Good layout and simple to understand
Good layout and simple to understand. However, while editing I realised that it does change the original size of the item when it is converted the format.

Auto Renewal Charge
I was auto charged for a 2nd year for this service via PayPal. I do not need it and was surprised to see the charge. I contacted customer service via chat and they immediately issued a refund with no questions asked. I received an immediate email confirmation. That is customer service. Thank you pdfFiller.

Great Functionality, Amazing Customer Support, Great Experience Overall
This is a great platform, very seamless and user friendly. It does cost a bit so it would make sense if you use it quite often. More importantly, amazing support - the online chat response was quick (!!!), customer support staff was so friendly and understanding. Overall, such an amazing experience using this platform. Highly recommend you give it a go!

I filled out forms before purchasing app and thought it was saved. After I purchased the app I could not find my document. I texed with a customer service rep, he was no help and quit the communication.

Learn how to use the pdfFiller PDF compressor
While pdfFiller allows you to create, edit and e-sign PDFs, you can also easily reduce a PDF file size. This is useful when you need to send a large PDF document by email or fax, or download it to your device or cloud storage, when your internet connection is unstable. You don’t have to install additional software or switch between multiple apps — all the functionality for compressing a PDF online is available in your account.
Start by uploading a PDF to pdfFiller. Click ADD NEW and choose how you’d like to add a PDF to your account. Don’t forget that you can find a fillable PDF in our online library of 25 million documents. Ask your teammates for a specific PDF or create your own document from scratch.
To make a PDF smaller, split it into several documents. Select the PDFs you want to compress in the pdfFiller dashboard or in the folder where you store them, and click Split.
Split the pages of your large PDF into separate documents. These new documents will be saved as a downloadable ZIP file.
After you've selected pages to shrink a PDF, click Split. Then, select the destination where your document will be saved — Desktop, Google Drive, OneDrive, Dropbox, Box. Then click Download Now.
To select pages for another document, click Create another document and select the pages you need.
That’s it — you now have several small PDFs that can be quickly shared or edited. To use the pdfFiller PDF size reducer one more time, return to your dashboard.
