Filling in the pdf was great, however when I saved the file using "Save As" the text was not spaced out in the boxes but overwritten making it difficult to read.

I'd be interested in a WEBnar but I'm a disabled WWII VET and can't drive anymore! Youve made my computer operations easier for an old man!, Thanks, Bob Reynolds (ROBERT)

I really like it
I really like it. I find the tool great. I just wish I could drag and drop pictures from my desktop directly to the pdf without the uploading process.

My only use is to help my 14 year-old grandson with his Eagle Scout Service Project report.
I'm retired and have no further use for the program beyond next year when he has completed his Project.
2021-02-12
Excellent company. Not only does the PDF Filler work great, but when I asked for the annual fee to be refunded after I neglected to cancel my subscription, it was done so immediately and graciously.

Editing sections to look exactly like the scanned portion can be difficult and sometimes not possible.

Contact Support
Does OPPO have security?
OPPO attaches great importance to the safety of its products and services. We will update the system security patches through OPPO Security Emergency Response Center (OSRC) to ensure the security of information for each device and user.
Should I remove all certificates?
It just goes to show you that even technology has its trust issues. If an app gives you reason not to trust it, delete that certificate. If you do trust the app but want to show your device that you do, install the proof!
What happens if I remove all certificates?
You would usually remove a certificate if you no longer trust a source. Removing all credentials will delete both the certificate you installed and those added by your device.
Is OPPO private safe really safe?
Keeping this in mind, OPPO's ColorOS 7 comes with 'Private Safe' feature which is an encrypted space for your private files. Any file you add here will not be shown anywhere in the OPPO phone outside Private Safe, keeping the files absolute private to you even someone else uses your phone.
What happens if you delete all certificates?
Important: Removing certificates you've installed doesn't remove the permanent system certificates that your phone needs to work. But if you remove a certificate that a certain Wi-Fi connection requires, your phone may not connect to that Wi-Fi network anymore. Open your phone's Settings app. Encryption & credentials.
What is secure environment in OPPO?
Certified by the most strict ISO and ePrivacy certificates, OPPO manages to encrypt user information while storing and transmitting. In addition to receiving all the security provided by Android 11, owners of OPPO devices also enjoy augmented protection thanks to the changes brought to ColorOS 11.
