How It Works Technically

Conversion Process

1. File Reading: Browser reads PNG file locally using FileReader API

2. Canvas Processing: Image is drawn onto HTML5 Canvas element

3. Background Handling: White background replaces PNG transparency

4. Quality Application: Selected quality percentage applied to compression

5. Data URL Generation: Canvas exports image as JPG data URL

6. Download Creation: Data URL converted to downloadable file

Privacy & Security

• No Server Upload: Conversion happens entirely in your browser

• No Data Storage: Images are processed in memory, not saved

• No Tracking: No analytics or user tracking implemented

• Temporary Storage: Files exist only during active session

Troubleshooting Common Issues

Issue: “Please select a PNG image file”

Solution: Ensure your file:

1. Has .png extension

2. Is actually PNG format (not renamed JPEG)

3. Isn’t corrupted

Issue: Image looks different after conversion

Causes & Solutions:

1. Transparency Lost: PNG transparency converts to white background

   • This is normal – JPG doesn’t support transparency

2. Colors Appear Different: Adjust quality to 90-100% for minimal color shift

3. Image Looks Blurry: Increase quality slider above 70%

Issue: Large files won’t upload

Solutions:

1. Check browser memory limits (typically 1-4GB)

2. Resize extremely large PNGs before uploading

3. Try a different browser (Chrome, Firefox work best)

Issue: Download doesn’t start

Solutions:

1. Check browser download settings/popup blockers

2. Ensure storage permissions are granted

3. Try right-clicking preview image → “Save image as”

Best Practices

Optimal Quality Settings

• Web Graphics: 60-75% (good balance of quality/size)

• Photographs: 75-85% (preserves detail, reasonable size)

• Print Materials: 90-100% (maximum quality)

• Thumbnails: 40-60% (small file size)

File Size Reduction Tips

1. Start with 85% quality, reduce until acceptable

2. A 100KB PNG typically becomes:

   • 40KB at 85% quality

   • 20KB at 60% quality

   • 10KB at 40% quality

Batch Conversion Workaround

Since this tool processes one image at a time:

1. Convert first image and note optimal quality setting

2. Use same setting for similar images

3. Keep browser tab open for multiple conversions
