If you run a website, WebP is the easy win: swapping JPGs for WebP typically cuts image weight by a quarter to a third with no visible change, so pages load faster and cost less bandwidth.
Two caveats. WebP isn’t universally supported by older software, so it’s a web format, not a “send it to anyone” format. And re-encoding a JPG is lossy-on-lossy — a small extra quality cost on top of what the JPG already lost.
What you gain
- Typically 25–35% smaller than the JPG at the same quality
- Faster web pages, less bandwidth
- Keeps a quality slider so you control the trade-off
What you lose or trade
- Re-encoding a JPG loses a little more quality (lossy on lossy)
- Not for recipients on older apps/email clients that mishandle WebP
The honest recommendation
Great for your own website; if you’re sending the file to a person, keep the JPG — and remember re-encoding adds a little loss on top of what the JPG already discarded.
Measure it on your own image with the format advisor →JPG to WebP: questions
How much smaller is WebP than JPG?
Usually 25–35% at the same visible quality, though it varies by image. Our format advisor measures the exact saving on your specific file so you’re not guessing.
Does re-encoding a JPG to WebP lose quality?
A little. The JPG is already lossy, and WebP re-compresses it, so some extra detail goes. At high quality it’s hard to see, but it’s not free — keep the original JPG if you might need it.
Should I send WebP files to people?
For your own website, yes. For sending to someone, JPG is safer — a few older apps and email clients still render WebP poorly.
