What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Overall the format is excellent -- the clearest, fastest and most accessible set of URL instructions I've ever used -- EXCEPT haven't yer succeeded in getting a doc e-signed! Maybe we were missing a step. The doc got e-sent to the signer, but all he ever got was the sample doc to fill out -- but it wouldn't let him fill it out. and just kept popping up the sample doc. Even tho ' it side we'd successfully down loaded the doc - but it appears it kept downloading the same sample doc and not the one I'd sent him to sign,

Easy to use
Easy to use. Only one downside - can't bring in any other types of fonts. That would be helpful. Other than that it's good for my needs.
