How to Convert PNG to JPG Online
Convert PNG to lossy JPG in your browser. Compare file size and quality, and understand transparency changes before sharing.
For some photos, converting PNG to JPG reduces file size. The result depends on content, dimensions and encoder settings; a smaller file or invisible quality change is not guaranteed.
How to Convert PNG to JPG Online
- Go to the PNG to JPG converter on this site.
- Click Choose Files and select your PNG image(s). Batch conversion is supported.
- Adjust the quality slider if needed (default 92), then inspect the output.
- Click Convert and download your JPG file(s).
Everything runs in your browser — your files are not uploaded to a server.
When Should You Convert PNG to JPG?
Convert PNG to JPG when:
- Your image is a photograph or a complex photo-like image
- You need to reduce file size for email or web upload
- The platform you're uploading to requires JPG
- You don't need a transparent background
Keep the PNG when:
- Your image has a transparent background (JPG doesn't support transparency — it will be replaced with white)
- The image contains sharp text, logos, or line art (JPG compression creates visible artifacts on hard edges)
- You need pixel-perfect accuracy
How Much Smaller Does JPG Get?
There is no fixed reduction. Compare the input and downloaded sizes using the same pixel dimensions. Also check text, edges and gradients; a small output is useful only if it meets your quality needs. Flat-color graphics may already compress efficiently as PNG.
Things to Know Before Converting
Transparency will be lost. If your PNG has transparent areas, they'll become white in the JPG. If you need transparency, consider converting to WebP instead with the PNG to WebP converter.
JPG is lossy. Each time you save a JPG, the quality degrades slightly. If you plan to edit the image further, keep the PNG as your working file and only convert to JPG for the final output.
Other Ways to Convert PNG to JPG
On Mac
Open the PNG in Preview → File → Export → select JPEG and adjust the quality slider.
On Windows
Open the PNG in the Photos app → three-dot menu → Save a copy → choose JPEG.
In Photoshop
File → Export → Export As → select JPG and set the quality.
Frequently Asked Questions
Will converting PNG to JPG reduce the image resolution? No — the pixel dimensions stay the same. Only the file encoding changes.
Can I convert multiple PNG files at once? Yes — select multiple files when uploading to convert them all in one batch.
My PNG is a screenshot with text — should I convert to JPG? Generally no. JPG compression blurs fine text and sharp edges. Keep screenshots as PNG, or use WebP if you need a smaller file that still looks sharp.
