About CbrTool
CbrTool is a free online utility platform that helps people get everyday digital tasks done in seconds — no install, no sign-up, no nonsense. Here is the story behind it.
Our Story
CbrTool was launched in 2023 with one simple goal: make the small, everyday digital tasks that everyone needs — converting a file, formatting some text, generating a password, looking up DNS records, optimising an image — fast, free, and frictionless.
Before CbrTool, doing any of these things usually meant downloading clunky desktop software, signing up for a service that would email you a download link an hour later, or paying for a "premium" subscription to a tool you only needed once. We thought that was broken. So we started building the toolbox we wished existed.
Today, CbrTool hosts more than 100 free browser-based tools across 8 categories — network, encoding, image, format conversion, SEO, text, security, and unit conversion — and is used by hundreds of thousands of people every month, from students and freelancers to developers, marketers, and small business owners.
Our Mission
To give every internet user free access to high-quality, privacy-respecting online tools that solve real problems — without paywalls, sign-ups, or malware.
Our Vision
To become the go-to toolbox on the web — a place where anyone, anywhere, can find a tool that works, in under five seconds, without thinking twice.

What We Stand For
Free, Always
Every core tool on CbrTool is free to use, with no hidden paywalls. We make money from non-intrusive ads, not from locking basic features behind subscriptions.
Privacy First
We don't ask you to sign up. We don't sell your data. Uploaded files are deleted automatically within 60 minutes. Period.
Fast & Lightweight
Our tools run in modern browsers with minimal server load. Most operations complete in seconds, not minutes.
No Bloat, No Malware
No fake "Download" buttons. No "Your computer is infected" scams. No toolbars. Just the tool you came for.
User-Driven
Many of the tools we have built came directly from user requests. If there's a tool you need, just ask — we read every message.
Honest & Transparent
We tell you exactly what a tool does, what data it touches, and how to reach a human if something goes wrong.
Beyond the Web
CbrTool is also the team behind the Comic Book Reader Android app, available on the Google Play Store. The app lets you read comics, manga, graphic novels, and e-books offline in popular formats like CBR, CBZ, CB7, and CBT — with full library management, bookmarks, and night mode.
The app and the website share the same philosophy: free, fast, ad-supported but not annoying, and respectful of user privacy.
View on Google PlayWho We Are
CbrTool is built and maintained by a small, distributed team of developers, designers, and digital tool enthusiasts. We work remotely, ship often, and obsess over the small details that make a tool feel "right" — clear buttons, sensible defaults, sensible error messages, and a working copy-paste.
We are not a giant corporation. We are not a venture-backed startup racing to "disrupt" something. We are a small group of people who use the web every day and wanted to make it a little better.
Want to join the team, or just say hi? Drop us a message — we read every one.
Frequently Asked Questions
Is CbrTool really free?
Yes. Every core tool is free to use, with no sign-up required. We are supported by non-intrusive advertising. Some advanced features in the future may be marked as "premium" — but the free tier will always cover the vast majority of what you need.
Do you store the files I upload?
No. Uploaded files are processed on our servers to perform the operation you requested, and are automatically deleted within 60 minutes. We do not use your files for training, marketing, or anything else.
Do I need to create an account?
No account is needed to use any of our tools. You can use everything anonymously, right from your browser.
Can I request a new tool?
Absolutely. Many of the tools on CbrTool started as user requests. Use the contact form and tell us what you need — if it fits our scope, we will add it.
How do you make money?
CbrTool is supported by advertisements served through Google AdSense, and in the future possibly by optional premium features or a paid Android app tier. We will never sell your data.
Is my data safe?
We use HTTPS everywhere, restrict internal access to data on a need-to-know basis, and follow industry-standard security practices. Read our Privacy Policy for the full details.
