Download pdfs to kindle7/8/2023 When deciding for the 'next' reader/tablet to buy my biggest concern along with cost/weight/resolution was ease of reading PDFs especially in portrait mode. Single column PDFs with lots of text read fine, but you may have to change orientation of the device to see what fits best. It'll be very jerky and quite irritiating. E-inks are horrible for that since they don't redraw the screen continuously. If the screen is small, you have to pan/zoom. The PDF in essence shows up as the size of the screen on which it's displayed. So, this makes it all the more difficult on e-ink screens since they don't really have a screen refresh rate (e.g. Regenerating the original word file (say) requires complex AI algorithms and the like and is not 100% correct, unless the conversion itself was of a simple document with headers/text only. In fact, generating a PDF is quite algorithmic in nature. Tools exist but do a miserable job at it. You just can't wrap the lines at a screen boundary. Hence the need to zoom/pan when reading PDFs. When PDF was designed they never envisioned screen size to shrink to that of an iPhone. That is the text is printed at certain xy coordinates on the paper (gross simplification). PDFs are what are known as non-reflowable formats. I'm sure a LOT of folks have the same issue. It will also often lead to page numbers or chapter names (if it is written on top of every page) in between the text. This will usually fail completely in multicolumn documents, will remove images and destroy mathematical formulas. I used it for text books as well for years, so it is not too annoying.Īnother option is converting the PDF to Mobi using Calibre or Amazon's mailing service. if you have large tables in your document. It is fine for texts you read without going back and it's still the way to go e.g. This can be quite annoying with multicolumn documents or if you want to go back just one page to look something up (may feel slow). Other than this you can of course read in landscape mode. They are KOReader (for Kobos, Pocketbooks, reMarkable and Kindles with a touch screens), KindlePDFViewer (for Kindles with keyboard) and Librerator (for Kindles with neither touch nor keyboard).Ī clear disadvantage is that these programs seem to drain more battery than the official PDF viewer, but on the other hand reading is more convenient, because you can still read in portrait mode and your pages are preprocessed in the background (turning pages feels faster in large PDFs with many images). The readers are all forked from the same project and only differ in how you input your data. These also have the advantage that you can use the PDF's table of contents (something the official PDF viewer does not support). If you do not mind jailbreaking your reader, there are also PDF viewers that include k2pdfopt and so you can change font size and other parameters on the fly. The conversion progress is largely automatic, just give it a try. Text reflow preserves images and even mathematical formulas - which is something that Sony's built-in text reflow cannot do.ĭownload the program, set the options for your reader on a Windows/Mac/Linux machine and generate a new PDF with only one column, cropped margins and possibly larger letters. Newer versions of the program can even text. It can handle up to four columns, works with "normal" (using actual stings in the PDF) as well as scanned text and will turn your input PDF into a PDF with more pages optimized for your screen's size. You can use the free tool k2pdfopt to optimize PDFs for your reader's display size. It is possible, but will need prior processing for optimal results.
