How PDF Ninja Tools works

Three steps. No accounts. No fine print. The way PDF tools should feel.

01
Pick a tool

Choose from 20+ tools to merge, split, convert, compress, secure and more.

02
Drop your files

Most tools work right in your browser — files never leave your device. Advanced conversions use a secure server and files are deleted right after.

03
Pay only what you use

Your first document is free. After that, top up credits — no subscription, no monthly bill.

Powerful tools

Everything you need for your PDFs

Twenty focused tools. Each one does its job perfectly and gets out of your way.

View all

Organize

Rearrange, combine, split and annotate your PDFs.

Optimize

Shrink, repair and standardize your documents.

Convert

Move between PDF and other formats with confidence.

Security

Encrypt, unlock and control access to your files.

Built for people who hate subscriptions

Most PDF sites lock everything behind a $10/month plan. We don't. Pay cents, not dollars.

20+ focused tools

Convert, merge, split, compress, watermark — one job per tool, done right.

Pay only what you use

Top up credits when you need them. Light tools cost less, heavy ones cost a bit more.

Private by default

Most tools run entirely in your browser. Server-side conversions delete your file immediately after.

Try before you pay

Your first document is on us — no card, no signup needed to test the tools.

Pricing

Pay as you go. Cents per file.

No plans, no monthly fee. Buy credits once and use them whenever — they don't expire. Most conversions cost around 5–15 credits ($0.05–$0.15).
