How to Convert JPG to PNG (or PNG to JPG) for Free
The upload form only accepts JPG. Your file is PNG. Or vice versa. Here is every way to convert between the two — in your browser, on Windows, on Mac, and on your phone.
The fastest method — works on any device
A browser-based converter handles both directions (JPG→PNG and PNG→JPG) without installing anything. The process is: open the converter, drop or upload your file, click convert, download the result. Total time: under 10 seconds for most images.
Browser-based tools run the conversion locally using your device's processing power — your image is never sent to a server. This makes them faster than cloud-based tools and completely private.

How do I convert JPG to PNG for free?
The easiest way is to use a free online converter — upload your JPG file, click convert, and download the PNG. No software installation or sign-up is needed. Browser-based converters handle the conversion locally on your device, so your image is never uploaded to a server.
Can I convert JPG to PNG on a phone?
Yes. A browser-based image converter works on any device including Android and iPhone. Open the converter in your mobile browser, tap to upload your JPG from your photo library or files, convert, and download the PNG directly to your device.
Does converting JPG to PNG improve quality?
Converting JPG to PNG stops further quality loss — but it cannot recover quality that was already lost when the JPG was compressed. The PNG will be a lossless copy of the current JPG state. If your JPG already has visible compression artefacts (blurring around edges, colour banding), those will remain in the PNG.
Why is my PNG file so much larger than the JPG?
This is expected and normal. JPG uses lossy compression that reduces file size significantly at the cost of some image quality. PNG uses lossless compression that preserves every pixel. For the same photograph, PNG is typically 3–10× larger than a high-quality JPG. This is a trade-off, not a defect.
How do I convert PNG to JPG on a Mac?
On Mac, open the PNG in Preview (the built-in image viewer), go to File → Export, change the Format dropdown to JPEG, adjust quality if needed, and save. This is free and built into macOS. Alternatively, a browser-based converter works on Mac as well without needing to open any specific application.
How do I convert PNG to JPG on Windows?
On Windows 10 and 11, open the PNG in Paint (the built-in app), go to File → Save As, and select JPEG Picture. Alternatively, use Photos app → Edit & Create → Edit → Save a copy, which gives you format options. A browser-based converter is often faster for one-off conversions.
