I BUILD SMALL
THINGS THAT
SOLVE REAL
PROBLEMS.
ToolKB started with a simple observation: sometimes you do not need a bloated cloud subscription. You just need one focused tool that executes fast, works privately, and gets the job done properly.
Sometimes the obstacle is just one file.
An exam portal rejects a photo because it is 52KB instead of under 50KB.
A government form expects an exact 213x213 pixel canvas.
A phone saves in HEIC format when a portal only accepts JPG.
A customer needs a clean PDF invoice with a UPI payment QR.
Solving these everyday technical friction points should not require installing heavyweight desktop software or surrendering private personal documents to remote cloud storage.
That is the engineering foundation of ToolKB.
ToolKB
A focused collection of 80+ browser-based utilities organized across exam preparation, image manipulation, PDF workflows, and creator tools.
USEFUL
Focused utility that solves a concrete problem without unnecessary friction.
CLEAR
If a tool requires a complex tutorial, the interface should be simplified.
FAST
Local in-browser computing avoids upload latency and bandwidth bottlenecks.
ACCURATE
Targeted kilobytes and pixels match the exact specifications required by portals.
Zero-upload file processing by design.
When you resize a photo for an exam application, sign a document, or generate an invoice for a client, that data belongs exclusively to you. It should not sit in an unmonitored cloud database.
Every file transformation algorithm on ToolKB executes locally inside your web browser client using HTML5 Canvas, Web Workers, and WebAssembly. We do not store or transmit your images and documents over the network.
For registered users, optional account authentication, subscription state, and daily fair-use quota counters are managed securely through Clerk, Razorpay, and Supabase Postgres, while all file processing remains strictly on your local device.
