Convert documents in batches
Bundle several documents together and convert them all in one go - no need to process each file individually. Bulk conversion saves time and helps you organize your digital documents.
Preview and manage pages
Before converting your document, review and remove any unnecessary pages to keep it as clean as possible. Excluding pages you don’t need is a great way to reduce file size without sacrificing quality.
pdfFiller scores top ratings on review platforms
Just subscribed but my first form was excellently done. Intuitive and easy to negotiate the Dashboard. I really liked the alignment lines that assist to keep things neat when typing data into the field. Look forward to learning more about the capabilities. Thanks
Impressive customer service (LIVE support)
I did not realise that my free trial expired until I got a charge for the month of December. I contacted 'live support' (which popped in in 20 sec) and Thomas was the most helpful I've ever experienced in customer service. He found out I had 2 accounts and when I explained to him that I actually only used the service once, he promptly offered me refund. I did not even expect one because I honestly thought this is another website that makes money by offering a trial and then charge you once trial is finished (which many of us would forget and only cancel when it is too late). But no, refund is already action, and he also cancelled my account as per my request with no fuss! Thomas, thanks for being extremely prompt and helpful! I will surely use this service next time. Thank you!
