PDF Tricks for Researchers

PDF files are the best way to store, share and read your documents without disturbing the format of the original file. Being a researcher, you will encounter a lot of PDFs during your research span.

Whether it’s your résumé, research paper, a tax form, e-book, user guide or a web page, you can’t go wrong using a PDF. Chances are you’ve already got a free PDF reader installed on your computer, but you can do a lot more with your PDF files than you might think. Following are 10 best tricks that you can do with your PDF files.

Convert PDF to Word Online

PDF to Doc ConverterConverting PDF file to Word is necessary when you want to make certain changes in your PDF such as changing design, photos or text. I found it also useful in copying text or images from a PDF file. Adobe Acrobat premium can do this for but it cost you a paid subscription.

A PDF file can be converted into Word for free using a tool known as smallPDF. This tool has a limit of 2 conversions in an hour. If you want to do more than that, you can use another tool PDF to DOCX.

Speed Up PDF File

PDF can be very slow sometimes to open. This primarily occurs due to the too much multimedia content in your PDF or unnecessary add-ons in installed with your PDF Reader. There is a tool which makes Acrobat and Reader load faster by disabling plug-ins, updates, splash screens, and other startup slowdowns.

You can allow the plug-ins and features you want or enable them as you need them. You can download the tool from CNET.

Merge PDF Files Online

Sometimes you need to combine different book chapters or research papers in a single PDF. Merging those PDF files can help you a lot and saves you from the trouble of handling these files anymore.

You guessed right! there is a free online tool that lets you combine multiple PDF files into one single file. Now either it’s the multiple quotations files of your chemicals for project or book chapters, merge them and either send them or keep them as one. Use the tool here.

Edit PDF Files Online

I love to write, draw shapes and add different images to PDF files. I do it for different purposes including,

  • Making notes for myself while reading PDF
  • Replacing some text or the photo
  • Explaining any point in PDF before sending to someone

It matters how it serves your purpose but editing PDF is very helpful especially when you can do it online for free on this tool.

Password Protect PDF File Online

Encryption (simply Password Protection) of PDF file can help you to hide the content of your file and ensures the secrecy. There are two different ways to do. One is while creating the PDF file using Microsoft Office. This is the built-in feature of Microsoft Office. This can be applied to .Docx files also. How to Geek have explained it how to do it.

Alternatively, this can be done via an online tool as well. You just have to upload your file to this tool and this will password protect your PDF file. Above method is more recommended than this one.

Remove Password of PDF File Online

Removing password from PDF file is possible if the encryption used on the file is not so much strong. If the encryption is strong, you won’t be able to remove the password. There is an online tool that can remove the password from the PDF file for you. You can use this tool here.

Add Watermark to PDF File Online

Watermarking the PDF file can be very useful if you are going to make your report or paper public. This will help you in branding as well as promoting your organization or institution. Watermark can be added while creating the PDF file using your office software as explained on Microsoft Website.

If you have already created the PDF file, then you can do this now as well. Using this tool, you can not only stamp text on the PDF file as a watermark but Images as well.

Convert PDF to JPEG or PNG Online

If you are looking to send a specific graph, chart or photo from a PDF to someone then converting your PDF into JPEG or PNG can be helpful. You don’t need to send the whole file to the recipient. Webmasters or bloggers also require this when they want to show some part of the PDF online while overloading their web page.

There is no technicality in converting the PDF file into PNG, an online tool can do this for free in few seconds. You can do this using this online tool.

Convert Any format to PDF Online

If you are working with any application of Microsoft Office, you can convert it into PDF file using built-in save as function. But if there is any other file format you are working with or somehow if your that function is not working, you can use this free online tool to convert your any file format to PDF.

Save Web page as PDF

This is a very routine thing for me to save the web page as PDF. It helps me to read articles later offline or print them. You can also use this feature when you have a limited access to some web page or research article.

This can be done directly using browser action. Press Ctrl + P, a dialogue box will appear. Click on “Change” and select the option of PDF and then press the blue button of save as demonstrated in below picture.

JabRef is our top participant. The file format used by JabRef is BibTeX, the standard LaTeX bibliography format. This makes it compatible with almost every journal and search engine.

This free alternative of EndNote can import various file formats including PubMed’ XML, EndNote, and OVID etc. This citation manager is very light weight due to being Java-based. This EndNote alternative is compatible with Linx and Mac OS X as well.

GNU Octave – Free Alternative to MATLAB Suite by Mathworks

MATLAB is a mathematical software widely being used by almost in every field. From signal processing to designing models for genetics, everyone is crazy about this software. Unfortunately, complete package of this software cost a lot of money to its users so they are compelled to use pirated versions of this software.

SPSS by IBM is an analytics tool for statisticians. But its use is not confined to them only. Every researcher dealing with some data have to deal with it to save time. It’s a more advanced and feature-rich form of Office Excel designed to perform statistical operations on data for analysis.

Not only you have to pay a huge amount of money while purchasing the activation for your SPSS but later on you need to pay again to renew your subscription and add advanced packages in your software suite.

PSPP comes as the best free alternative to SPSS distributed by GNU. It is very similar to the IBM SPSS software except for the following things,

  • It will not expire
  • No money needed to buy advanced features
  • Support for over 1 billion cases and variables

While reading and reviewing the PSPP – a better version of paid SPSS, I found no reason to prefer SPSS over it.
