Frequently Asked Questions

Does WebP really make my website faster?
Yes! By switching from JPG to WebP, you can reduce your page weight by several megabytes, which leads to faster loading times and better rankings on Google.
Is it safe to convert my business photos here?
Absolutely. At imgDuo, we are software engineers who prioritize security. We built this tool to work entirely client-side, meaning your business assets are never uploaded to our servers.
Will the WebP image look the same as my JPG?
Yes. WebP is designed to provide high-quality visual output at a much lower file size. Most users cannot see any difference between the two formats.
