How the JPG to PNG Converter Works
Your JPG is decoded and re-encoded as PNG entirely in your browser. The image is drawn to a canvas and exported with canvas.toDataURL('image/png') — no server upload, no waiting.
This keeps your photos private and makes conversion instant and offline-capable. Because PNG is lossless, every pixel is preserved at full quality.
Why Convert JPG to PNG?
- Lossless quality: PNG uses DEFLATE compression with zero visual loss — ideal for editing, printing, and archiving.
- Ready for transparency: After conversion you can edit the PNG in any editor and add transparent backgrounds (JPG itself never has transparency).
- Sharp edges: PNG avoids JPG block artifacts around text and lines — great for graphics and screenshots.
- Universal support: PNG is supported everywhere — browsers, phones, design tools.
Frequently Asked Questions
Will my JPG become transparent?
JPG has no transparency, so the converted PNG will have an opaque background matching the original. You can later edit the PNG to make areas transparent.
Is the file size larger after JPG → PNG?
Often yes. JPG is lossy and highly compressed; PNG is lossless, so the same photo at full fidelity can be larger. Use PNG when quality matters, JPG when you need smallest size.
Is this private and offline?
Yes. Files never leave your device, no upload, works offline after page load. No signup required.
Can I convert multiple JPGs at once?
Yes — drop many JPGs, convert in one click, then download individually or use “Download All PNGs”.
