看看我們的 使用者 怎麼說

My dad is a very frequent user at 70+ yo and I never ever received a call or a question or a complaint about this app, unlike many others 😂 it just works and never gives headaches of any kind!
u/Cyberpunk627 Reddit
I work in indigenous healthcare. … I need total confidentiality of my data, as you can imagine, and I need to split pdfs. Bento is the first time this trivial task has become possible confidentially.
ballantynedewolf GitHub
Really awesome tool. I’m in the legal field and have been stuck with Adobe because they do have pretty robust redaction tools, although it is super clunky and resource intensive. Bento is quickly gaining market share in my legal stack.
u/sewersurfin Reddit
BentoPDF provides tools that I have ended up using on a daily basis, and I can do it secure in the knowledge that my documents are remaining private. It just works.
Fubarpie Trustpilot
Huge fan of Bento PDF. We don't have a decent PDF suite at work so most of my colleagues turn to online tools that are likely to collect your data. I selfhosted Bento for my team and their reactions are very positive.
Schlemmy Lemmy
I've used it before for a job application! I needed to send them sensitive data. Tysm! Great intuitive UI, does what it says, and it's fast. 5/5
Lemminary Lemmy
BentoPDF is fantastic, I never knew something like this existed. … I fired Bento up and was done in under a minute.
suicidaleggroll Lemmy
A great open source software tool that has helped me deal with PDF's on numerous occasions. Support and use this project. It needs the love and attention to grow even bigger.
Jeffrey Jansma Trustpilot
Fantastic project. The workflow builder literally just saved me half a day of my life so huge thanks.

Thank you so much for this. We just started using it at our school.

My first reaction after trying Bento was "this is magic, how does this work?"
