I thought I would use the free trial and then cancel... I have found myself using it over and over again. It has saved me lots of paper and much time.

I had a hard time finding the correct form, but sent a help message and the support team sent immediately a site to find the correct form. I was blown away the speed of the help I received, amazing.
Charlotte M
It's made my reporting easier. It may be that I don't know everything to do on this site, but it would be nice if I could resize the boxes on my form.
Penny B
I am in a tight spot trying to complete personal paperwork with arthritis my writing is horrible, PDF saved me time and stress,not to mention I never used it before.Very user frindely.
Deborah S
What do you like best?
I really like that PDFfiller is a very user friendly and employs a lot of the same standard editing tools commonly found in simple office software like Microsoft Word. It's a great step up from the standard Acrobat Reader and also has an easier learning curve than some of the more advanced Adobe PDF products. Being able to sign documents electronically is another strong feature.
What do you dislike?
When I edit a document that has more than one page, I am unable to perform a copy and paste across multiple pages, which is a bit annoying when trying to standardize items across one document. Saving documents is also very easy. We can save the document to any one of my computer folders or a cloud storage account.
Recommendations to others considering the product:
I think that PDFfiller is a very effective and easy-to-use PDF editor and converter. For the price and functionality, it's definitely worth checking out, in my opinion.
What problems are you solving with the product? What benefits have you realized?
Since we often deal with many types of text documents, especially Word documents, PDFfiller has really helped to enable conversions of Word documents to PDF, which are more ideal for certain things like printing. We can also convert PDF files to Word, which greatly reduces our need to perform time-consuming typing. In general, PDFfiller has been a great tool for working with PDF files with its intuitive interface and clear functionality.

Gary Wong, MBA
pdfFiller is great so far pdfFiller is great so far, but I would like a bit more comprehensive editing tools. For example better alignment options for fields, even spacing, more flexible sizing options, and maybe support for tables. Also, right-alignment of fields works on-screen, but always prints left-aligned. Other than that, the ease of use and clean interface are a pleasure to use.

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 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.
EZGIF is a versatile and user-friendly online tool designed for creating and optimizing GIFs. It offers a wide range of features, including resizing, cropping, reversing, and converting GIFs, as well as optimizing them to reduce file size without sacrificing quality.
The GIF format uses LZW compression, which is a lossless compression method. However, because GIF files are limited to 256 colors, optimizing an original 24‑bit image as an 8‑bit GIF can subtract colors from an image. You can choose the number of colors in a GIF image and control how colors dither in a browser.
