Why convert PNG to JPG?

For photographic content, JPG is dramatically smaller than PNG — often 5–10× — because PNG's lossless compression is a poor fit for photos. Keep PNG for screenshots, UI graphics and anything with sharp edges or transparency; convert to JPG when the content is a photo and file size matters.

Conversion happens entirely in your browser — no upload, no queue, no watermark. Drop in as many files as you like and download them individually or as a zip.

Frequently asked questions

What happens to transparent areas?
JPG has no alpha channel, so transparent pixels are flattened onto a background color. This tool warns you when the source has transparency and lets you pick the background color (white by default).
Are my images uploaded anywhere?
No. Conversion happens inside your browser using the canvas API and a Web Worker — files never leave your device. There is no upload step, no queue and no file size limit beyond your machine's memory.
Is EXIF metadata kept in the converted image?
No — and that's a feature. Re-encoding through the canvas strips all metadata: GPS location, camera model, timestamps and color profiles. The output contains pixels only, which is usually what you want before sharing an image publicly.
Can I convert many images at once?
Yes. Drop or paste any number of files; each is converted in the background with its own progress and download button, and you can grab everything at once as a .zip archive.
Why did my image get re-compressed even converting PNG to PNG?
The converter always decodes to raw pixels and re-encodes, which is also how metadata gets stripped. For lossless targets (PNG, and GIF within its 256-color limit) the pixels stay identical; for JPEG and WebP the quality slider controls the trade-off.
