Supports: WEBP
.webp images onto the page or click "+ Add Files" to browse. Batch upload is supported — queue dozens of images and convert them in one pass. Animated WebP files convert to a JPG of the first frame.Google released WebP in September 2010 as a more efficient web image format — lossy WebP averages 25–34% smaller than equivalent-quality JPEG, and lossless WebP is about 26% smaller than PNG. That efficiency is why "Save Image As" from Chrome, Edge, Opera, and Android browsers increasingly hands you a .webp file. The problem is downstream: many printing services, document editors, older content management systems, and consumer photo apps still don't accept WebP, so a one-step conversion to JPG is the most reliable way to make the image actually usable.
.webp. Windows Photos handles it, but older Photoshop versions (pre-CC 2022 23.2), legacy Microsoft Office builds, and many photo-frame apps reject the extension outright. JPG opens everywhere.| Property | WebP | JPG |

The table below is for a typical 12-megapixel photo source (~3 MB lossy WebP). Actual JPG output varies with image content, but the preset → JPEG-quality mapping is fixed.
| Preset | JPEG quality | Approx output | Best for |
|---|---|---|---|
| Very High (default) | ~92 | 80–100% of source | Print, archival, photo editing |
| High | ~85 | 50–70% of source | Web galleries, social uploads |
| Medium | ~75 | 30–45% of source | Email attachments, blog images |
| Low | ~60 | 15–25% of source | Quick previews, thumbnails |
| Specific file size | Auto-tuned | Exact target KB/MB | Hitting a hard cap (e.g., 1 MB upload) |
| WebP source | JPG output | Notes |
|---|---|---|
| Opaque WebP (no alpha) | 1:1 visual match | Only re-compression loss applies |
| Lossy WebP with alpha | Flattened on white background | Choose WebP to PNG to keep transparency |
| Lossless WebP with alpha | Flattened on white background | Lossless → lossy conversion will add JPG artifacts in flat regions |
| Animated WebP | First frame only, alpha flattened | Use a video converter if you need motion |
Yes, but typically only a little. Lossy WebP is already lossy, and JPG re-encoding adds a second pass of lossy compression. At the Very High preset (≈92 JPEG quality), the result is visually indistinguishable from the source for most photos. Lossless WebP → JPG is more visible because you're moving from a lossless source to a lossy format — flat color regions and sharp edges (text, logos, screenshots) will show JPEG ringing artifacts. For those sources, WebP to PNG is the better choice.
That's expected. WebP's lossy compression averages 25–34% smaller than JPEG at equivalent quality (per Google's published benchmarks). So a 1 MB WebP commonly produces a 1.3–1.5 MB JPG at the Very High preset. If you need a smaller JPG, drop the preset to High or Medium, or use the Specific file size option to target a cap.
JPG has no alpha channel, so every transparent pixel must be replaced with an opaque color. The default fill is white. If you need to preserve transparency for layered design work, use WebP to PNG instead — PNG keeps the alpha channel intact.
Yes, but the output is a single still JPG of the first frame. JPG doesn't support animation. If you need to keep the motion, convert the animated WebP to MP4 or GIF using a video-style converter; if you only need a poster image, this tool is fine.
.webp instead of JPG?Websites that serve modern image formats often deliver WebP to Chrome, Edge, Opera, and Android because the browser advertises WebP support in its Accept header. The "Save Image As" dialog saves the file in whatever format the server sent, so you get the .webp extension even though the on-screen image looked like a normal photo. There's no Chrome setting to force JPG saving — converting after the fact is the standard fix.
The practical limit is upload size and connection speed. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up wall, no per-day cap, and no watermark.
.webp to .jpg?Renaming the extension does not convert the file — the bytes inside are still WebP-encoded, so any program that doesn't already understand WebP will fail to open it (often with a misleading "corrupt JPG" error). A real conversion re-encodes the pixels using JPEG compression so the file is a valid JPG that every viewer can read.
If your destination accepts WebP, keeping it as WebP gives you smaller files at the same visual quality — try compress WebP instead. Convert to JPG only when the receiving app or service (printer, marketplace, older editor, email recipient on a legacy client) actually requires a JPG. For the reverse direction, see JPG to WebP.
Conversion runs on our servers. Files stay on your device for the duration of the job and are not retained after you close the tab. There's no account, no email field, and nothing to opt out of.
