Format conversion
Convert JPG to PNG
Drop your JPG files below. Conversion happens on your device — nothing is uploaded, and there is no limit on how many you convert.
How to convert JPG to PNG
- Drop one or more JPG files onto the panel.
- Adjust the quality if PNG is a lossy format.
- Download the converted files individually or as a ZIP.
Why convert JPG to PNG?
Converting to PNG gives you a lossless container and an alpha channel, which is what you need before editing or before placing an image over a colored background.
What is lost in the conversion?
Nothing is lost, but nothing is recovered either — JPEG compression artifacts already in the file are preserved exactly. The file usually grows substantially.
How much smaller will the file be?
A 400 KB JPEG photo typically becomes 2–4 MB as PNG.
File size depends heavily on image content. Photographs, screenshots and line art compress very differently, so treat these figures as typical rather than guaranteed.

Frequently asked questions
Is JPG to PNG conversion lossy?
No. PNG is lossless, so every pixel of the decoded source is preserved exactly.
Will I lose transparency?
No. PNG supports an alpha channel, so transparency is preserved.
Can I convert several files at once?
Yes. Drop as many as you like and download the whole batch as a ZIP.
Is there a file size limit?
No server-imposed limit. The ceiling is your device's memory, which is far above what upload-based converters allow.
Does it add a watermark?
No. No watermark, no daily cap and no signup.
Are my images uploaded?
No. Decoding and encoding both use your browser's built-in codecs on your own device.
