JPG to PNG Converter
Convert JPG/JPEG — the universal photo format accepted by virtually every exam portal, form and printer — to PNG, batch, free, and entirely in your browser. Files are decoded and re-encoded on your device; nothing is uploaded.
Why convert JPG/JPEG to PNG
JPG/JPEG is the universal photo format accepted by virtually every exam portal, form and printer. Converting to PNG trades some of that advantage for near-universal compatibility — every exam portal, printer, Windows Photos app and older Android device opens PNG without issue.
Batch conversion
Select several files at once — each is converted independently and, if there's more than one, delivered as a ZIP.
How it works
Frequently asked questions
Does converting to PNG lose quality?
There's a small, usually invisible quality trade-off going from JPG/JPEG to a compressed format — it does not happen when converting to a lossless target.
Can I set an exact output file size?
Yes, for photo uses (exam forms etc.) switch to the <a href="compress-kb.html">Compress Image to KB</a> tool after converting, or use the exact-KB image tools directly.
Is the original file changed or deleted?
No, the original stays exactly as it was — the converted copy is a separate new download.
