Frequently Asked Questions (FAQs)

What is the difference between PNG and JPG?

PNG is a lossless image format that supports alpha transparency channels and keeps details sharp, making it ideal for text and logos. JPG is a lossy format that compresses files to much smaller sizes, best for digital photographs.

Does converting a JPG to PNG make the image quality better?

No. Converting a JPG to PNG keeps the quality exactly as the original JPG, but prevents further quality loss from edits. It cannot recreate details that were already lost in the original JPG.

Why is my PNG file size larger than the original JPG?

PNG uses lossless compression to preserve every pixel, resulting in much larger file sizes compared to lossy JPG compression.

Does this converter support transparent backgrounds?

Yes. If your source image (such as WEBP) contains transparency, the converter preserves the transparent background channels in the exported PNG.

Is it safe to convert my images on this site?

Yes, absolutely. The conversion code runs locally using client-side JavaScript. Your images are never uploaded to our servers, keeping them private.

Can I convert PNG files on a mobile phone?

Yes, our converter is fully responsive and runs on any smartphone browser.

Can I convert PDF pages to PNG?

Yes. You can convert PDF pages to PNG using our PDF to JPG/PNG converters to save pages as images.

Is registration required to use the PNG converter?

No, all conversion tools on our site are completely free with no signup requirements.

How do I reduce PNG file size without losing quality?

You can run the PNG through image compressors or export it as an optimized 8-bit PNG, though this may reduce the color depth.

What software do I need to open a PNG file?

PNG is a universally supported web format that opens natively on all web browsers, photo viewers, and operating systems.
