pdfFiller scores top ratings on review platforms
I needed to fill out a one-off 6 page form and was looking for a free app to do it. When I Googled for this you came up and I did not track it was not free until I completed the form. Then I was "stuck" b/c I needed it asap and the request for payment did not come up until the end. I was not happy and would never have used the program had I tracked what happened. That being said, it was an excellent program and if I had to fill out forms routinely, I would recommend it. But since I don't need this app, please cancel my subscription.
Great for easy form creation for end users
I love that you can make not only nice, user-friendly forms, but they become user-intuitive with this product. This takes the process ahead of just creating a Microsoft Office form, but allows you to create sophisticated forms that can be filled and even electronically delivered.
Often the layout gives me trouble or won't let me create form boxes in the appropriate area because it keeps snapping them to the grid, which might not automatically line up to my form fields as well.
Very helpful in my law practice.
Ease of filling out a variety of documents.
Easy to use. I like being able to switch from the wizard option to the self fill-out option. It is usable with all the legal forms I fill out.
I do not like how I cannot change font size when using the wizard to fill out form. Sometimes I don't have enough room in the space to type what I need. I also don't like how you lose what you have filled in if you switch from the wizard half-way through.
it did take me awhile to figure things out because I am older, I didn't realize that I couldn't upload my documents until I subscribed to the free trial
It's ok. While I rewrite the original words into another language, I want to down the line to look natural but it's not... because the line just leaves that much space
Great versatile tool
Great versatile tool. Was very pleased with its performance. They even gave me a month refund when I didnt complete the cancellation of subscription properly. Very pleased with their performance and professionalism.

How can I efficiently optimize PDF size for Mac without losing quality?
To optimize PDF size for Mac effectively, you can use the built-in Preview app. Simply open your PDF, go to 'File', select 'Export', and then choose 'Reduce File Size' as the Quartz Filter. This method minimizes the file size while maintaining acceptable quality for viewing and printing. Additionally, consider utilizing pdfFiller’s tools to merge or delete unnecessary pages, which can further reduce file size and enhance document performance.
What tools are available for optimizing PDF size on a Mac?
Several tools exist for optimizing PDF size on a Mac, including Preview, Adobe Acrobat, and online services like pdfFiller. Preview is a built-in option that allows basic compression. Adobe Acrobat provides advanced features for document management and automation, allowing bulk size reductions. For maximum flexibility, pdfFiller enables cloud-based optimization while ensuring security and cross-platform compatibility, making it ideal for remote professionals and legal teams.
Is it safe to use online services to optimize PDF size on my Mac?
Using reputable online services, such as pdfFiller, to optimize PDF size on your Mac is generally safe, provided you follow security protocols. Always check the site's data privacy policies and ensure it encrypts documents during upload and download. Online optimization offers convenience, but if the document contains sensitive information, consider using offline tools like Preview or Adobe Acrobat for enhanced security while optimizing your PDF size.
How does optimizing PDF size improve document sharing on a Mac?
Optimizing PDF size significantly enhances document sharing efficiency on a Mac by allowing faster uploads and downloads. Smaller files are easier to email and share through cloud-based platforms like pdfFiller. This improves accessibility for remote professionals and teams needing quick collaboration. For best practices, aim to keep your PDFs below 5MB for seamless email delivery while maintaining essential document content and quality.
Can optimizing PDF size affect the document’s security and integrity?
Optimizing PDF size should not compromise the document’s security or integrity if done correctly. When using tools like pdfFiller, the optimization process maintains password protection and permissions intact. However, improper compression can lead to loss of image quality or alterations in document formatting. Always verify your PDF after optimization to ensure that all security protocols remain effective and that the document appears as intended.
What are some common mistakes to avoid while optimizing PDF size on a Mac?
Common mistakes to avoid when trying to optimize PDF size on a Mac include neglecting to check document integrity after optimization and over-compressing images, which can degrade quality. Another pitfall is failing to utilize the right tools—relying solely on Preview might not provide sufficient reduction for complex files. For comprehensive results, use pdfFiller for its advanced document management capabilities and ensure you assess the final file size and quality before distribution.
