You can find an excellent website for downloading free public domain SVG files at FreeSVG.org. As of this writing, they have more than 165 thousand SVG designs published.
Free Public Domain SVG Images, SVG Cut Files, and Transparent PNG
The website has simple navigation options starting with a search box.
All of the images have multiple tags so that Tag Clouds are on each of the pages. They've done an excellent job defining these tags so that related tags display for each image.
Popular SVG vector tags include War, Peace, Cricut SVG, Ukraine, and Love. In addition, there is a wide variety of public domain SVG files to be found on this website.
SVG files are free to download with registering. However, the PNG format images require you to register an account and log in before allowing the free download.
Cute Bird Public Domain SVG Image
The first SVG image I decided to download is called a Cute Bird Image. The actual file name is Ptarmigan.
The SVG file is easy to download - a big, green button says Download SVG. However, as mentioned earlier, the PNG format download requires you to create a free account and log in.
Once I downloaded the SVG file, I created a new file in Vectric Aspire. Then, I imported the vector file and resized and centered the design to fit the material.
There are a LOT of vectors in this design!
The first vector check is to enable the node editor. While there are a ton of node points in this image, there are also many smooth blue-colored nodes. It's a good sign when you see this many blue nodes instead of them being all black, short straight nodes.
The Vector Validator offered another big surprise. With all these vectors, it only found twenty-four vector intersections. I was expecting a lot more issues than this.
The final vector quality check used the software to find any "open" or "duplicate" vectors. The software did find one or more of the "open" vectors, but they were so small I could not find them. Likewise, the search did not find any "duplicate" vectors.
The last task was to create a V-Carve tool path to see how well the design carves in the software simulator.
I used the 60-degree v-bit without any clearance tools. I also disabled the Flat Depth option. However, the tool path did calculate with an error message warning of the vector problems.
I ran the tool path using the software simulator, and the result was excellent. This image is one of the most detailed vector designs I've downloaded for free, and I had it carved right the first time.
Rose By Rani26 Public Domain SVG Image
The second vector image I downloaded was called a Rose By Rani26. It was a simple yet detailed design with jagged-edged leaves.
I downloaded the image vector file as quickly as the cute bird image. Once saved on my PC, I created a new file in Vectric Aspire and imported the vectors. Next, it needed to be resized and centered on the material.
Surprisingly this design was perfect for a V-Carve tool path, having two sets of vectors for the borders.
The first vector quality check was to enable the node editor. The vectors looked clean, with a more significant concentration of black-colored nodes around the leaves. But the leaves had jagged edges, so the design required a higher number of straight black nodes.
There were more blue-colored smooth nodes on the rose petals, which were more curved in design.
The vector validator did not find any problems with the design. Perfect vectors.
The software did not find any "open" or "duplicate" vectors either.
The final step was to create a V-Carve tool path. I used my 60-degree v-bit once again without a clearance tool. I also disabled the Flat Depth option.
The software calculated the tool path without any vector error messages.
I ran the tool path using the software simulator. The result again looked excellent. It's a perfect design with a good amount of detail. All of this is for free.

You must verify all tool path settings, especially the bit settings, to ensure they are compatible with your CNC machine. Every CNC machine operates differently!
