JPG to PNG Conversion
Converting a JPG to PNG makes it lossless, so any further edits won't introduce new compression artefacts — but the file typically grows 5–10x larger, since PNG can't match JPEG's compression on photographic detail. Conversion runs entirely in your browser, so nothing is uploaded.
JPG vs. PNG
| Format | Best for | Compression | Transparency |
|---|---|---|---|
| JPG | Photos | Lossy | No |
| PNG | Graphics, screenshots, logos | Lossless | Yes |
Converting doesn't restore detail a JPEG already lost — it just stops further loss. For a smaller file that still beats plain JPEG, try converting to WebP instead.
Frequently asked questions
Why convert JPG to PNG?
PNG is lossless, so it avoids further quality loss during editing and supports transparency, which JPEG cannot.
Will the PNG look better than the JPG?
No — converting can’t restore detail already lost to JPEG compression. It just stops any further loss from happening.
Will the file get bigger?
Usually yes. PNG is lossless, so photographic images become larger than the JPEG original.
Is it private?
Yes — conversion runs entirely in your browser with no uploads.
How much bigger will the PNG be than the JPG?
Often 5–10x larger for photos. PNG’s lossless compression can’t exploit the redundancy in photographic detail the way JPEG’s lossy compression does.
Should I convert a JPG screenshot to PNG?
Converting won’t undo JPEG artefacts already baked into the pixels — for sharp text and UI edges, capture future screenshots directly as PNG instead.
Can I convert JPG to PNG and keep the file small?
Not really. PNG’s lossless nature means it can’t match JPEG on size. If size matters more than further editing, keep the JPEG or convert to WebP instead.
When should I use PNG instead of JPG?
PNG suits graphics, logos, screenshots, and anything needing transparency. JPG remains the better choice for photographs, where its lossy compression gives a much smaller file at a visually similar quality.
