Convert PNG images to JPG format online. Reduce file size while maintaining high image quality.
PNG's lossless compression is ideal for logos and graphics with transparency, but it produces much larger files for photographs than a lossy format needs to. This tool re-encodes your PNG as a JPG at a fixed 90% quality setting, which keeps visual quality close to the original while cutting file size - useful for email attachments, upload forms, and platforms that reject or discourage PNG.
The conversion runs entirely in your browser; the file never reaches a server.
PNG files carry lossless compression, which keeps every pixel exact but produces bigger files than most upload forms, email clients, or listing platforms want. Converting to JPG trims the file down substantially for photos and scans where pixel-perfect fidelity isn't the point.

Best For
Source File
logo.png - 512x512, transparent background, 24.6 KBResult
logo.jpg - 512x512, black background, about 16 KB (about 35% smaller)The exact size reduction depends heavily on the image - flat, low-detail graphics like this one compress less dramatically than busy photographs, since PNG already compresses flat color well. Note the transparent background became solid black in the JPG, not white.
Convert a PNG photo to JPG before attaching it to an email that's close to the provider's size limit.
Some upload forms and marketplaces only accept JPG - convert here rather than re-exporting from the original design file.
Convert a folder of PNG photo exports to JPG to save disk space, when pixel-perfect losslessness isn't needed.
Problem
Solution
JPG has no transparency channel. Wherever your PNG was transparent, the JPG fills that area with solid black, not white. If you need a white or specific-color background, flatten it in an image editor first, or use WebP or PNG instead, both of which preserve transparency.
Problem
Solution
JPG's lossy compression tends to blur fine text and put visible artifacts around sharp edges. A screenshot with UI text usually stays sharper as PNG - use the Image Compressor to shrink the PNG without switching formats.
Problem
Solution
This tool exports at a fixed quality level with no slider and no background-color choice. If you need control over either, edit the image in a design tool before converting.
Since the tool always fills transparent areas with black, open the PNG in an editor and add a white (or brand-color) background layer before converting if you need a specific background color in the JPG.
The 90% quality setting keeps visual quality high but doesn't minimize file size on its own. Run the result through the Image Compressor for a smaller file if the JPG is still over a size limit.
Since this conversion is lossy and one-directional, hold on to the source PNG in case you need a different background color or decide JPG isn't the right format after all.
The tool always exports at a fixed 90% JPG quality. There's no control to trade off file size against visual quality.
Transparent areas always convert to black. There's no option to pick white or another color during conversion.
This page converts a single PNG per run. For multiple files, use the Bulk Image Converter, which handles PNG to JPG in batch and returns a ZIP.
Both shrink a PNG's file size, but only WebP keeps transparency. Pick based on whether the image needs a transparent background.
| PNG to JPG | PNG to WebP | |
|---|---|---|
| Transparency | Lost - transparent areas become solid black | Preserved - alpha channel carries over |
| Compatibility | Universal - every platform, editor, and viewer accepts JPG | Very broad, but a handful of older tools still lack support |
| Best for | Photos and images with no transparency | Logos, icons, and graphics that need to keep a transparent background |
Which should you use?
If your PNG has a transparent background you want to keep, convert to WebP instead. If it's a flat photo with no transparency, either format works - JPG has the wider compatibility.
The most common surprise with this conversion is what happens to a transparent background - JPG has no transparency channel, so the FAQ below explains exactly what fills that space.
Yes, JPG uses lossy compression which slightly reduces quality compared to PNG. This tool exports at a fixed 90% quality setting, so the difference is barely visible for most images. The benefit is a smaller file size, ideal for web use and email attachments.
Yes. JPG does not support transparent backgrounds. When converting a PNG with transparency to JPG, the transparent areas are automatically filled with solid black - there is no option to choose a different background color. Use WebP or keep PNG if you need transparency, or flatten the image to your preferred background color before converting.
Yes. CoditTools processes image conversions entirely in your browser using JavaScript. Your files are never uploaded to any server, keeping your images completely private and secure.
Yes. Use the Bulk Image Converter tool on CoditTools to convert multiple PNG files to JPG in a single batch. Upload all files, select JPG as output, and download all converted images in one ZIP file.
PNG is a lossless format that supports transparency, making it ideal for logos and graphics. JPG is a lossy compressed format best for photographs where smaller file size matters. PNG files are larger; JPG files are smaller and more web-friendly.
Usually not. JPG's lossy compression tends to blur fine text and create visible artifacts around sharp edges, which is exactly what a screenshot is made of. Screenshots and other flat, text-heavy images generally stay sharper as PNG - use the Image Compressor if the PNG file size is the concern.
