The contract PDF is password-protected. You need to delete two appendices from it. The delete tool won't open the file because it's encrypted.
Unlock first, then delete. Two steps, both in Flint.
Step one: unlock with your password
Open unlock PDF, drop the protected file, enter the password, download the unlocked copy. This is your local copy with protection removed — you can do this because you have the password. The original protected file (on someone else's system) stays protected.
Step two: delete pages
Open delete PDF pages, drop the unlocked copy, select pages to delete, hit delete, save. Standard delete flow on a now-unprotected file.
Step three (optional): re-protect
If the trimmed file should also be password-protected, add a password to the saved output. Use a strong password. Share it through a separate channel from the file itself.
Cleanup
Once you've confirmed the trimmed, protected file is correct, delete the intermediate unlocked copies. Fewer unprotected copies in your downloads folder is better. The intermediate files served their purpose — they don't need to persist.
FAQ
Can I delete without unlocking?
No. Encrypted PDFs are opaque to delete operations. Unlock first.
What if I don't know the password?
Can't proceed. Get it from whoever sent the file.
Is unlocking and deleting safe?
Yes — both run in your browser. The file never leaves your device. The password stays local.
Does re-protecting use the same password?
You choose. Could be the same, could be different. Whatever fits your distribution.
Unlock, delete, re-protect. Start with unlock.
