Every file you touch here stays on your machine.
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 SQL dialects does it support?
Standard ANSI SQL formatting that works well for MySQL, PostgreSQL, SQL Server, and SQLite alike — dialect-specific syntax is preserved as-is, just reformatted for readability.
Does it validate that my SQL is correct?
It formats and indents your query, but it isn't a full SQL validator — it won't catch a logically wrong query, only genuinely malformed syntax it can't parse.
Can I choose keyword casing?
Yes — format keywords (SELECT, FROM, WHERE, and so on) as uppercase or lowercase to match your preferred style.
Does it handle joins and subqueries?
Yes — nested queries, joins, and multi-clause statements are indented to reflect their actual structure, not just reformatted line by line.
Does formatting change what the query does?
No — only whitespace and casing change; the actual SQL logic, table names, and values are untouched.
Can I minify SQL as well as format it?
This tool focuses on making SQL readable. For the opposite (compacting a query), simply removing the extra whitespace this tool adds gets you back to a minimal form.
Is my query sent anywhere?
No — formatting happens entirely in your browser; your SQL is never transmitted.
Can I copy or download the result?
Yes — both a Copy to clipboard button and a Download button are available.
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.
SQL Formatter, in depth
Turn a dense, single-line SQL query into readable, properly indented SQL — with a choice of keyword casing.
Features
Auto-Indentation
Breaks clauses, joins, and conditions onto their own lines.
Keyword Casing
Format keywords as UPPERCASE or lowercase.
Dialect-Agnostic
Works for standard SQL as used by MySQL, PostgreSQL, SQL Server, and similar.
Instant
Formatted locally as soon as you run it.
Why use SQL Formatter
- Make a minified or copy-pasted query readable before reviewing or debugging it.
- Standardize keyword casing across a file or team, without hand-editing each line.
- Clean up a query before pasting it into documentation or a code review.
- Untangle a long query with multiple joins and nested conditions.
How it works
The query is parsed and re-printed with consistent indentation, line breaks before major clauses (SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY), and the keyword casing you choose — entirely in your browser, using a real SQL-aware formatting library rather than a naive find-and-replace.
Formatting, not validation
This reformats the structure of a query for readability — it doesn't check it against a specific database's schema or confirm it will actually run. A query with a genuine syntax error may still format into a readable shape; always test a formatted query against your real database before relying on it.
