What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I had a problem printing a draft of a form. "Blocked plug-in".
Had a chat with Paul on the site, and followed his suggestions for a fix.
Then was able to print the form. I am a new user and have yet to make changes to the form and print it.
Hoping for the best with that. Thanks, Verne

I am pleased that I can resend my document to a recipient because I initially documented the recipient's email address incorrectly. I was able to find out how to do this with all the helpful tabs and support information

Needed immediate access to a form and an option for signatures and PDFfiller worked really well for me. I signed up for the wrong plan but didn't realize it and someone from PDFfiller contacted me and asked how I would like to proceed. They also refunded my money for the incorrect plan,and made sure I had the correct amount charged for the correct plan. Forms are easy to use. Very impressed so far.

works fine, just hate that PDFfiller does not hold passwords for very long. use this account on two computers and always have to reset password from one to the other!

This program works great!
This program works great, sometimes things are a little off once you download and certain documents are easily editable while others can be a pain in the butt. Overall I like it & I think it's great. I would definitely use it & recommend it.

What do you like best?
It is much easier to use than Adobe Acrobat. Much more intuitive functions and file management. It has saved me a ton of time with the cloud storage of documents. I have used effectively for construction related documents.
What do you dislike?
Very rarely I have needed to use another platform because some municipalities require it but 98% of what I need to do is supported.
What problems are you solving with the product? What benefits have you realized?
Remote completion of forms and extracting text from PDF documents mostly.

I love the product
I love the product, however the one improvement I would like to see is the ability to combine documents into one or insert pages from a different document.
2020-06-03
Easy to execute the changes needed…
Easy to execute the changes needed without much instruction. Saving in the pdf filler on One Drive was slow (undoubtedly Microsoft's problem).

Free trial
Edit: I appreciate the clarification and the time they took to reply to my initial review about the free trial. I will give it a go now and happy to leave it at 5 stars.
Cheers!

Can you convert low resolution high?
Converting a low resolution JPEG file to a high resolution will not improve its quality. If you want to increase the size of a picture, it is easy to do with paint by using the command “resize” and increasing the horizontal and vertical percentage of the picture.
Can you increase the resolution of a photo?
In order to change the resolution of your image, you will need a photo editing program (Photoshop, Windows Paint, Picnic, PhotoS cape, etc). If you need to resize your image for email or web, you can change the pixels or the image size, which will change the resolution of the image.
How do you increase the clarity of an image?
Sharpen it to make it more clear. Adjust the light/brightness and contrast of the image. Adjust the color level/temperature of image to make it more effective. Apply various photo quality enhancing built-in effects to make it more clear and sharper.
What happens when you increase the resolution of an image?
Higher resolutions mean that there more pixels per inch (PPI), resulting in more pixel information and creating a high-quality, crisp image. Images with lower resolutions have fewer pixels, and if those few pixels are too large (usually when an image is stretched), they can become visible like the image below.
How can I improve the quality of a photo?
Open the image you want to edit. Resize the image. Crop the image. Reduce the image's noise. Retouch areas of fine detail with the clone stamp tool. Refine the image's color and contrast. Fine tune the image with various tools. Apply an effect to the image.
