PNG to JPEG Converter
Converts PNG images to JPEG format. Dramatically reduces file size for photographs stored as PNG. JPEG compression can reduce a 5MB PNG photo to under 500KB.
What is it used for?
- Reducing photo file sizes that were saved as PNG
- Preparing images for web upload with size limits
- Converting screenshots for sharing (when transparency isn't needed)
- Batch image optimization
Step-by-Step Guide
- Upload a PNG image
- Adjust quality (1-100)
- Click 'Convert to .JPG'
- Download the JPEG
How it works
Upload a PNG image, adjust quality, and click Convert. wasm-vips converts the lossless PNG to lossy JPEG.
Tips & Best Practices
- Quality 85 is excellent for photos
- Transparency will be replaced with white
- Consider WebP for even better compression
Frequently Asked Questions
How much smaller will the JPEG be?
For photographs, JPEG is typically 5-10x smaller than PNG at quality 85. For graphics with flat colors, the savings are less dramatic.
Privacy & Security
This tool uses wasm-vips (libvips compiled to WebAssembly). The WASM binary (~5MB) is downloaded on first use and cached by your browser. All image processing happens locally on your device - your images are never uploaded to any server. This makes it safe for sensitive, private, or confidential images.
