What is the best format to convert images to for website speed and SEO?

WebP and AVIF offer superior compression compared to traditional JPG and PNG. Converting to WebP typically reduces image file sizes by 30–50% while preserving visual clarity and alpha transparency.

Will converting a PNG to JPG remove its transparent background?

Yes. The JPG/JPEG format does not support alpha transparency channels and fills transparent areas with a solid white background. To preserve transparency, choose PNG, WebP, or AVIF.

Select the PNG to ICO preset or choose ICO as your target format, drop your PNG or JPG logo, and click Convert. You can then download your converted .ico file ready to place in your website root.

Will converting a JPG to PNG improve its image quality?

Converting to PNG prevents future quality degradation during editing and re-saving, but cannot magically restore pixels already compressed or removed by the original JPEG encoding.

Does converting JPG to PNG make the background transparent?

No. Standard JPG files do not contain alpha transparency channels. To remove the background, use our AI Background Remover after converting.

Why is the output PNG file size larger than the input JPG?

PNG is a lossless format that stores every pixel value without discard compression, resulting in larger files than lossy JPEG.

Is there a limit on file dimensions or count?

No. ConvertnEdit allows unlimited conversions with zero file count or size caps.
