About JPG to PNG
Drop in a JPG (or WebP, GIF, BMP, or other image) and this tool converts it to a lossless PNG right in your browser. It draws the image to a canvas and exports a clean PNG, preserving any existing transparency, then shows you the original size, the PNG output size, and the pixel dimensions.
It is completely free with no sign-up, no watermarks, and no limits. Your image never leaves your device: all the work happens locally in your browser, and nothing is uploaded to a server. When you are happy with the result, just click Download PNG.
Frequently asked questions
- Is this JPG to PNG converter free?
- Yes, it is completely free with no sign-up, no watermarks, and no file limits. You can convert as many images as you like.
- Are my images uploaded to a server?
- No. The conversion happens entirely in your browser using an HTML canvas. Your image is never uploaded, stored, or sent anywhere, so it stays private on your device.
- Does the PNG keep transparency?
- Yes. PNG output is lossless and preserves any transparency present in the source image. Note that standard JPG files have no transparency to begin with, so converting a JPG simply produces an opaque PNG.
- Why is my PNG file larger than the original JPG?
- PNG uses lossless compression, while JPG throws away detail to shrink files. So a photo saved as PNG is often bigger. The tool shows the exact size change so you can decide which format suits your needs.
- What image formats can I convert to PNG?
- Any image your browser can open, including JPG, JPEG, WebP, GIF, and BMP, can be converted to PNG. Just choose the file and the tool handles the rest.
- Will converting change my image quality?
- No. PNG is a lossless format, so the pixels are preserved exactly as drawn. Converting a JPG to PNG will not add quality back, but it also will not introduce any new compression loss.
