Convert PNG to JPG
Photographic images saved as PNG carry a huge size penalty for no visual benefit. Converting to JPG (encoded with MozJPEG here) shrinks them drastically. Transparency is flattened onto a background color of your choice, since JPG has no alpha channel.

About the formats
PNG
PNG is a lossless format with full transparency support, ideal for screenshots, UI graphics, logos, and any image with sharp edges or text. The trade-off is size: photographic content stored as PNG is much larger than JPEG, WebP, or AVIF.
JPG
JPEG is the most universally supported image format in existence — every browser, app, device, and upload form accepts it. It uses lossy compression tuned for photographs. This converter encodes JPEG with MozJPEG, which squeezes out noticeably smaller files than standard encoders at the same visual quality.
Frequently asked questions
Are my PNG files uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly codecs — your files never leave your device. After the first visit the converter even works offline.
Can I convert many files at once?
Yes — add as many files (or whole folders) as you like, convert them in one batch, and download everything as a single ZIP. There are no file-count or size limits.
Will I lose quality converting PNG to JPG?
You stay in control: JPG quality is adjustable in the options panel, and the defaults are tuned to be visually indistinguishable for typical images. You can re-convert with different settings instantly.
