I built a small tool to make PDFs easier to read at night

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.

After doing that too many times, I thought:

Why can’t I just read the PDF text like an article?

So I built a small free tool:

I built it for my own night reading, but I’d love to hear feedback from anyone who reads PDFs on mobile.

Also, if you ever need to convert a dark PDF back to a light version, I made a related tool for that too:
