How to use the PNG to JPG Converter
Step 1: Drag a PNG image onto the upload box, or tap it to choose a file.
Step 2: The tool converts it automatically and shows a preview. Transparent areas are filled with white.
Step 3: Use the Quality slider to balance file size and sharpness. The default is 90 percent.
Step 4: Check the file sizes and the preview of the new JPG.
Step 5: Press Download JPG to save it.
Features and benefits
Transparency handled
JPG cannot store transparency, so the tool paints a white background first. You are told when your PNG contained transparent areas.
Adjustable quality
Choose a higher quality for logos and text, or a lower one for smaller photographs.
Before and after
Both previews and file sizes are shown so you can decide whether the JPG is what you need.
Private conversion
The PNG is converted by your browser and is never uploaded.
Safe file checks
The tool verifies that the file really is a PNG before processing it.
Why transparent PNGs get a white background
PNG supports an alpha channel, which means some pixels can be fully or partly see-through. JPG has no alpha channel at all. If a converter did nothing special, transparent pixels would turn black or arbitrary colours. This tool first fills the canvas with white and then draws your PNG on top, so transparent areas become white, which is the most common expectation.
If you need to keep the transparency, do not convert to JPG. Keep the PNG, or use WebP, which also supports transparency.
When to convert PNG to JPG
JPG is designed for photographs and smooth gradients, so photographic images saved as PNG often become dramatically smaller. It is a weaker choice for screenshots with small text, logos and line art, where JPG can leave faint blocky artefacts around sharp edges. For those, use a high quality setting of 90 to 100 percent, or keep the PNG.
Quality and file size
The default quality of 90 percent keeps most images crisp. Lowering it makes the file smaller at the cost of detail. If a flat-colour graphic becomes larger as a JPG than it was as a PNG, that is normal: PNG compresses flat colours very efficiently. In that case keep the PNG.
Example use cases
Shrinking screenshots
Photographic screenshots saved as PNG are often much smaller as JPG.
Meeting upload requirements
Some forms and marketplaces accept only JPG images.
Sharing photos
JPG is understood by virtually every device, app and print service.
Flattening graphics
Place a logo or illustration on a plain white background for documents and email.
Frequently asked questions
Why is the background of my JPG white?
JPG cannot store transparency, so transparent areas of the PNG are filled with white before saving.
Can I keep a transparent background?
Not in a JPG. Keep the file as PNG, or convert to WebP, which supports transparency.
Will text and logos look blurry?
JPG compression can leave small artefacts around sharp edges. Use a quality of 90 to 100 percent to minimise them, or keep the PNG for logos and text.
Is my PNG uploaded anywhere?
No. Conversion takes place entirely in your browser.
What is the maximum file size?
25 MB per image. Extremely large images may be too big for your browser to process.
