Thanks, @Billy Kerr!
I saw the posts on StackOverflow (first and second) and figured out I'll need to use potrace.
First, convert PNG files to BMP, because potrace can work only with BMP. It is possible to do using an online site, but it's easier and always free offline.
To process multiple files using potrace, a bash script is needed:
You can't actually "convert" PNGs to SVG. It's not possible. There's no one to one mapping of raster images directly to vector images.
However, you can certainly auto trace raster images to make vectors, but results may vary and depend a lot on the kind of image, and the quality of the original, and the settings used in vector software. Inkscape ...
You have already got a suggestion to make a PDF. Illustrator opens and edits PDFs, so at least it works. An unfortunate thing with PDFs is that there can be numerous clipping masks which must be released + deleted and groupings which must be ungrouped.
Another possibility is to save the presentation as *.emf (=Enhanced Windows Metafile). Each slide of a ...
In fact, Trace Bitmap also gives quite reasonable results if you adjust the settings a bit.
Most importantly, set it to "Single scan", because you only have two colors in the image. Multiple scans is only for detecting several color levels, and the results are usually far worse. Adjust the "Brightness threshold" for best appearance.
TBH, bitmap tracing is not a good way to recreate such images in Inkscape.
An easy and more effective method is to recreate it manually. Drop some guides over the original raster image, use snap to guides, then use the Bézier tool to redraw the lines on top, and change the strokes to the desired thickness. Then delete the raster image.
Example: original ...
The shown image is blurry and noisy. A part of the defects can be caused by Imgur image service, but anti-aliasing has given 1...2 pixels wide blurry zones to the edges which cannot be fixed with adjustments. 1...2 pixels are much as percents due the low resolution.
Automatic tracing attempts are quite useless. In addition only special CAD drawing style ...
Based on some of the responses, I have finally found the solution. I built my resume in PSD and then opened the file with Illustrator using the 'objects only' function. Then I saved the file (with no compression) to PDF at maximum and WOW.
Photoshop would save the PDF at maxmimum compression to about 2MB but the quality was not good at all. Text would have ...
ase and aco files are not images. They are application code of color definitions within Adobe applications.
There may be a way to convert them directly to images, but I think that may be unlikely since the ase/aco formats are proprietary.
There are some online tools to display the colors. Such as ...

I would save your presentation as a PDF. Your friend will be able to import the PDF page(s) into Illustrator and edit the slides.
Go to File -> Export and choose PDF as the file format.
When they import the PDF pages into Illustrator, they will want to select the page and release the clipping mask. This will make it easier to select objects.
After downloading and checking out some Procreate brushes (.brush files), these appear to be zip archive files. So if you change the file extension to zip, and open the zip, you should be able to extract the PNG images contained within it. I assume .brushset is also similar - just a zip archive.
If you can get the images out, then you can use them to create ...
ImageMagick's convert function is going to call Inkscape for SVG images, which doesn't know anything about relative unit measure (such as ex). Nonetheless, browsers are very good with those units. Meets svgexport, a Node.js module and command-line utility which is perfect for this job. I converted a few hundreds images in a matter of minutes.
