Convert JPG to PNG Online — Free
Runs 100% in your browser — your files never leave your device.
JPEG photos are great for sharing, but they don't support transparency and lose a little quality every time they're re-saved. Converting to PNG gives you a lossless image you can place over any background — ideal for logos, screenshots, and graphics cut out of photos. This converter runs entirely in your browser, so your files never leave your device.
How it works
- 1
Drop your JPG file
Drag a JPEG image into the box, or click to browse. Nothing is uploaded — the file stays on your device.
- 2
Convert to PNG
Click Convert. The image is decoded and re-encoded as a lossless PNG locally in your browser.
- 3
Download the result
Save the PNG with one click, or drop another file to convert it — no limits, no sign-up.
About this tool
Converting JPG to PNG
A JPG file jpg trades detail for small files with lossy compression, and carries no transparency. PNG png stores every pixel losslessly and supports full transparency, which makes it the standard for screenshots, logos, and graphics — at the cost of larger files for photographs.. Converting moves your image from the first set of trade-offs to the second: file size shifts with the format's compression style, transparency survives where supported, and pixel data is re-mapped to the target format exactly.
What to check after converting
Open the result and check the two things conversion can change: transparency and size. Transparency is carried over exactly where the target format supports it. Remember the source was already lossy: converting to PNG preserves what arrived, it cannot restore what earlier compression discarded. Your original file stays untouched on your device either way, and the download is a brand-new file.
Frequently asked questions
Will converting to PNG improve the quality?
No conversion improves quality that compression already removed — moving JPG to PNG preserves what arrived and stops further loss, but the artifacts baked into the source stay baked in. The gains are about features: transparency, compatibility, or editing headroom.
Is my image uploaded anywhere?
No — the conversion runs entirely in your browser. The image is processed on your device and never sent to any server, which you can verify by disconnecting after the page loads.
Why convert JPG to PNG instead of the other way around?
The direction follows what the destination needs: graphics, screenshots, and anything needing transparency versus photos and web uploads. Converting back is always available — but each lossy hop re-encodes the image, so keep the highest-quality format as your working copy and convert toward the destination.
