12d Synergy
12d Synergy and its ability to handle all file types really suited the engineering industry.

As per my knowledge and experience, Small PDF is well suited when we want to convert the large and bulk processing on the images to convert them into a single file and share. I found it well suited for college students because daily they scan multiple images and merge them to send as a single assignment file. Smallpdf has the future in the education field. Sometimes it is less appropriate for the people who want to share official documents by converting them into pdf without a watermark. I personally really like the Small PDF, it really helped reduce the difficulty of sending files, and photos to others.

- It has everything I'm not sure what I will say. E-sign, Share, convert. You can give an option in upload priorities features which I can see later.
- Background remover thing also you can add in it. So I can remove the unnecessary thing from an image.
- You can add a chatbot for help.

I give this rating to Smallpdf because it comes with a large array of tools and gadgets. It allows not only pdf reading but also mixing, splitting, conversion to and from pdf, pdf compression or protecting. It is really complete and it works excellent compared to other much more expensive alternatives in the market.

The output quality of the results produced by this software is very good. In some of the situations where the size of the files are big, this software takes time to upload the files but the download speed is quite good and the quality of the documents are satisfactory. PDF compression results are amazing in this software. It reduces the size without compromising on quality.

Everything is so simple and works so well, you shouldn't need support, but on the one occasion in several years that I needed it, support was quick and courteous.

Alternatives Considered
12d Synergy
Hands down prefer 12d Synergy. Bentley ProjectWise is overly complex, expensive and has a very cluttered interface.

I think that Smallpdf stacks up against its competitors in terms of easiness of use. The tool is very user-friendly, every feature is communicated in an efficient way and very simple to user so the user doesn't have to be particularly good at using software. Its features are superficial when compared to Acrobat but easiest to use for sure.

12d Synergy
- 12d Synergy has solved our multiple office syncing issues, adding the ability to have staff from remote offices collaborate together on projects.
- Email saving used to be a nightmare, however, staff finds 12d Synergy's email saving easy to use and are able to search for saved emails quickly.

- It has definitely increased efficiency. Lower paid employees can complete a simple task with Smallpdf rather than having a higher paid employee use their time to do it differently.
- Smallpdf decreases the customer-response time. Being able to send over the proper sized file quickly makes us look great!
