What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Liking it so far. But when I'm using the eraser, line, or other tool, it automatically changes back to text add mode after saving the change I've made rather than staying with the eraser, line drawer, etc. If you did it this way b/c more users keep erasing, adding lines, highlights, etc when they intend to make only one change and start typing then nevermind. I would rather it stay with the eraser, highlighter, etc. and I'll switch back to adding text when I'm ready to do so. Hope that helps.

To Whom It May Concern, I need to let you know that I jumped the gun on submitting my prior severely bad review. Knoll G ended up figuring out the issue and assisted greatly in resolving it. She had much more patience than I had as I had been trying to figure out where everything had been changed to from when I used your site the year before. After 4 hours of much frustration, Knoll G saved the day. I would like to ask for you to somewhat disregard my initial review. I only say somewhat because I feel that the site had such a huge change from last year's "easy to use" formatting. I never needed to use support help. That said, I would like to praise Knoll G. She never gave up even when I did. Huge THANK YOU for not giving up Knoll! You're great and I hope you get some sort of reward for going above and beyond. I would also like to add a technical note...I don't know how everything is viewed on the companies side, but it was very difficult to work with support in terms of the chat box. Every time Knoll G gave me a direction to go and I went (which means the screen changed), I would lose the chat box and had to wait for Knoll G to type and send me something before the box would reappear and then I could respond. It only added to my then current frustration so your site coders might want to look into that.

I love that you can turn any document or picture into pdf. As a loan officer, I need copies of driver's license and social security. Everyone has a nice phone but the format is not PDF. This PDFfiller is the best. It only has a few fonts. That is the reason for the 4 out of 5.

Great experience! I was able to get the rental applications done for my house rental. Super easy to use. Clear instructions, I found enjoyable to use this software. I'm not that good with computers but I was able to use it without much difficulties. I can't think of anything that I didn't like. I had to take a little more time to find out how to get confirmation of my forms I sent, other than that it was fast and easy.

Ryan was extremely patient and persistent to solve the issue Ryan was beyond patient with me to solve my issue. I really felt like he was determined to have me understand the instructions he was giving me towards the solution. He used a few of approaches. One of which was sending me a visual with arrows.....That worked!!!! His patience and persistence is refreshing and truly appreciated.
