🔁 Image Format Converter

Convert an image between PNG, JPEG and WebP formats, right in your browser. Note that JPEG does not support transparency — transparent areas become white.

What conversion actually does

Your file never leaves the device: the browser decodes it, redraws it on a canvas at its exact original dimensions, and asks the canvas for the new format. Input can be anything your browser can display - PNG, JPEG, WebP, GIF, BMP, AVIF - and output is one of three.

PNG   lossless, keeps alpha, biggest files
JPEG  lossy at quality 0.92, no alpha, white background painted in
WebP  lossy at quality 0.92, keeps alpha, ~25-30% under JPEG

The quality is fixed at 0.92 and there is no slider here; use the Image Compressor when you need to trade detail for bytes. Output dimensions always match the input exactly.

Before you convert

Going to JPEG discards transparency. The canvas is painted white first, so a logo with a clear background gains a white rectangle. Choose WebP to keep the alpha channel.
Animated GIFs lose the animation. Only the first frame is drawn; the result is a still image.
Check the file you get. If a browser cannot encode the type you asked for it quietly writes a PNG instead, which can arrive named .webp.

Converting a JPEG to PNG makes the file bigger without restoring anything - the detail thrown away by the original encoder is gone for good. Any EXIF and colour-profile data is dropped too, so camera settings, date and GPS do not survive the round trip.

Frequently asked questions

How do I convert a PNG to JPG?

Choose the PNG, select JPEG and press Convert; the download arrives as converted-image.jpg. Expect a much smaller file, and remember any transparent area comes back white.

Does converting an image lose quality?

Going to JPEG or WebP does, because both re-encode the pixels at quality 0.92. PNG output is lossless in itself, but it cannot undo losses already baked into a JPEG source.

Which format should I use on a website?

WebP for almost everything - it handles photographs and flat graphics, keeps transparency, and is supported everywhere current. Keep PNG for screenshots and line art you may edit again.
