Update 27.08.2020 - Windows 10 Edge and Firefox are no longer supported
Because of the recent changes in Firefox, PDF conversion is no longer technically possible. Although we reached out to Mozilla, there will be likely any action. Thus, until the new changes are still active, Night Eye is unable to convert PDFs. You can still use Chrome and Chromium based browsers to enable smooth dark mode on online PDFs.
The recent changes by Microsoft limit our ability to convert PDFs and enable dark mode for them. Sadly there is no workaround and might never be, unless Microsoft lift the limitations. Night Eye enables Dark mode for PDFs on all other browsers and you can still enjoy reading them without hurting your eyes. Check out the list of browsers that Night Eye is available for here
Reading PDFs at night can be a real pain. You're most likely familiar with the situation - it is late at night, you have to go through a pdf file that is 20-30 pages long and the bright background is simply not helping. Your eyes are already tired from spending you whole day in front of the monitor and now this...
If you are familiar with those circumstances, you probably have already searched for "reading pdf at night"
or "pdf dark mode"
. The results are pretty outdated - 2010 (Lifehacker) and 2016 (MakeUseOf) also not really useful as they require you to adjust some settings in Adobe Reader.
The good news is that there is a solution that requires minimum efforts from you and will offer good enough solution, that will help you fight eye strain when reading pdfs late at night.
