I read a lot of PDFs at night, especially on my phone.

And honestly, PDFs are not great for that.

Most of them still feel like digital paper: white background, fixed layout, and tiny text. Dark mode helps a bit, but many tools only change the page color.

The bigger problem for me was mobile reading.

When the text is too small, I have to pinch zoom, move the page left and right, zoom out again, then repeat the same thing on the next paragraph.
