When Should You Convert PNG to JPG?
Converting PNG to JPG makes sense in specific situations where file size matters more than transparency or pixel-perfect precision:
- The image is a photograph and you do not need transparency — JPG is the right format for photos
- You are uploading to a platform that does not support PNG or has strict file size limits
- You need to send the image via email or messaging and a PNG screenshot is too large
- The PNG contains a white background (not transparent), making PNG's transparency advantage irrelevant
When NOT to Convert PNG to JPG
- The image needs transparency: JPG cannot store transparent pixels. Any transparent areas will be filled with white in the output JPG.
- The image has text, logos, or sharp lines: JPG compression introduces visible artifacts around hard edges and text. A logo or screenshot will look noticeably worse as JPG.
- You plan to edit and re-save the file: Each JPG save recompresses, degrading quality progressively. Keep working files as PNG.
How to Convert PNG to JPG on ILoveConvert
- Go to ILoveConvert Image Converter
- Upload your PNG image
- Select JPG as the output format
- Set quality to 85–90% for the best size-to-quality ratio
- Download your JPG
Choosing the Right Quality Setting
- 95–100%: Near-lossless. Minimal compression. Use only when maximum quality is required. File size barely smaller than PNG.
- 85–90%: Excellent quality, significant size reduction. Recommended for most photography.
- 75–80%: Good quality with aggressive compression. Fine for web thumbnails and social media.
- Below 70%: Visible compression artifacts. Only for situations where file size is critical and quality is secondary.
What Happens to Transparent Areas
PNG files may contain transparent pixels (alpha channel). When converting to JPG, transparent pixels are filled with a solid colour — white by default. If your PNG has a non-white background that you want to preserve underneath where transparency was, you need to composite the image before converting.
File Size Difference to Expect
For photographic PNG images, converting to JPG at 85% quality typically reduces file size by 60–80%. A 3 MB PNG photograph often becomes a 400–700 KB JPG. For PNG graphics with flat colours and transparency (logos, icons), the file size reduction is smaller and the quality trade-off is less favourable.
