The weight of my epub is too high (14 mo). What can I do to reduce this weight ?

What is this epub? Is it one you made? One you bought? DRM? Does it contain a lot of images? A lot of text? Embedded fonts?

I did this ePUB with SIGIL. This is the file : http://manuscritdepot.com/doc-transf...yn-malo.1.epub (this file is copyrighted by my and the authour - I'M a publischer)

Remove all those fonts, you aren't using any of them.

One of them alone is 22MB.

That will drop the book down to 1.2MB instead of 17MB which should help tremendously.

EDIT: That might be because, as DomesticExtremis points out below, nofew styles are in use... only the auto-generated styles for the ToC are in use.

Still, do you really need to embed arial specifically? Embedded fonts are something IMO to be used as a last resort.

Apart from the TOC.xhtml, none of your xhtml files is using any style
sheet, so it will be defaulting to whatever your eReader or software is using.

There are lots of errors coming from FlightCrew (Tools|Validate... in sigil)

You might want to fix those first before worrying about font size.

Plus, the ePub isn't using them as they haven't been embedded properly.

The main error is the persistent use of style <* align="center"> instead of text-align, which isn't a tremendously difficult obstacle.

Yes I noticed, and edited my post appropriately.

Thank you very much.

I remove all fonts.

But the replacement of text-align doesnt work.

As you know, I use :

<h2 style="text-align: center;">Préambule</h2>

What should I use ?

eschwartz · 02-25-2015, 04:06 PM

You will still want to actually link the stylesheet (right-click on files in the file browser baked into Sigil) and you want to replace "align" with "text-align", not the other way around.

saguay · 02-25-2015, 04:10 PM

I decide to add text-align in the css. The problem is solve for the title (H2). But I still have the same problem with <p align="center">* * *</p>

It's done. Thank you.

On the ePub check IDPF, they wrote : attribute "align" not allowed here; expected attribute "class", "dir", "id", "lang", "style", "title" or "xml:lang"

I dont understand

PeterT · 02-25-2015, 05:08 PM

While yes, you can code

Code:

<p style="text-align:center">* * *</p>

it's being suggested that using a stylesheet and named styles would be more beneficial.

You would want to make a new stylesheet (say my.css) and it would contain

Code:

.center {
    text-align: center;
}

Then you would link my.css to the files within the eBook within Sigil, and in the actual files just code

Code:

<p class="center">* * *</p>
<h2 class="center">Préambule</h2>

Or if you wanted ALL <h2>'s to be centered you could place in my.css

Code:

h2 {
    text-align: center;
}

and then just code

Code:

<h2>Préambule</h2>

You also might like to look at some of the resources here at MobileRead on eBook creation.

For instance https://wiki.mobileread.com/wiki/EPub_Tutorial which deals with CSS and stylesheets among other topics.
