Frequently asked questions

How do I convert JPG to PNG online?

Upload your JPG file, then click convert. The tool uses the browser canvas to decode the JPG and encode a PNG. Download the result. Everything runs in your browser; no data is sent to any server.

Why convert JPG to PNG?

PNG supports transparency and is lossless, so it is better for logos, graphics with sharp edges, or when you need to edit without losing quality. JPG is better for photos due to smaller file size.

Will the file size increase?

Usually yes. PNG is lossless and often produces larger files than JPG for photos. For graphics with flat colors or transparency, PNG can be efficient.

Are my images sent to a server?

No. Conversion runs entirely in your browser using the canvas API. Your file never leaves your device.

What about transparency?

JPG does not support transparency. When you convert JPG to PNG, the output has no transparency (opaque background). For transparent PNGs, start from an image that already has transparency.

Does it work on mobile?

Yes. Open the tool in your mobile browser, upload a JPG, convert, and download the PNG. No app install required.

Can I convert PNG to JPG?

This tool is for JPG to PNG only. Use a compress or convert image tool for PNG to JPG.

Is quality lost?

No. PNG is lossless. The pixel data is preserved. File size may be larger than the original JPG.

What is the maximum image size?

Limits depend on your device and browser memory. Typical photos (several MB) work without issues.

Can I convert multiple JPGs?

This tool converts one file at a time. For batch conversion, use the tool repeatedly.
