What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I've only used this service once, and I'm pleased with the outcome. My document looked more professional and I will use this service again. I think it's a bit pricey, so I suggest the company use a "one-time-purchase" option or free trial before buying.

Seems user friendly for the most part. It would be nice if the documents could be automatically opened in Drive without all of the signing in process each time

Highly Recommended
Excellent experience. It saves me a great deal of time. Cost effective.
The software is very easy to use. A real timesaver.
Sometimes it is a little slow in saving/processing various functions.

The application itself is amazing..
The application itself is amazing... everything works great... awesome features... easy to use... convenient... BUT... as with all of these services... they threaten you with a ridiculous amount ($96 for the basic annual subscription) if you forget to cancel your membership... and if I pay $96 I want lifetime access to something... or I'm not doing it, period. That's insane. It costs them next to nothing to maintain this website... it's just advertising. Oh, and they come up as a free online editor but then you gotta sign up for the trial and everything else... the hassle never ends. If this place let everyone use it for free they could make a killing on all the advertising they could sell... and everyone would get a free editor... anyway, I digress... enjoy the app!

How do I fax a large file?
Log into fax and click Share Large File. Then enter recipients' email addresses. Click Upload Files and select the file(s) you want to share. You can add multiple files up to 1 GB total. fax will send your recipient(s) a secure link where they can access your files.
How many pages can I fax at once?
There is no set limit to how many pages can send at one time in fax transmissions. Fax transmission standards do not have a theoretical length and size limit. There may be, however, physical limits to the ability of the receiving fax machine, fax service, or fax software.
Can you fax multiple pages at once?
When sending a multiple-page fax, it is important to note the total number of pages, including the cover sheet, so that the recipient can be sure that she receives all the pages. Once complete, your fax machine may print out a transmission report that will indicate how many pages were sent.
How long does it take to fax 50 pages?
An average fax page is about 100K. Say you expand this to be a 5-megabyte file, an often recommended limit, so that's 50 pages. It will likely take you about 50 minutes to an hour to send the entire document on a newer model. That's assuming the pages are text.
How long does it take to fax 20 pages?
For documents that contain mostly text it usually takes approximately 1 minute per page for the document to be delivered. For documents that contain graphics (e.g. scans of documents), or for faxes that are being sent through a slow phone line, it may easily take 5 minutes per page or more to be delivered.
How large can a fax be?
The default max number of pages that the Brook trout Call Parameters allows is 30. Any faxes larger than this will fail when attempting to send. If the fax you are sending has fewer than 30 pages, it's still a good idea to check the max page settings before contacting support as someone else may have changed them.
How long does it take to fax 100 pages?
Time required for transmitting fax depends on quality of the phone line, and content that is being sent. For documents that contain mostly text it usually takes approximately 1 minute per page for the document to be delivered.
How many pages can be faxed at once?
For traditional fax machines, it's recommended that you submit 50 pages or fewer. For an easier and reliable transmission, start with batches of 15 pages. Fortunately, online fax services are on the rise these days.
