Last week I was experimenting with Mobipocket Creator for better conversion results and better styling from PDF to PRC, I found out that if you crop out page numbers and headers before converting it with mobipocket creator, you will get better accuracy and better styling.
Also, I would like note, mobipocket creator has problem of removing page number with
roman numerals. By cropping you will make sure, that issue is also resolved.
For cropping pdfs, there is a simple and free software called
Briss to crop pdf files. Portable version is also available. [
Watch screencast on how to use it.]
1. Run Briss
2. Load the file
3. Cancel the warning, if you don't know what to do.
4. On the cropping screen, all the odd pages will be superimposed into a singe look, so do the even pages, and blue rectangle with small dark squares at the corners will appear on each pages. Drag these squares to set the margins of the cropping for better result. You can preview it by clicking action on the menu bar >> Preview
5. Once you set the margins, click action >> Crop PDF
Briss is not stable enough, sometimes gives error and may not let you crop but, from my experience, you can always preview it. So if you can't crop directly, just preview and save as preview file.
