How to use it
- 1Drag your JPG image in, or click to upload it.
- 2Check that the output format is set to WebP. (WebP is the default on this page.)
- 3Use the quality slider to balance file size and clarity. Around 80% is usually indistinguishable from the original.
- 4Press Convert and the size reduction from the original JPG will appear. Hit download to save — done!
Handy tips
- For web optimization, try testing in the 75–85% quality range. You can typically cut file size by 30–50% without any noticeable difference in most photos.
- JPG has no transparency, so converting to WebP won’t add it. WebP works best for solid, opaque photo images.
- If you need the converted WebP to work in older environments too, keep the original JPG ready as a fallback.
Same quality, smaller size — the WebP compression edge
JPG is an old and excellent photo format, but its compression method was set more than two decades ago. WebP uses a newer compression technique that packs quality that looks virtually identical to the eye into a smaller file. In practice, converting a photo to WebP at the same quality setting often makes it roughly 25–40% lighter than JPG.
That difference looks minor on a single image, but it adds up fast across dozens or hundreds. For a store crammed with product photos, a photo-heavy travel blog, or a gallery-style portfolio, the total page weight can drop by nearly half. Keeping the quality while shedding only the transfer size — that's the core benefit of converting JPG to WebP.
Optimizing blog and store images in practice
When putting images on the web, a two-step approach pays off. First resize the image's width to the size it actually displays at (usually 1200–1600px), then convert it to WebP with this tool at around 80% quality. That combination usually strips a lot of size off the original with no visible drop in quality.
If a single blog post has several photos, optimizing the key image first — the cover at the top of the post — is the priority. That's the image that appears large the moment a visitor opens the page, so making it light is what makes loading feel fast. For a store, standardizing the thumbnails in your listings to WebP makes scrolling far smoother. This tool processes one image at a time, but converting and uploading your most important images first still helps page speed.
When it's better to keep JPG
WebP isn't always the answer. When you're emailing files back and forth, embedding them in a document, or you don't know what software the recipient uses, JPG is the safer choice. Older Office suites, legacy viewers, and some apps still can't open WebP. If it's a "not sure who's going to open this" situation, the universally supported JPG is the easier pick.
So in practice it helps to split by purpose. Upload WebP to web spaces you control — your own website, blog, or store — to gain speed, and keep JPG for files you'll send to someone or submit somewhere. If you build the website yourself, you can also use a picture tag to serve WebP first and fall back to JPG for browsers that don't support it.
Frequently asked questions
It depends on the image, but at the same quality setting WebP is typically 25–40% lighter than JPG. The more detail in the photo, the bigger the savings.
You control it directly with the quality slider. At 80% or above, the result is hard to tell apart from the original JPG by eye. That said, turning an already lossy JPG into WebP (another lossy format) adds a tiny bit of degradation, so start from the highest-quality original you can.
No. JPG has no transparency to begin with, so converting to WebP won’t create a transparent background. If you need transparency, convert to PNG first and then remove the background.
It depends. Messaging apps that support photo sending will often send WebP fine, but the preview may not render on some devices or app versions. Document programs like Word still have many versions that block WebP insertion. To be sure it opens in those places, JPG is the safe choice. WebP shines when you're uploading to your own website or blog.
No, the original stays untouched. You only receive the newly converted WebP, and since processing happens entirely on your device, nothing leaves it.
