This image has transparency — JPEG doesn't support it, so transparent areas will be filled with white.
Frequently asked questions
Why do exam portals require JPEG format specifically?
JPEG is the most universally supported image format with predictable, controllable file sizes, which is why most government exam application portals only accept JPEG or JPG uploads, rejecting PNG, WEBP, or other formats.
What JPEG quality should I use for exam photos?
A quality setting between 70 and 90 percent is usually sufficient for passport-style photos, balancing clear detail with a manageable file size for upload limits.
Can I convert a PNG or WEBP photo to JPEG here?
Yes, this tool accepts any common image format and converts it to JPEG, filling any transparent areas with white since JPEG does not support transparency.
I need an exact KB limit, not just a quality percentage — what should I use?
This tool gives direct control over quality percentage. If you need to hit a precise KB target like 50KB automatically, use the Image Compressor tool instead.
