Convert a PNG to a JPG (JPEG). The result is lossy, transparent areas turn white, and the pixel size stays the same.
If this tool isn’t working as expected, please take a screenshot of the error and report the problem here so we can investigate and improve it.
Re-encodes a PNG as a JPG at a fixed 90% quality and keeps the pixel size. JPG is lossy, so photos and scans usually shrink a lot, but flat graphics with few colors often don't: a 2.3 KB logo-style PNG came out as a 3.6 KB JPG in a test.
The conversion runs in your browser, so the PNG is not uploaded.
JPG has no transparency channel. Wherever the PNG is transparent, this converter fills the area with solid white before encoding, so a logo saved on a transparent background will have a white background in the JPG.
Select a PNG file from your device.
Conversion starts as soon as the file is chosen. The PNG is re-encoded as a JPG at a fixed 90% quality, and transparent areas are filled with white.
The original and the JPG appear side by side, so you can check the result before saving.
Save the file. It is named like photo_converted_codittools.jpg.
Some forms and marketplaces accept JPG only. Convert the PNG, check the preview, since transparent areas become white, then upload.
A photo saved as PNG is far bigger than the same photo as JPG: a 3.7 MB PNG of a 1440×960 test photo came out at 608 KB.
If the JPG is still over a size limit, run it through the Image Compressor.

Problem
Solution
JPG compression can blur text and sharp edges, so a screenshot usually looks cleaner kept as PNG.
JPG cannot store transparency, so this converter fills those areas with white. There is no background-color option; for a different color, flatten the PNG in an image editor first.
There is no quality setting. JPG is lossy, so fine detail and sharp edges can show artifacts, and converting the JPG back to PNG won't restore them.
Both usually shrink a PNG photo, but they treat transparency differently.
| PNG to JPG | PNG to WebP | |
|---|---|---|
| Transparency | Lost - transparent areas become white | Kept - the alpha channel carries over |
| Where it opens | Practically everywhere | Current browsers and most modern tools; some older editors and upload forms reject it |
| Best for | Photos, and any place that requires JPG | Logos and UI images that must stay transparent |
Which should you use?
If the PNG has a transparent background you want to keep, convert it to WebP. If it is a photo, or the destination only takes JPG, use JPG.
Transparent areas turn white and quality is fixed at 90%. These answers explain what that means for logos, photos and sets of PNGs.
It becomes solid white. JPG cannot store transparency, and this converter has no option to pick another color. To get a brand color or any color other than white, put that background behind the image in an editor before converting, or use PNG to WebP if you only need a smaller file that stays transparent.
Yes, slightly. JPG is a lossy format and this tool saves at a fixed 90% quality with no slider. For photos the difference is rarely visible; text, thin lines and sharp edges are where artifacts show. Keep the PNG if you may need the original again.
Flat graphics with few colors, such as logos and icons, are stored very compactly as PNG, while JPG adds data to approximate sharp edges. A 2.3 KB test PNG became a 3.6 KB JPG. JPG saves space on photographs, not on flat artwork.
Each run here converts a single PNG. The Bulk Image Converter takes many PNG files and returns JPGs in one ZIP. It also fills transparent areas with white, so transparent PNGs look the same as they do here.
