JPG to PNG Converter
Some upload systems, design tools, and app stores insist on PNG. This converter turns any JPG into a PNG instantly on your device. Note that PNG stores images losslessly, so the file will be larger than the JPG — that's expected and normal.
100% private — this tool runs in your browser. Your image is never uploaded to any server.

Frequently asked questions
Does JPG to PNG improve quality?
No — the JPG's compression artifacts are already baked in, and PNG simply stores them losslessly from that point on. Convert when a system requires PNG, not to recover quality.
Why is my PNG so much bigger than the JPG?
PNG compresses without discarding data, which suits graphics but is inefficient for photos. A 200KB JPG photo can easily become a 1–2MB PNG. If size matters, question whether PNG is truly required.
Can this make my image background transparent?
No — conversion cannot separate a subject from its background. A JPG has no transparency information to restore; background removal is a different (AI-based) operation.
How do I convert JPG to PNG without losing quality?
JPG to PNG is inherently lossless — PNG stores exactly the pixels the JPG contained, nothing is discarded. This tool does the conversion at full fidelity. Just know PNG can't repair JPG artifacts that already exist; it faithfully preserves the image as-is.
How do I make a JPG background transparent?
Converting to PNG alone doesn't do it — a JPG has no transparency information, so the background pixels are real pixels. You need a background-removal step (an AI tool or manual editing) which then saves as PNG. This converter is the right final step after the background is removed.
What's the difference between JPG and PNG?
JPG uses lossy compression — tiny quality trade for much smaller files — and suits photographs. PNG is lossless, supports transparency, and suits logos, screenshots, and graphics with text or sharp edges. Most upload forms accept both; size-limited forms usually prefer JPG.
How do I convert JPG to PNG on Windows or Mac without software?
This page — it runs in the browser on any OS. On Windows, Paint's Save As → PNG also works; on Mac, Preview's Export does. But the browser route needs no steps beyond drop and download, and never touches your original file.
Why do some websites only accept PNG uploads?
Usually because their system expects transparency support (logos, signatures, stickers) or wants a lossless master it can process without inherited JPG artifacts. Whatever their reason, this converter produces a standard PNG-24 those systems accept.
