Frequently asked questions

What happens to transparent areas?

JPG cannot store transparency, so transparent pixels are filled with solid white during conversion. If you need to keep transparency, stay with PNG or convert to WebP instead.

Can I control the JPG quality?

This converter uses a high default quality (92%) that suits screenshots, documents and web graphics. For precise control over output size, use the image compressor after converting.

Is the conversion really private?

Yes. Everything runs in your browser with the canvas API. The file is read from disk, converted in memory and handed straight back to you — no upload, no storage, no logs.

Will the JPG look identical to the PNG?

Visually it will be near-identical at the default quality. JPG is a lossy format, so a few bytes differ, but at 92% quality the difference is imperceptible in normal use.

About this tool

PNG files are great for graphics but bulky for sharing. This free converter turns them into compact JPGs that upload faster, fit email attachment limits, and open identically everywhere — no software to install, no watermark, no signup. Because JPG has no transparency channel, transparent regions are filled with a clean white background automatically, which is exactly what most galleries, marketplaces and office software expect. Decoding respects EXIF orientation where present, and encoding uses a high default quality setting so text, edges and gradients stay crisp. The entire conversion happens inside your browser on your own hardware: your images are never uploaded to a server, never stored, and never seen by anyone but you, which makes the tool safe for confidential screenshots, contracts and internal documents. Drop a file to convert it instantly, preview the result, then download or run it through the image compressor if you need an exact target size.
