pdfFiller scores top ratings on review platforms
Aside from the cost associated with its use, I love PDFfiller! It is easier to use than the typewriter function in Adobe Acrobat and I could place text exactly where I needed it. One other recommendation is adding a spell check when finishing up the document. Respectfully, -RPS
My need for a Blumberg standard lease was satisfied, however the number of typographical errors in the form were surprising and correcting them caused a change in the font!! Very frustrating!
I am able to find everything that I need with running my Bookkeeping Tax Prep business from T4's to GST remittance. The price is a great price as I am a small business, it is affordable to small businesses. I am glad that I found this and look forward to using it for a long time.

Reducing the amount of physical computer hardware in the office (scanners, printers) through the use of software such as PDFfiller.
What do you like best?
I like the choice of fonts because one can add changes or complete empty fields to a pdf and by using a different font from the original text it is clear that the additions are different from the original.. Also I like that one can add circles, check marks, "X" to a doc. And can erase portions of text.
What do you dislike?
I dislike that you have to pay extra to add or subtract pages from a pdf.
What problems are you solving with the product? What benefits have you realized?
My hand writing is very poor. So I use PDFiller to compensate for this deficiency..

To optimize a GIF, start by reducing the number of colors it uses. Since GIFs are limited to 256 colors, using fewer colors can significantly reduce the file size without losing much quality. Another approach is to resize the dimensions of the GIF. Smaller dimensions naturally result in a lighter file.
How many KB should a GIF be?
How Big Should a GIF Be? The best GIF size ranges between 15 KB and 1 MB. This value will vary for each particular file you export, and will be influenced by which platform you intend to use the GIF on. For example, most e-mail client software will encourage users to aim for GIF file sizes below 200 KB.
