What changes
JPG is smaller but has no transparency, so a transparent background turns white.

How PNG to JPG conversion works
Converting PNG to JPG reduces file size by applying JPEG lossy compression, trading a small amount of image quality for a significantly smaller output file. PNG uses lossless DEFLATE compression, which preserves every pixel exactly and makes PNG files considerably larger than JPEG equivalents, especially for photographs with complex colour gradients. JPEG compresses by grouping pixels into 8x8 blocks and discarding high-frequency detail that the human eye perceives least effectively. At a quality setting of 85-95%, the visual difference from the original PNG is imperceptible for most photographic content. However, images with sharp edges, text overlays, or flat colour regions will show visible JPEG artefacts (blockiness) at lower quality settings. Transparent pixels in PNG are flattened to a solid background colour (white by default) since the JPEG format does not support an alpha transparency channel.
Sources and specifications
Quality levels for PNG → JPG
| Level | File size | Speed |
|---|---|---|
| Low qualitySmallest file, basic quality | Very small | Very fast |
| Medium qualityRecommendedBalanced size and quality | Medium | Fast |
| High qualityLarger file, great quality | Large | Moderate |
| Maximum qualityLargest file, best possible quality | Very large | Slow |
Image Tip: For photos, Medium quality offers the best balance. For graphics with text or sharp edges, use High or Maximum quality to preserve clarity.
When to convert
What the JPG file is good for and why people convert to it.
- Smaller files for photosLossy compression drops detail the eye rarely misses
- Better web performanceFaster page loading times
- Optimizing images for websites and blogs
- Reducing email attachment sizes
Where your file goes
- It travels to our server over an encrypted HTTPS connection and is converted there.
- The JPG file comes back as a private link. It stops working after 24 hours on Free and 7 days on paid plans, and then the files are deleted.
- Want the file to stay on your device? Private Mode converts images right in the browser. Open Private Mode
