PNG to JPG: How to Convert Images Online for Free

Need to convert PNG images to JPG? Here's the fastest way — plus when you should and shouldn't convert.

Why Convert PNG to JPG?

PNG files are often 5-10x larger than JPG files with the same visual content. Converting makes sense when:

  • Uploading to websites that require JPG format
  • Sending via email where file size matters
  • Saving storage space on your device
  • Social media — most platforms prefer JPG

When NOT to Convert

Keep your PNG if:

  • The image has transparency (JPG doesn't support transparency)
  • It's a logo or icon with sharp edges (JPG adds artifacts)
  • It's a screenshot with text (JPG blurs text)
  • You need to edit it again later (lossy compression degrades with each save)

How to Convert PNG to JPG

Using Snelfo Image Compressor

1. Go to Snelfo Image Compressor 2. Upload your PNG — drag and drop 3. Set quality to 85% — this preserves most detail 4. The output will be JPG automatically 5. Download

Using Paint (Windows)

1. Open the PNG in Paint 2. File → Save As → JPEG 3. Choose quality and save

Using Preview (Mac)

1. Open PNG in Preview 2. File → Export 3. Choose JPEG as format 4. Adjust quality slider 5. Save

File Size Comparison

We tested with a typical screenshot (1920×1080):

FormatFile SizeNotes
|--------|-----------|-------|
PNG (original)2.8 MBLossless, perfect quality
JPG (95%)320 KBVirtually identical
JPG (85%)180 KBGreat quality, much smaller
JPG (70%)120 KBGood quality for web
WebP (85%)140 KBBest option for web

Pro Tips

1. Always keep the original PNG — in case you need to re-edit later 2. Use WebP for web — 25-35% smaller than JPG at the same quality 3. Batch convert — if you have many PNGs, convert them all at once 4. Check the output — zoom in to 100% and verify text is still readable
