Frequently Asked Questions
Why should I convert PNG images to JPG for my website?
PNG is a lossless format designed for graphics with transparency, often resulting in large file sizes (e.g. 3-8 MB per photo). Converting photographic PNGs to JPG reduces file sizes by 70-85% without noticeable loss of visual quality, drastically speeding up web page loading and improving Google Core Web Vitals (LCP).
What happens to the transparent background in a PNG when converting to JPG?
Because the JPEG standard does not support an alpha transparency channel, transparent pixels are composited onto a solid background color. The converter defaults to a clean white background, but you can select black or any custom hex color.
Does converting PNG to JPG affect image dimensions?
No. The output JPG retains the exact native width and height of the original PNG image unless you choose to resize it.
Is there any limit to the number of PNG files I can convert?
No. The in-browser client-side engine allows you to process multiple images in batch mode without server quotas or queues.
