JPG to PNG Converter
Convert JPG (or any image) to a lossless PNG, right in your browser.
Convert JPG to PNG without uploading
This JPG to PNG converter decodes your JPEG and re-saves it as a PNG — a lossless format that supports transparency and keeps hard edges crisp. The whole conversion happens on a canvas inside your browser, so the file is never sent to a server and nothing is stored anywhere.
When PNG is the right choice
PNG is ideal for screenshots, logos, line art and anything with sharp text, because it never adds the blocky artefacts that JPEG compression can. The trade-off is a larger file for photographs. The tool shows the original and new file sizes so you can see the difference before you download.
How to use the JPG to PNG Converter
- Choose an image. Pick a JPG (or any image) from your device.
- Let it convert. The PNG is generated instantly on a canvas in your browser.
- Check the preview. Confirm the image looks right and compare the file sizes.
- Download. Save the .png file straight to your device.
Frequently asked questions
Is my image uploaded to convert it?
No. The conversion runs entirely in your browser with the Canvas API; the file is never uploaded, stored or seen by any server.
Will the PNG be bigger than the JPG?
Usually, yes, for photographs — PNG is lossless, so it stores every pixel exactly. For screenshots and graphics the difference is small and the quality is better.
Does converting improve the quality?
It cannot add back detail that JPEG already discarded, but it prevents any further loss. From here on the image stays pixel-perfect.
Can I convert PNG-unfriendly formats too?
The tool accepts any image your browser can open (JPG, WebP, GIF, BMP and more) and outputs a standard PNG.
