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
What does this actually show me?
A realistic mockup of how your page's title and meta description would look as a Google search result — including where each gets visually truncated if too long.
Does this match Google exactly?
It closely approximates Google's typical desktop and mobile snippet rendering, but Google occasionally rewrites a title or description automatically based on the page and query — this preview shows what you're providing, which is the strongest signal but not always the final guaranteed result.
Does it check title/description length?
Yes — both fields show a live character count and visually truncate in the preview exactly where Google typically cuts a snippet off.
Can I preview mobile vs desktop?
Yes — toggle between the two, since Google displays slightly different snippet lengths on each.
Does using this submit anything to Google?
No — this is a visual mockup only; nothing is submitted to Google or any search engine.
Can I preview a URL I don't own?
Yes — this only renders the title/description/URL text you type in; it doesn't fetch or verify anything about a real page.
Is my data sent anywhere?
No — the preview is rendered entirely in your browser; nothing you type is transmitted.
Does a good-looking preview guarantee better rankings?
No — this helps you write a compelling, correctly-sized snippet, but title/description text is only one small factor among many in actual search rankings.
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.
SERP Preview Tool, in depth
See how a title and meta description will actually look as a Google search result, before you publish them.
Features
Live Preview
Updates as you type, styled like a real Google result.
Character Counts
Flags when a title or description is likely to get truncated.
Desktop & Mobile
Preview against both sets of typical truncation limits.
Nothing Sent Anywhere
Just text you type — no page is fetched or crawled.
Why use SERP Preview Tool
- Check a title and description before publishing, rather than finding out it's cut off after Google indexes it.
- Compare a few title variations for length and how they read as a clickable headline.
- Show a client or teammate what a planned page will actually look like in search results.
- Pair with the Meta Tag Generator to write and preview a page's tags in one pass.
How it works
The title, description, and URL you type are rendered in Google's own visual style — right down to typical truncation lengths for desktop and mobile — entirely from the text you enter. Nothing is fetched from the URL you type; it only appears as text in the mock breadcrumb.
An estimate, not a guarantee
Google's actual truncation point varies by pixel width rather than a fixed character count, and it sometimes rewrites a title or description entirely if it judges a different one better matches the search query. This preview uses widely-cited approximate limits to catch the common case — an obviously too-long title or description — not a pixel-perfect guarantee of what Google will show.
