The web's photographic workhorse.
JPG uses lossy compression and is the right pick for photographs and natural scenes when file size matters.
- Smallest size for photos
- Universal compatibility
- No transparency
- Re-saves degrade quality
JPG → WebP
Convert JPG to WebP.
Drop a JPG (or many) and we'll convert each one to WebP right here in your browser. WebP gives you JPG-class compression with alpha-channel support — the modern default for web imagery.

Why convert JPG to WebP?
WebP at the same visual quality is typically 25–35% smaller than JPG. For sites where page weight matters, it's almost always the right swap.

Are my images really not uploaded?
Correct. The entire conversion pipeline runs in your browser using the Canvas API and a couple of small WASM/JS libraries for less-common formats like TIFF. There's no server endpoint that accepts your image data — open DevTools and watch the Network tab if you want to verify it yourself.
Is there a file-size limit?
No hard limit. The practical ceiling is your device's available memory — modern laptops handle 100MB+ images comfortably. Mobile devices vary; if a conversion fails on a large image, try resizing it first.
Why does my SVG-to-PNG conversion not match the original at scale?
We rasterize SVGs at their intrinsic size (or 1024px if unspecified). To get a higher-resolution PNG, use Resize → By percent and bump it up before converting.
Why is my converted PNG bigger than the JPG I started with?
PNG is lossless and JPG is lossy — for photographs, JPG will always be smaller. If you want to keep file size down, target WebP instead, which gives you JPG-class compression with optional transparency.
Do you support batch conversion?
Yes. Drop in as many files as you like and hit Convert all. Download them individually, or grab the whole batch as a single ZIP.
Can I convert TO an animated GIF?
Right now we encode the first frame as a single-frame GIF. Multi-frame GIF and animated-WebP encoding is on the roadmap.
