Frequently Asked Questions
Why did my transparent background turn black or white?
The JPG format does not support alpha channel transparency. When converting from a transparent PNG, the browser's canvas renderer fills empty pixels with a default background color (usually white).
Is there a limit to the image size I can convert?
This tool processes images locally on your device. While there is no hard limit on OTechy's side, extremely high-resolution images (>50MB) may depend on your device's available RAM for the browser canvas.
Does converting PNG to JPG reduce image quality?
Yes. JPG uses "lossy" compression to reduce file size. However, setting the quality factor to 0.9 or higher makes the difference virtually indistinguishable to the human eye for most use cases.
Is this tool secure for sensitive documents?
Absolutely. Your files are processed entirely client-side. No data is sent to our servers, ensuring your images never leave your local environment.
How much smaller will the JPG be compared to the PNG?
Depending on the image complexity and your quality settings, you can expect a file size reduction of 60% to 90% compared to the original PNG.
