Format conversion
Convert PNG to JPG
Drop your PNG files below. Conversion happens on your device — nothing is uploaded, and there is no limit on how many you convert.
How to convert PNG to JPG
- Drop one or more PNG files onto the panel.
- Adjust the quality if JPG is a lossy format.
- Download the converted files individually or as a ZIP.
Why convert PNG to JPG?
A PNG photograph is typically five to ten times larger than the same image as JPEG, because PNG is lossless and photographs contain no repeating patterns for it to exploit.
What is lost in the conversion?
Transparency is lost — JPEG has no alpha channel, so transparent pixels are filled with a background color. Fine detail is discarded at quality settings below about 0.85.
How much smaller will the file be?
A 3 MB PNG photo typically becomes 250–400 KB as JPEG at quality 0.8.
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 PNG to JPG conversion lossy?
Yes. JPG is a lossy format, so some image data is discarded. Use a high quality setting when the source matters.
Will I lose transparency?
Yes. JPG has no alpha channel, so transparent areas are filled with a background color you choose — white by default.
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.
