Frequently Asked Questions

Q: What happens to PNG transparency when converted to JPG?

Because the JPG image standard does not support transparent alpha channels, transparent pixels are automatically replaced with a clean background color. You can choose white, black, or any custom color using our background picker above.

Q: Will converting PNG to JPG degrade image quality?

Our engine uses high-grade bi-cubic interpolation and allows you to adjust the JPG quality from 10% to 100%. At the default 92% setting, visual quality is virtually indistinguishable from the original PNG while drastically reducing file size.

Q: Is it secure to convert sensitive PNG files here?

Yes, 100%! NeedConvert uses in-browser HTML5 Canvas processing. Your files are never uploaded to any remote server or third party cloud storage.

Q: Can I batch convert multiple PNG images at once?

Yes, you can upload dozens of PNG images simultaneously and download all converted JPGs in a single organized ZIP archive.

Q: Is there any file size or usage limit?

No, NeedConvert is 100% free with unlimited conversions and zero artificial file size caps.
