Reducing Email Attachment Sizes With Compression – Howtoshtab – how to, lifehacks, tips and tricks

in this video I’ll be demonstrating how to use compression to overcome attachment size limits in emails as an example i’ll be using gmail which has a maximum attachment size of twenty five megabytes i’ve prepared two scenarios where the size of the attachments exceed the limits enforced by gmail in the first scenario i’m looking to send pictures through email however i have exactly twenty five point one megabytes of pictures which is slightly over the gmail limit to get around this i’m going to combined all the pictures into a special compressed file which will be smaller in size file compression is included in windows and requires no additional software to compress files in windows first select all the files you wish to compress right click one of the selected files select send to and then select compressed zipped folder now that the compression process is completed a file with the extension dot zip has appeared in the folder this file should now have a smaller size than the combined total of the pictures sure enough when i view it in windows it has a total size of twenty four point nine megabytes whereas we previously had twenty five point one megabytes for all the photos together uh.

.. it’s important to remember that this file now contains all of the photos we selected earlier and if i launch it here you’ll see what i mean they’re all listed keep in mind that what i’m seeing here is actually enhanced by third-party software but in windows opening a compressed folder compressed file is the same is opening a folder so you will see the contents with all the photos much like what i am seeing right here at this point you may be wondering about the efficiency of the approach given that we saved only point two megabytes the pictures i chose to compress were all in the jpg file format and jpgs by nature are compressed images in fact many multimedia file types are already compressed significantly by the time they are produced on the other hand text files and executables are usually not so they tend to compress better at the very least compression reduces the number files of that need to be uploaded to an email client simplifying the act of moving them around in this case the recipient would receive only one file and after it is uncompressed on his side all the photos will be available and it only took one email in the second scenario i have significantly more pictures to send given that their total size is equal to forty four point one megabytes i will have to change my approach rather than compress all photos into one compressed file i will create multiple compressed files and send multiple emails while i could simply select a subset of the pictures and create two compressed files via the send to menu i will instead use a compression program called winrar winrar can be acquired from rar labs dot com and is free to evaluate winrar introduces a new compressed file format represented with the extension rar it is similar to the zip file but requires winrar to be installed it has a nice feature that allows raw files to be automatically split into parts which will be useful in my case to create a multipart rar file simply select all the files you wish to compress right-click any one of them and select add to archive this option will appear after winrar has been installed once winrar appears it will ask you for an archive name the archive format compression method and other options the one we care about at the moment is split the volumes what this will allow us to do is instruct winrar to limit the size of each part in the multipart set so since winrar requires bytes in this case split to volumes bytes we will need to use a free online converter which will accept the friendlier megabyte format and change that into bytes so i have a site right here which i will put in the description which will allow me to do just that so when i enter twenty five megabytes into this site and click on this button below it automatically provides me with the bytes kilobytes gigabytes terabytes right now we only want bytes so i will copy this and return to winrar i will provide it with the bytes in the field right here and click ok now winrar will start doing its work we simply have to wait and once it’s complete we will have two rar files you can see right here that it is already talking about part two we already have two rar files now that it’s complete i will show you the rar files right here scenario two part one and part two now what we can do simply attach each of these rars individually to their own emails so i have an email open right here in gmail i will drag the first rar file into it and i can send it and simply create a new email and send part two and once the person receives these rar files it’s really a simple as clicking on any one of them and dragging the contents elsewhere winrar figures out putting them together and you don’t have to worry about that so multiple files but they’re treated as one when they’re finally collected at the end so those were two scenarios that illustrated how compression could be used to get around attachment size limits if you have any questions about what i presented please feel free to leave me a comment i’d be happy to answer them thanks.
