Frequently Asked Questions
What happens to transparency?
JPG does not support transparency. Transparent areas are filled with your chosen background color (white or black).
Why is JPG smaller than PNG?
JPG uses lossy compression which produces much smaller files than PNG lossless compression. For photos, JPG is typically 5-10x smaller with minimal visible difference.
Is my image uploaded to a server?
No. Conversion runs entirely in your browser using the Canvas API. Your image never leaves your device.
Can I convert multiple PNGs to JPG at once?
Yes. Upload up to 20 PNG files and they will all be converted in one batch.
Can I convert PNG to JPG on my phone?
Yes. OneConvertly works in any modern mobile browser including Safari on iPhone and Chrome on Android. No app needed.
When should I keep PNG instead of converting to JPG?
Keep PNG for images that need transparency, pixel-perfect graphics like logos, or screenshots with sharp text. Use JPG for photographs and images where small quality loss is acceptable.
Is there a file size limit?
Individual PNG files up to 100MB are supported, with up to 20 files per batch.
