⭐ Docbolt Pro (optional)
Docbolt PDF is free to use, with ads. Optional Docbolt Pro removes the ads and unlocks unlimited tool use, any file size, batch processing, 100-page scans, unlimited saved signatures, watermarks and page numbers. From $4.99/month, $29.99/year with a 7-day free trial, or $59.99 once for lifetime access. Prices shown in US dollars; local prices may vary.

Why file access? To show all your documents in one list, Android asks for "All files access". You can skip it and open single files with the system file picker instead.
