edit your PDFs as the best. 1.- It's Free. although there are some functions that are paid, for daily use just a free account which is very good. 2.- Pretty friendly and friendly interface. Everything is understandable and the use of the program is very easy to understand. 3.- Its use can be integrated with dropbox, googlr drive, box and onedrive. 3.- You can use files that are in your pc, your cloud or in some website (in this case you just have to enter the link). 4.- with the built-in editor you can add images, scratch, write in the text, delete sectors, hide words or paragraphs with black, add lines, and many other things. 5.- You can save your work in pdf, word, excel or powerpoint format. It also includes the option to send via mail, fax or simply share the link. the bad thing, is that if or if you must register to use it, which perhaps is not something serious, but the program forces you to do so.

I found that I no longer needed pdfFiller but the subscription was renewed. Upon advising prfFiller they promptly refunded the subscription. A good and honest company.

Phenomenal Customer Service Due to the pandemic, like a lot of people I was forced to work from home. My employer doesn't adequately support us in this task and so one day as a matter of urgency I started the free pdfFiller trial for a month. I set a reminder to cancel my subscription but I didn't complete the cancellation. When the annual subscription fee was taken from my bank account I was devastated, it's a deduction I couldn't afford and my employer would not reimburse me. The team at pdfFiller were amazing. They ensured I successfully cancelled the subscription and they also processed a refund. The speed of response was phenomenal, their empathy towards someone who genuinely could not afford the subscription was so appreciated. Their customer service is like nothing I have experienced before. Keep up the great work.
