Why convert documents with pdfFiller?
More than a PDF converter
Upload a document in DOC, DOCX, RTF, PPT, PPTX, JPEG, PNG, JFIF, XLS, XLSX, or TXT format and instantly convert it to a high-quality, editable PDF. You can edit or sign your file, turn it into a fillable form, split it, or merge it with another document.
Convert documents in batches
Bundle several documents together and convert them all in one go - no need to process each file individually. Bulk conversion saves time and helps you organize your digital documents.
Preview and manage pages
Before converting your document, review and remove any unnecessary pages to keep it as clean as possible. Excluding pages you don’t need is a great way to reduce file size without sacrificing quality.
pdfFiller scores top ratings on review platforms
Was a bit cumbersome. When I searched for forms, the system kept giving me instructions on how to search instead of stating that an error was made or what to do to continue.
The billing is bogus and felt dishonest, but customer service fixed my problems after an email. These save well as pdfs but not as docs. I think the service should be less expensive, given apps with similar functionality.
Definitely Useful
As I mentioned, it makes the mailing process much more efficient.
PDFiller allows you to create and mail PDFs easily, saving you the hassle of getting an envelope, purchasing a stamp, maybe having to go to the post office, etc. For me that has been its greatest strength. The PDF customization interface isn't bad, but it's not immediately usable. It takes a little bit of time to learn how to use it effectively.
Right off the bat: I would not recommend this software to someone who isn't tech savvy or doesn't want a bit of a learning curve, for example, employers I've had in their 50s, 60s, and 70s who don't really "get" technology. The interface is fine if you just want to sign a document, but is not particularly intuitive when it comes to doing simple things like outright deleting portions of text. Too many steps.
How PDFfiller helped me
PdfFiller has saved me alot of time and money, I've used PdfFiller to sign documents for work and get them signed. Navigating through the software is easy, it allows you to not only upload the document needed to sign but email and a host of other different options which would definetly come in handy for those who are not tech savy and up to date with using the internet that well. Pdffiller has been not only a life saver but a time and money saver too. It is great for people who may not have to sign alot of documents or have to especially with the trial thats offered. I would highly recommend trying the program out.
I love the fact that PdfFiller is easy to navigate and it helps maintain formatting which is very important to the way people retain information and it keeps it just as it should be. PDf also allows you to implement watermarks and digital signatures which are very viable in the business industry. I also love the fact that software allows you a free trial so if your not satsfied your not obligated to stick to the program.
I cant really think of any cons about Pdffiller its very easy to use and worth the price.
PdfFiller ou rien
Très bonne expérience. Au début j'avais un peu de mal mais tout est venu très vite. Je l'utilise essentiellement pour ma paperasse professionnelle avec les administrations lorsque j'ai besoin de signer.Non seulement on fait des économies de papier mais en plus si on n'a pas d'imprimante ou qu'on se trouve sur le mobile ou la tablette on peut utiliser cette application. C'est top !
Pas besoin d'avoir un logiciel qui prend de la place dans l'ordinateur ou autre. Pas de risque de chopper un virus en téléchargeant !Facilité d'utilisation hors normes !
Je ne vois aucun point faible pour le moment. Si c'est le cas j'en ferai part.
