My free EPUB tools, without any ads or tracker | Epublys.com
Epublys — what changed since I last posted it here
Quick reminder of what it is: Epublys is a free EPUB toolkit that runs in your browser. You can merge, split, compress, convert to and from PDF, edit metadata, validate and read your books, with no install and no account for the core tools. Files are processed in memory and never stored anywhere.
I've put a lot of work into it since the first post, so here is where it stands now:
You can read both EPUB and PDF directly in the browser, with a real table of contents, search and bookmarks. It now keeps your theme and font size from one book to the next. Sounds small, but I missed it myself.
The validator doesn't only tell you what's wrong, it fixes the most common problems in one click. If you publish on Amazon KDP or Apple Books, run your file through it first, it catches the structural things that usually get books rejected.
Converting between EPUB and PDF gives you clean files with no watermarks.
There is an AI cover generator if you need a cover. You describe the book, it generates one, and you apply it to your EPUB without leaving the page. This one is part of the paid tier, which you don't need to use but I'll appreciate support to keep this ads free forever.
You can process a whole batch of files at once and download everything as a single ZIP.
It's faster than before and works properly on mobile.
And a lot of smaller things across every tool that I won't list one by one.
About the paid side: if you want to support the tool, feel free to subscribe. If you don't, that's completely fine too. We still managed to deliver more than 2,000 EPUB operations over the last 3 months, and the free tools are not going anywhere.
The thing I'd genuinely like to know is this: what is the EPUB problem you keep running into that no tool handles well? That's what I want to build next.
