Format guidance
When does JPG to PNG make sense?
PNG is widely used for graphics workflows and supports transparency, but converting an existing JPG does not recreate transparent areas or recover detail lost during the original JPG compression.
A PNG made from a photograph is often larger than the source JPG. Convert when the destination format or workflow needs PNG, rather than expecting an automatic reduction in file size.

Practical conversion tips
No quality slider is needed
PNG output is lossless, so the converter hides lossy encoder quality controls.
Expect possible growth
Complex JPG photographs often produce larger PNG files; the real difference is shown after conversion.

Frequently asked questions
Can I convert JPEG to PNG too?
Yes. JPEG and JPG are two common extensions for the same image format, and both are accepted.
Will converting JPG to PNG improve quality?
No. PNG avoids further lossy encoding, but it cannot restore detail that was already removed from the JPG.
Will the new PNG have transparency?
No. Existing JPG pixels remain opaque because JPG does not contain transparency information.
Is the JPG uploaded?
No. The JPG is validated and converted locally in your browser.
