About this conversion
Convert PNG to JPG to dramatically reduce file size. PNG is lossless and great for screenshots and graphics, but for photographs it's overkill — JPG can produce a visually identical result at 5–10× smaller file size. Ideal for web pages, email attachments, social uploads, and anywhere bandwidth matters.
When this conversion is useful
- Shrinking high-resolution photo PNGs before emailing or uploading
- Replacing photographic PNG assets on a website to improve page-load speed
- Trimming screenshot file size for sharing in messaging apps
- Preparing a batch of images for a service that has a strict file-size limit
Quality and tradeoffs
JPG uses lossy compression and doesn't support transparency. Any transparent regions in the PNG become solid white in the JPG output. For logos, icons, or images with see-through areas, stick with PNG or use WebP.
Frequently asked questions
How much smaller will my JPG be compared to the PNG?
Photos typically shrink by 70–90%. A 4 MB PNG photo often becomes a 400–800 KB JPG with no visible quality loss.
What happens to PNG transparency when I convert to JPG?
JPG doesn't support transparency. Transparent pixels are filled with white. If transparency matters, convert to WebP or keep PNG.
Will the JPG look worse than the original PNG?
On photographs, the difference is almost imperceptible at high quality settings. On flat graphics or text, JPG can introduce visible artefacts — for those, prefer PNG or WebP.
