How to convert images to SVG?

Question

Image processing

There are many PNG and JPG images on the site.
How to properly convert these pictures into SVG so that they are less fun and without losing quality? As I understand it, a regular online converter is not enough?

Answer 1

In theory, no way. These are different entities. SVG - Scalable Vector Graphics. Those. Vector graphics. And you have JPG and PNG, which are raster graphics.
Technically, you can insert a raster into an svg file, but in practice this will not reduce the "weight" of the pictures.

Answer 2

It will be optimal to use the Webp format, which is what Google requires for optimization. The weight is much lower, there is practically no loss in quality.

Answer 3

See what pictures. There are such graphics on the site, which can really save the "weight" of the file in several orders of magnitude in svg. For example, large backgrounds, especially abstract ones.
But it also happens the other way around, when, oddly enough, the optimized png can be smaller than svg - there are svg in which there are a huge number of dots and there is no way to reduce it.
From experience, for example, a small logo 100-200px wide can be larger in svg than a png of the same size if it has significant font elements.
The argument "to weigh less" most often is not the most important when choosing a graphics format. The expediency of this or that format is determined by specific conditions.

Answer 4

If there is no designer and the question is fundamental, then you can increase your skill and learn how to tolerably convert a raster to a vector yourself:

• Install a graphic editor containing a raster tracer, for example AdobeIllustrator, CorelDraw (it is easier to trace). There are independent tracers, I won’t say the names)
  
• Master the tracing operation in it (there is a minimum of settings), put the tracing on the stream.
  
• Profit
  

I trace almost any raster on the machine in a couple of minutes. It's not about illustrations "rich" in color and characters, but about ClipArt style graphics. Sometimes you have to tinker with export, but all the logos, icons, etc. graphics are done with a bang and quickly.
ps tested with a dozen online tracers .. either horror or greedy, like this vectorizer.io, it is more or less adequate in terms of results, but it is clogged with ads and xs maybe viruses, shitty commerce ))
