JPG to PNG tips

🎨

PNG is lossless — every pixel is preserved exactly. Great for screenshots, logos, and graphics with text or sharp edges.

🔍

PNG supports transparency (alpha channel). JPG does not — if you need transparent backgrounds, PNG is the right choice.

📏

PNG files are typically 5–10× larger than JPG for photos. Only convert to PNG when you need the quality or transparency.

💡

Converting JPG → PNG doesn't restore lost quality — JPG artefacts from the original compression remain visible.

Dewiswch Ffeil

Drop your file into the tool above. It stays entirely on your device — nothing is sent to any server.

Proses

The JPG to PNG preset (quality 100%) is applied automatically. Adjust any setting you like.
