converted file 4 times larger than original

had to install Calibre on a replacement pc and suddenly all the conversions in 0.9.13 are 4 times bigger than the original.
this happens when converting to epub from epub,mobi or pdf.
i have ticked for no cover
have i missed another option somewhere?

update:
all versions from 0.9.04 to 0.9.17 enlarge the file size by a factor of 4

Try with a book you download from here, and specify the sizes. That way we can test as well.

Check the combined size of the four fonts you embed. Perhaps they are extra large versions of Arial with a lot of fancy unicode chars?

On my computer they are just shy of 1 mB combined uncompressed. And around 500 kB compressed.

Doing the conversion ePub -> ePub with embedded fonts resulted in 1.4 mB ePub. Just as expected.

When converting:

ePub -> mobi -> ePub without embedding the sizes were:
839.7 kB -> 912.0 kB -> 838.3 kB

So the file actually became smaller!

Calibre 0.9.17, Ubuntu 12.10, msttcorefonts.

The fonts are not emebedded. They are externally referenced. This is code for a Sony Reader (pre-T1). The OP is using a 505.

Up until 0.9.3 calibre didn't have the embed font family feature. That feature was new with calibre version 0.9.4.

Quote:
Release: 0.9.4 [26 Oct, 2012]

New Features
  • Conversion: Add an option to embed a font family into the book. The embedded font is used as the base font for all text that does not specify its own font family in the input document. Works only with output formats that support font embedding, principally EPUB/AZW3. Option is found under Look & Feel in the conversion dialog. You can ensure that the font is used for all text, regardless of the input document's styles by filtering out font family styles via the Filter Style Information option in the Conversion dialog.
The "make embed font family" step you have listed below can't be done as stated in any version before 0.9.4.

Clear out the Embed font family and follow everything you did in previous versions and your size will be back to where it was before.

The font is embedded after version 0.9.4 if you choose that option for conversion and the OP is choosing that option.
