How It Works
2
Start the PNG to JPG conversion
Click Convert to JPG and wait for the browser to process your image. The converter fills any transparent areas with white because JPG does not support transparency. Processing runs in your browser and performance depends on your device and image size.
- Transparent areas are automatically filled with a white background
- All processing happens in your browser — nothing is uploaded to a server
- Results depend on the image format, browser, device, and file size
3
Download the JPG file if available
When processing succeeds, the JPG file downloads automatically. The file keeps the same name with a .jpg extension.
- Your original PNG file stays untouched on your device
- In most cases the JPG will be smaller than the original PNG
Common Use Cases
Email Attachments & Fast Messaging
Convert heavy PNG photos to compact JPG files to send images quickly without exceeding email attachment limits.
Website Performance & Page Speed
Convert non-transparent graphic banners and photos from PNG to JPG to reduce page weight and improve site load times.
Social Media & Marketplace Uploads
Prepare product photos and gallery uploads for platforms that enforce strict file size caps on image uploads.
Tips & Best Practices
JPG files are smaller but lose transparency
JPG does not support transparency. If your PNG has transparent areas, those areas will become white after conversion. Keep a PNG copy if you need transparency later.
File-size reduction depends on the image
Complex photos and graphics typically see significant size reduction when converted to JPG. Very small or already optimized images may not shrink as much.
Processing depends on your browser and device
Conversion runs in your browser using canvas technology. Very large images may take longer to process or may fail depending on your device memory and browser capabilities.

When to convert PNG to JPG
PNG files can be large, making them hard to share by email or upload to websites. Converting to JPG produces a smaller, widely compatible file that still looks great for photos and web use.
PNG vs JPG
PNG uses lossless compression and supports transparency — great for graphics and editing. JPG uses lossy compression — great for smaller files and broad compatibility. Most photos and web images work perfectly as JPGs.
How it works
- Upload a PNG image.
- The image is converted to JPG in your browser.
- Download your JPG file.
Frequently Asked Questions
How do I convert a PNG image to JPG online?
Upload your PNG image, click Convert to JPG, and your converted JPG file will be generated and downloaded immediately in your browser.
Why did my transparent PNG background turn white in the JPG?
The JPEG standard does not support alpha (transparency) channels. Transparent areas are automatically filled with a clean white background during conversion.
Does converting PNG to JPG always reduce file size?
In the vast majority of photographic and complex images, the JPG output is substantially smaller than the PNG due to JPEG compression algorithms.
Are my images uploaded to an external server?
No. The conversion runs 100% locally in your web browser using HTML5 Canvas. Your images never leave your device.
Can I restore transparency if I convert the JPG back to PNG later?
No. Once an image is saved as a JPG, the transparent areas are permanently flattened into white background pixels.
