At first, I tried different online services, but quickly realized that with large or multi-page PDF files, the quality often suffers, and the files can take a long time to load. After that, I turned my attention to desktop programs, and this turned out to be a much more convenient option. I especially liked one tool that allows you to convert PDF to PNG while preserving all the details and colors, while you can adjust the resolution to your needs. For multi-page documents, it creates separate PNGs for each page without losing quality and does not create excessively large files. Another convenient thing is that the program supports batch processing, which saves a lot of time if there are several such documents. I was pleasantly surprised by the speed and stability of the work – no freezes or crashes, even with complex graphics.
