How to Convert PNG to JPG
PNG files are great for screenshots, graphics, and images with transparency, but they're often much larger than necessary for photographs and general-purpose images. Converting PNG to JPG can shrink your file sizes by 60-80% with minimal visible quality loss — perfect for email attachments, website uploads, and storage-constrained situations. imageconvert.co handles the conversion locally in your browser, so your images stay completely private.
PNG vs JPG: What's the Difference?
| Feature | PNG | JPG |
|---|---|---|
| Compression | Lossless — every pixel preserved exactly | Lossy — discards data humans can't easily see |
| File size | Large (especially for photos) | Much smaller — typically 60-80% reduction |
| Transparency | Full alpha channel support | No transparency (transparent areas become white) |
| Color depth | Up to 48-bit (16-bit per channel) | 24-bit (8-bit per channel) |
| Best use case | Screenshots, logos, graphics with sharp edges | Photos, social media, email attachments |

Frequently Asked Questions
What happens to transparency when converting PNG to JPG?
JPG doesn't support transparency. Any transparent areas in your PNG will be filled with a white background in the resulting JPG. If you need to preserve transparency, consider converting to WebP instead, which supports both transparency and small file sizes.
How much smaller will my JPG files be?
It depends on the image content. Photos typically see a 60-80% reduction in file size. Screenshots with lots of text and solid colors see less dramatic savings because PNG is already efficient at compressing that type of content. The size comparison is shown for each converted file.
What quality setting should I use?
The default 92% works well for most photos — the compression artifacts are virtually invisible. For screenshots or images with sharp text, use 95-100% to avoid blurring around edges. For images where file size matters more than perfect quality (like thumbnails), 80-85% delivers significant savings.
Does converting PNG to JPG lose quality?
Yes — JPG is a lossy format, so some image data is permanently discarded during conversion. This is the trade-off for the dramatic file size reduction. At high quality settings (90%+), the loss is imperceptible for photographs. The original PNG file is never modified.
Can I convert PNG to JPG in bulk?
Absolutely. Drop as many PNG files as you want — they convert in parallel using Web Workers, and you can download them all as a single ZIP file when complete.
