What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I had to refile my last 4 years 1040 and all tax docs. After going through the IRS web docs but unable to edit them I found all the docs on the PDFfiller website. After a little work with the editors I was able to process professional docs. I bought a year sub and look to see if I can use this app for other business uses.

Easy And Fast PDF Form Filling Software! Works with all types of devices, so I can prepare a document for signature quick and right where I am. Pricing is very fair. It is sometimes a little slow and there is a bit of a learning curve but once those are overcome, it is practically flawless.

pdfFiller is a useful PDF editor and e-signing tool pdfFiller is a very easy tool to use if you find yourself needing to sign or edit PDF documents, but don't want to spend a lot of money on more expensive software. I appreciate how easy pdfFiller makes it to electronically sign documents or edit and convert PDF files. The instructions are easy to follow and within minutes you can merge, split or sign documents without to much effort. All in all I can't complain about the software. There were a few instances where I would download my signed document for it to turn out completely blank (in the free version), but then I'd just download it again and that usually solves the issue.

I have been using ********** and AirSlate for over a year now to create digital documents and digitally signable documents. The system is very user friendly and all the options to automate my digital forms are logical and intuitive. I highly recommend this product for creating digital forms.

I mislead them on my intentions for the service level that I required. Once I brought it to their attention, I answered 3 questions; and the matter was immediately resolved. Outstanding customer service comms. !!!

I signed up originally to utilise this service. Whilst I did not wish to continue with the service (just wouldnt need it again) I did struggle to cancel the service. I sent an email outlining my issue and got the quickest response back and my account fixed and funds returned. Great service if you do require all the time. Easy to use. Highly recommend.

You can reduce your file size by saving your spreadsheet as a binary workbook (.xslb) instead of the default format (.xslx). The default format is XML based, which is important if you're using your data with third-party programs because XML is an open standard.
The 5 most common reasons for Excel files getting too large are: PICTURES: If your spreadsheet contains lots of pictures, or some very large images. EXCESS FORMATTING: Excel sheets can contain millions of cells - and if you have formatting applied to them even without any data it can make truly massive Excel files.
This can be done by right-clicking the Excel file and choosing “Compressed (zipped) folder” under the “Send to” tab.
