Took me a while to figure out how to… Took me a while to figure out how to delete an entire page. My one suggestion would be to leave the previously used tool activated. I get tired of having to click on "eraser" when I'm trying to erase multiple blotches on a scanned article.

AMAZING CUSTOMER SUPPORT!! A+++ Product outperformed other PDF software for my needs at the time! Customer services are A++, an annual subscription fee was taken as I had forgotten to stop this after my use, upon emailing pdfFiller's 'Live chat' the refund was processed and I received a confirmation email of this from PayPal in less than 30 seconds! If it wasn't for Covid19, I would have continued the subscription, but after losing my job my finances are paramount! Hopefully I will be in a position to return to your service in future! Thankyou pdfFiller!
