No tech savviness required
If you are working on a presentation with a wide array of different files; for example, the accounting spreadsheet, PowerPoint presentation, and notes saved to Word, MergeFil.es is a cool tool to merge them together without the need to download any software.
MergeFil.es can combine and merge multiple file with various formats, including: PDF, MS Word, MS Powerpoint, MS Excel, images, html, and .txt files, into one cohesive PDF, Word, Excel, mp3, or PowerPoint document. You can choose the placement of your files, moving them up or down so they appear in the order you need; this is especially helpful for presentations.
Also, the MergeFil.es software gives you the ability to compress your files as well. Keep in mind, that all of the files you want to merge will need to be in a single folder because MergeFil.es will not let you select from multiple location; not a huge problem, but good to know before you start uploading.
To use the software, simply visit the site and complete the four steps. First, select the files you wish to combine/compress/merge. You can select multiple files at once. Next, place the files in the order you want them. Then, toggle on/off compression Note, that if compression is turned on, it will take the file longer to generate, since it is shrinking the merged file. Finally, select the file type you wish your merged files to become and you can download your result.
A few things to note: you made need to tweak your downloaded result. Images may be placed on separate pages, when there is sufficient room for them to be on a single page. Excel sheets may separate files, just make sure you glance through your results before you take it to your presentation, or hand it over to your boss. But, for free software, it is definitely a tool that warrants a look.
