PDF, image, developer, SEO, text, student and business tools — all free, all entirely in your browser. No upload, no account, no server ever sees your data.
The toolset
Focused tools covering the everyday PDF work — pick one to get started, no account needed.
How this actually works
Each tool runs entirely with JavaScript already loaded in this page — PDF tools via pdf-lib and pdf.js, image tools via the browser's native Canvas API, and everything else with plain JavaScript. Your files or input are read into browser memory, processed, and handed back as a download or copyable result. This page itself is served by a small Laravel route; Laravel never sees your files either. The only backend in use is Supabase, and only for two optional things: signing in with a magic link, and — only if you're signed in — a log of which tool you ran and when. Two things have real limits worth knowing up front: Compress PDF flattens each page to a re-encoded image (great for scan-heavy PDFs, not ideal if you need selectable text after), and Word/Excel/PowerPoint ⇄ PDF conversion genuinely requires a server-side rendering engine, so it isn't included here — this build only ships tools that can honestly run client-side.
Questions people actually ask
Which schema types are supported?
Article, Product, FAQPage, and LocalBusiness — four of the most commonly used JSON-LD types for everyday sites.
Do I need to know JSON-LD syntax to use this?
No — fill in the plain-language form fields for whichever type you pick, and valid JSON-LD is generated automatically.
Where do I put the generated code?
Paste it inside a <script type="application/ld+json"> tag in your page's <head> (or anywhere in the body) — copy the whole snippet, including that wrapping tag, which is included in the output.
Does this guarantee rich results in Google?
No — valid structured data makes a page eligible for rich results, but Google decides independently whether and how to display them. No tool can guarantee that outcome.
Does this validate against Google's specific requirements?
It generates schema.org-valid JSON-LD for the fields you fill in. For Google's own rich-result eligibility rules on top of that, test the final page with Google's Rich Results Test after publishing.
Can I edit the generated code afterward?
Yes — it's plain, readable JSON; edit it directly before pasting it into your site if you need a field this form doesn't cover.
Which type should I use?
Article for blog posts/news, Product for something you sell, FAQPage for a page with genuine Q&A content, LocalBusiness for a physical business location.
Is my data sent anywhere?
No — the JSON-LD is built entirely in your browser from what you type; nothing is transmitted.
Is this really free, and is there a file size limit?
Yes — no account, no paywall. Since processing happens in your browser's memory rather than uploading anywhere, the practical limit is your device's available RAM, not a server quota. Very large files (500+ pages) may run slower, especially for Compress and PDF→JPG.
Does anything about my file get sent anywhere?
No. Every tool runs with pdf-lib/pdf.js loaded in this page; your file is read into browser memory and never leaves it. The only network call this app makes for your account is Supabase auth — and that only stores which tool you ran and when, never file content.
Why isn't Word/Excel/PowerPoint → PDF included?
Converting Office formats accurately needs a real rendering engine (what Word or LibreOffice use internally) — no browser library does this reliably. Rather than ship a broken version, it's left out.
Does TechDriven Tools have OCR (text recognition)?
Yes — OCR PDF recognizes text in scanned or photographed pages using Tesseract.js, running entirely on your device, and gives you a searchable PDF or a plain text file. Nothing is uploaded for this either.
Can I use this without an internet connection?
Once the page and its libraries have loaded once, yes — the tools themselves need no network access. Signing in and viewing history do require a connection, since those talk to Supabase.
What happens to the "history" if I sign in?
Only a row per tool run — the tool's name and a timestamp. No filename, no file content, ever. You can see the full list any time via the History button.
Are the non-PDF utilities (password generator, JSON formatter, etc.) private too?
Yes — same rule as the PDF tools. Word Counter, Case Converter, Password Generator, UUID Generator, Base64, Hash Generator, JSON Formatter and JWT Decoder all run with plain JavaScript already loaded in this page; nothing you type or paste is sent anywhere.
