How we build

Three promises on every tool page — not marketing footnotes.

  • Fast & focused

    Each tool loads only what it needs. Results update as you type — no empty “Calculate” theatre.

  • Privacy-first files

    Image and PDF utilities run with Canvas / pdf-lib in your browser. Open Privacy proof on any file tool after a job.

  • Honest explanations

    Formulas, worked examples and FAQs sit next to the workspace so beginners and specialists share one source of truth.

Browser-local

Your files never need our servers

Compress, convert, merge or split in the tab you already have open. Calculators keep inputs in the session — shareable links only include what you put in the URL.

Built by The Conversion Berg

TCB Tools is an independent utility platform — not a growth hack, not an upload marketplace. We ship practical browser tools and keep the story straight about privacy, limits and math.

Who we are for

Marketers checking ROAS or UTM hygiene. Operators pricing work with margin and markup. Designers and PMs compressing creatives or merging PDFs without uploading client files. Developers formatting JSON or encoding strings between tickets.

What “browser-local” means

When a file tool says it runs in your browser, bytes are handled with Canvas, pdf-lib or pdf.js in your tab. We do not take those uploads for basic compress, convert, crop, merge or split jobs. Calculator inputs stay in your session; optional share links only encode the numbers you choose to put in the URL.

How we stay useful

Every tool pairs the interactive workspace with definitions, a worked formula where it matters, interpretation notes and FAQs. Guides link back into tools with example numbers. Workflows chain common jobs without a third-party suite account.
