Use PDFfiller for my PDF editing and signing needs I use it quite often and it has made my life much easier. PDFfiller provides a lot of functionality for a low cost compared to other solutions. A few features were missing when I first started using it but they have added functionality and it's much better now.

Easy to use! Easy to upload files and edit them. Can add text, check boxes and even add wet signatures. All files kept in one place and can be easily downloaded back to my documents once edited!

Reasonable but not fantastic Pretty decent, I'm not sure it's the best PDF software available, but it's not bad and can complete most tasks you'd ask of it. The software works for the most part well and allows the signing and creation of forms, handy for mild administrative use. Support seems limited to live chat only, which is a bit of pain if something goes wrong. It could also do with a mobile app which I don't believe there is currently.

Awesome platform for everything to with… Awesome platform for everything to with PDFs. Would thoroughly recommend if you have document collation to do or any other form of PDF editing. The icing on the cake is the fast, polite and friendly customer service team.

Choose File > Save As Other > Optimized PDF, or Go to Tools > Optimize PDF, and then click Advanced Optimization. The PDF Optimizer dialog box opens.
When you optimize your PDF documents, you will get smaller size files as against non-optimize files. So, if you are tired of waiting endlessly to view the pages of your document, you can make things easier by selecting 'Save as Optimized PDF'.
If your PDF includes artwork that contains transparency, you can use presets in the Transparency panel of PDF Optimizer to flatten transparency and reduce file size. (Flattening incorporates transparency into corresponding artwork by sectioning it into vector-based areas and rasterized areas.)
Open the copy and choose Advanced > PDF Optimizer. Click the Clean Up tab. Select Remove Hidden Layers Content and Flatten Layers, and then click OK.
