I tried various online services, downloaded programs to my computer, and even tried using commands in the terminal, but either the image quality left much to be desired, or the files were too large and inconvenient to work with. Fortunately, thanks to you, I finally found a really simple and effective way. The method turned out to be intuitive, with the ability to preserve all the details of the original document and at the same time control the size of the final image. I was able to convert several PDF files at once without losing quality, which significantly saved time and nerves. Now I feel much more confident in working with graphics and documents, and I can safely recommend this approach to anyone who faces a similar task.
