Great software Excellent, the software is very easy to set up and use and gives me all the functions that I need to edit documents. Ease of use. It allows us to edit documents easily and send them out to clients for signature. Lack of choice of fonts. When you edit a document, the font is automatically changed, meaning you have to change the font throughout the document.

Really easy to use The web interface is really easy to use. The "wow" feature for me is that you can setup a default signature and copy and paste it on documents as you need. This has saved me from losing time with some legal documents I need to sign while I'm away.

If you try to run a general-purpose compression algorithm on something that's has already gone through a specialized compression algorithm (e.g, if you zip a video file), you're likely to get a larger file out. If you want your file both compressed and encrypted, then do the compression before the encryption.
When you compare data compression ratios, it is clear that you must apply compression before encryption otherwise compression will have no effect. The results from my benchmark show the performance as the average number of nanoseconds it takes to complete each operation.
This means the value of compressing data will not exist, as there should be no patterns in encrypted data. Due to this, differential cryptanalysis can be used against this method to determine the sensitive data's value. Compression then encryption is much more resilient to differential cryptanalysis.
Encryption turns your data into high-entropy data, usually indistinguishable from a random stream. Compression relies on patterns in order to gain any size reduction.
