pdf2htmlEX renders PDF files in HTML. It aims to provide an accurate rendering while being optimized for Web display. It is designed for scientific papers with complicated formulas and figures, so a precise rendering is the first concern, but general PDF files are also supported.
SlideShoQ is PDF presentation software that supports two-screen presentations: One screen shows the current slide fullscreen, i.e. what you want to show on the projector for the audience; the second screen is your computer, which shows the current, next, and previous slides, current time, and other useful information.
I, Librarian is a PDF manager or PDF organizer that allows individual researchers or a group of researchers to create an annotated collection of PDF articles. Users may build the virtual library collaboratively, thus sharing the workload of literature mining. It enables smart browsing and fast searching in reference data and PDF files, and includes an advanced tool for mining scientific literature from PubMed, PubMed Central, NASA ADS, arXiv, IEEE Xplore, and HighWire Press.
PdfMasher is a tool to convert PDF files containing text into a ready-for-ebook set of HTML files. Most ebook readers support PDF files natively, but it's often a real pain to read those documents because you can't control the font size of the document and have to resort to the zooming feature instead. Another drawback of PDFs on ebook readers is that annotations are not supported. Unlike other tools that convert PDFs to ebooks, PdfMasher does not try to guess the role of each piece of text in the PDF, and instead asks the user about the role of each piece of text, and does so in an efficient manner.
MALODOS helps you to scan, store, and easily retrieve all your personal documents. Its storage format is open and documented, so your document archive can remain accessible even without MALODOS. The documents themselves are stored as standard PDF files, while their metadata (such as title, tags, and description) are stored into a separate SQLite database in an open format. With MALODOS, you can also manage existing files in PDF, JPEG, TIFF, and other formats, so you can still use the documents that you've already scanned. You can connect to any external OCR program to give access to a fulltext search feature.
Whyteboard allows you to annotate PDF and PostScript documents and various image formats. You can draw with common tools such as a pen, rectangle, ellipse, text tool, etc. You can draw shapes, which can be moved, resized, recoloured, etc. Your drawing history is stored, allowing you to replay it. Tabbed painting is supported, with each sheet having its own unlimited undo and redo operations. There are live-updating thumbnails for each sheet. Sheets that are closed can also be undone, restoring their data. Note controls, similar to virtual, editable Post-It Notes. A draggable, live-updating resizable canvas that stretches to whatever size you want.
