I AM A TAX PREPARER SO YOU CAN IMAGINE AT THE BUSIEST TIME HAVING TO RUSH AND GO BUY FORMS OR ORDER ONLINE, IT WAS EASY VERY SELF EXPLANATORY. WOULD LIKE TO SEE ADDITIONAL FEATURES, SAVE THE EIN NUMBER, PREFILL THE SS AND MEDICARE WHEN YOU PUT IN THE AGI.

I love it for the most part. Just wish I could send a document to a person without knowing their email (ex. directly to their Facebook account) with the ability to view and sign not edit the document. Other than that, it's been great!

Besides being a great product Support is Outstanding Besides being a great product, I would like to express how good the support is.I worked with Sam for over an hour, He went way above and beyond helping me with my Zapier Integration. Most companies would have just said that is "out of scope" Or "not my problem" Not these guys, they logged into my computer and dove deep into it and fixed my problem. Also keep in mind, I am only on a basic plan and they treated me like I was spending $1000's of dollars with them.

How to send a fillable document that can be returned in a completed state I am new to using the pdf filler application in my business. When I sent my first document out, my client had a problem returning the filled out document. I used the chat feature to resolve my problem and received excellent help from Sam, who answered my questions and provided me with great resources.

What do you like best? I like the ability to electronically sign documents. What do you dislike? I wish I was able to edit the text in documents without the formatting getting messed up because it only allows for the addition of new text boxes or adding to existing ones which causes the formatting issues. What problems is the product solving and how is that benefiting you? It's solving the issue of having to print out and fax documents which can be time consuming. It has really benefited my company to be able to sign and send documents electronically making for a smoother more efficient experience.

Just plain user-friendly Very intuitive UX. Just easy to use that I don't even have to think about it. Normally I can see negatives with a product. Not this time however. Works great.

How to Make Picture Higher Resolution Using an Android App: Step 1: First open the app on your Android after installing it and choose photos from your Android mobile. Step 2: Now you need to select the output dimension. You can choose from preset or choose Custom to enter your own dimension manually.
You can increase the resolution of images to ensure that a photo you want to use can be adapted to your project. Resizing a low-resolution image doesn't add the additional detail that would be apparent in a high-resolution original photo, but it increases the usefulness of many images.
Choose Image >Image size. Maintain the current ration to pixel width to pixel height by selecting Constrain Proportions Under Pixel Dimensions enter your new values. Ensure that Resample is selection and choose an interpolation method.
Click the File tab. Click Options and then click Advanced. Under Image Size and Quality, use the drop-down to select whether you want the change to apply to a specific document or all new (and future) documents.
