What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
While I understand that you want to get subscriptions for a whole year and renew those subscriptions annually, I would prefer to have an invoice at the end of the year, so that I could decide if I wanted to continue using your service or not. I really resent automatice renewals. Hence I went with the month to month as my need for your program may only be for a short time.

I needed to use the service for an application I needed to use the service for an application! It was only needed once. The day I was going to cancel it due to no longer needing the service the money had already come out of my account. They immediately refunded it and even offered a discount if I wanted to continue using it. I highly recommend it was an easy to use service with many benefits packed in.

No, compressing and flattening a PDF serve two different purposes. Compression reduces the file size by eliminating data, potentially affecting the quality depending on the compression level. Flattening, conversely, will merge all visual elements into a single layer but does not necessarily reduce the file size.
How to compress a PDF? Put all of the PDF documents you want to compress (or just one) into a new folder. Right click on that folder. Select the “Send To” option and then click “Compressed (Zipped) folder.” A new . ZIP file will be created that contains your document(s).
Open the Layers panel (if the Layers panel is not visible, choose View > Navigation Panels > Layers). Click the Options pop-up, select Merge or Flatten Layers. Remember: flattening layers removes layers that aren't visible onscreen. Save > Print file.
