How Our Privacy Engine Works
When you drop an image onto VisualConvert, our code runs entirely inside your device's web browser using modern web standards (Canvas API & WebAssembly). Unlike traditional converters that upload your photos to remote servers, process them there, and send them back, VisualConvert processes everything locally in your computer's memory. You can verify this anytime: open your browser's Developer Tools (F12), switch to the Network tab, and drop a file — you will see zero upload requests!
About converting PNG to WebP
Ask any front-end developer where the easy performance wins hide and they will point at the images. Unoptimised PNGs are often the single heaviest thing on a page, and heavy images are what drag down Largest Contentful Paint — the Core Web Vitals metric Google watches when it decides how to rank you. Re-encoding those PNGs as WebP typically trims 25–35% off each file for the same visible result.
For an e-commerce catalogue that difference compounds across hundreds of product shots: lighter thumbnails, faster category pages, a better PageSpeed number, and a measurably quicker experience on the mobile connections most shoppers use. As of 2026 WebP is supported by every current browser, so there is no fallback tax for making it your default.

PNG to WebP — Frequently Asked Questions
How much smaller will my PNGs get as WebP?
Expect roughly 25–35% smaller for the same visible quality, and often more for detailed graphics. Across a full page or catalogue that adds up to a noticeably faster load.
Does converting PNG to WebP actually help Core Web Vitals?
Yes. Image weight is a primary driver of Largest Contentful Paint, so lighter WebP hero and product images improve that score and, in turn, your PageSpeed and ranking signals.
Is WebP safe to use as my default in 2026?
It is. Every current browser renders WebP natively, so you can ship it as the default image format without maintaining a PNG fallback for compatibility.
