What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
It is very good for the most part; however, the pop-ups are very distracting. Also, when filling up a table with numbers, is is hard to line them up.

Customer support was top notch. They resolved my print issues with my form. The reason I did not give it 5 stars and would not recommend is that I Googled for a form to fill out for a US Passport. I didn't expect to find one i could fill in on line. What was not apparent was that ONLY AFTER SPENDING 30 MINUTES FILLING OUT THE FORM did I find out I had to pay $20 to print, save, fax, email or share the form. Customer service was great, but did not want to sign up for a monthly pdf service or pay $20 for 1 form.

Recommendations to others considering the product:
It's well worth implementing PDFfiller in any organization, especially those which have ongoing needs of signatures. The cost savings in staff time alone makes it pay for itself!

The best image resolution for most smartphones is 640 by 320 pixels, although you should ideally maintain the aspect ratio of the original image or the output image will be distorted.
Visitors need to be able to read your web pages with ease, click links without zooming in, and navigate your site on a smaller screen. Without mobile optimization, users often struggle to read or navigate websites on mobile devices.
Here's how to optimize images for the web: Name your images descriptively and in plain language. Optimize your alt attributes carefully. Choose your image dimensions and product angles wisely. Reduce the file size of your images. Choose the right file type. Optimize your thumbnails. Use image sitemaps.
This includes photos that are correctly sized, compressed, and have the correct file format to ensure they look good on any screen size or resolution. Mobile-friendly images help improve user experience by providing better views when accessing content from a smartphone or tablet.
What does mobile-optimization mean? Unlike the mobile-friendly approach to your website, a mobile-optimized website is designed for smaller screens and built using a mobile-first approach that will reformat itself for mobile users.
What is image optimization? Image optimization is about reducing the file size of your images as much as possible, without sacrificing quality, so your page load times remain low. It's also about image SEO—that is, getting your banner and product images to rank highly on Google and other image search engines.
