What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Love the software but a bit of a brain surgery to start with each new document. The links, steps and path for loading and working on documents need to be highlighted better for new users. Probably makes great sense to the programmer but new users have to hunt for the next link or button to click.

My Favorite PDF Signing Software I've been using PdfFiller for many years and I've gotten used to the interface and so to me, it's pretty easy to use, but I've dabbled with other online document signing software and I admit those are pretty easy to use. Some of its competitors seems to have pretty user friendly interfaces.

Great Product This software has helped mainly with electronic signature creation but also with overall PDF edits. The software offers a number of options for editing PDFs and is fairly user-friendly. It has an easy layout. I do not like the fact that the software can lag when working with slightly larger documents. It can also be time-consuming to learn more advanced features.

Just what I have been looking for Just what I have been looking for. Very easy to operate once you get the swing of it. Typing over erasures may be a bit tricky, but you have to insert text in a blank space and then you will be abe to move your text over the erasure without any difficulty.

First, open your file in Preview by selecting the file in Finder, hitting Space, and then clicking the Open with Preview button. In Preview, head to File > Export. In the export window, select the Reduce File Size option from the Quartz-Filter drop-down menu and then click the Save button.
Reducing the size is possible if your 20mb images are in an uncompressed format (RAW, BMP etc.). If you need to maintain the quality, you will need to use a so-called lossless compressor such as TIFF with LAW, PNG etc. JPEG will remove information and therefor also quality.
