The thing that sold me: turn on airplane mode and it STILL works. Nothing gets uploaded anywhere, it all happens right on your phone. I deal with sensitive work documents and I'm not throwing those at some random website. Worth it for the peace of mind alone.
Fast offline converter
Fast offline converter and file editor. A bit too many functions and clattered, but works fine
Nice on device converter
Nice converter for pdfs, fast video compression. I like the presets functionality a lot and use it to automatically edit all my incoming invoices
Great on device converter
A lot of conversion options to convert image to pdf, use OCR, image and video compression and more. I use it a lot and especially I like the idea of workflows, to combine several conversion methods in a workflow and apply it to all the batch of files I have at once. Saves a lot of time.
Very functional on device converter
many options of on device conversions for all types of media and documents. Like it
Everything stays on my phone
Easy to use, and most importantly, it converts and keeps my information stored on my phone.
