Though if you really want to, Adobe Professional does have built in OCR which could be used to extract the text. The next simplest case is text-based PDFs. Calibre handled the text better. Paragraphs were set off from each other with whitespace, headings were bold and also separated from paragraphs.
The Amazon conversion eliminated whitespace between paragraphs, as well as before and after headings. Calibre also forced all fonts to the same size. Amazon preserved relative font sizes. This might seem like an advantage, but this had the effect of pumping up the font size of the body text of most of the document! The overall effect was painfully unreadable.
Footnotes are a little problematic. They end up appearing as regular text, as if you read down the page and just kept going from the last line of body text into the footnotes, then continued reading at the top of the next page. I also converted a short but more complex PDF document with embedded images and tables. The images were mostly bar charts with some explanatory text. With regards to image display, Amazon did a better job. Or rather, the Amazon converter did what it was supposed to do.
Calibre did display the images, but as mirror images! Not very useful. Neither converter did a good job with tables. Both of them stacked the columns and printed the result as regular body text no borders or other formatting , one column after the other. Utterly unusable. The 9. In fit-to-screen mode, the Kindle will display the PDF at the maximum possible size while still showing one entire page. Considering that the Kindle PDF viewer automatically trims white space from the edges, many journal articles will display at full size.
If you happen to have journal articles or book chapters scanned as two-page spreads, it would be nice to read these in landscape format. Unfortunately in landscape mode the fit-to-screen viewing option changes to fit-to-width, with unhappy results. The PDF fills the horizontal width of the Kindle screen whether or not it fits vertically , requiring an additional page view to see the bottom of the page, and then an up-and-down to view the second page in the spread, as shown in these images of one two-page spread.
There are alternatives to reading PDFs, even though most academic journal articles are still only available in PDF format. I have downloaded and read a few articles this way, and it is excellent.
Restart the Office application. If you are scanning texts into Acrobat, it's good practice to take the following steps before sharing them so that the file size will be smaller and the document easier to download and print: 1.
On the File menu, click Options. On the Mail tab, click Stationery and Fonts 4th option from the top. On the Personal Stationery tab, under Replying or forwarding messages , click Font. On the Font tab, change the font options to what you want to use for future messages. How do I read a pdf on the Kindle DX? Score: What is a Kindle?

The documentation for conversions in Calibre specifically mentions that multi-column PDFs are not supported. It was the first Kindle to have a native PDF reader -- no conversion necessary. I have yet to see any program which can successfully convert multi-column PDFs to any other format.
This is no weakness of Calibre and I did not mean to imply that I saw it as a weakness. Have you ever tried to use cropping tools to split the columns and then parse the resulting PDF? I haven't but it could be a nice experiment.
Yes, you certainly can. What's a little annoying about this is that each PDF page is usually split into three Kindle-pages, where the third one contains little to no text.
Yes, it is quite annoying, but I've tried converting many e-books in doc and pdf format to mobi, and there were very many blank lines or lines with a few words, which was more annoying to me. Depends how the document is prepared line breaks etc.
Interesting question. I'm sure a LOT of folks have the same issue. PhD PhD 1 1 silver badge 2 2 bronze badges. There are 2 reasons for this: PDFs are formatted for a fixed width and height that usually exceeds the resolution of E-ink Kindle devices, including the Kindle DX.
E-ink readers work best when used with E-ink optimized fonts, which are generally not used in PDFs. Joe Golton Joe Golton 1 1 gold badge 8 8 silver badges 15 15 bronze badges. Community Bot 1.

As an alternative to that I have successfully rendered these files in high resolution by printing them to multi-page TIFF files then used OCR on those to generate convertable text. Anthon Anthon 7, 3 3 gold badges 20 20 silver badges 55 55 bronze badges.

This can only work if the PDF has an underling text layer, many PDFs are just pictures of documents, even if there is a text layer it is often hopelessly jumbled.
