About this tool

PNG is a lossless format that supports transparency and is widely compatible across apps and operating systems. Use this converter when you need a clean PNG export from a JPEG or WebP source, or to re-save an image as PNG — all processing happens locally in your browser.

Preview the original and PNG output, check file sizes, and download with an updated filename. Because PNG is lossless, the output will typically be the same or larger than a JPEG source, but preserves every pixel exactly.

Frequently asked questions

Quick answers about this free online tool.

Upload a JPG, PNG, or WebP file. The image is drawn to an HTML canvas in your browser and exported as PNG — nothing is uploaded to a server. Then preview the result and download.

PNG export from this tool is lossless at the chosen canvas resolution. If the image was scaled down because it was very large, that step reduces pixels — not PNG compression artifacts.

No. Conversion runs entirely in your browser using the Canvas API. Files are not sent to us or stored.

JPEG, PNG, and WebP uploads are supported, up to 25 MB. Very large dimensions are scaled down so the canvas stays within safe browser limits.

If export fails, try a smaller image or a different browser. PNG encoding is widely supported.
