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. Honest limits worth knowing: Compress PDF flattens each page to a re-encoded image (great for scans, not ideal if you need selectable text after); HEIC conversion depends on your browser (Safari usually works; Chrome often cannot decode HEIC without a library we don't ship); Fill PDF Form is best-effort for simple AcroForm fields, not a full Adobe Forms replacement; and Word/Excel/PowerPoint ⇄ PDF genuinely needs a server-side engine, so it isn't included — this build only ships tools that can honestly run client-side.
Benefits of doing this in your browser
The same reason applies to every tool on this site, whether it's a PDF, an image, or a calculator.
Nothing to Upload
A file-based tool here reads your file directly into browser memory — there's no upload step to wait on, and no copy of your file ever sits on a server.
No Account Needed
Every tool works the moment you open it. Signing in is entirely optional, and only unlocks an activity log — never a feature a tool would otherwise refuse to run.
Nothing to Install
No app, no browser extension, no desktop software. Anything with a modern browser can run every tool here, including a locked-down work or school device.
Genuinely Free
No watermark added to a result, no daily conversion limit, no "upgrade to remove this restriction" prompt anywhere on the site.
Fast, Because There's No Round Trip
Processing starts the instant you click run — there's no queue, no upload wait, no server load to compete with other visitors for.
Works Offline, Once Visited
A tool you've opened once while online keeps working without a connection afterward — its page and processing libraries are cached for you automatically.
Who actually uses these tools
A cross-section of the everyday work this toolkit covers — most visitors are here for one specific task, not to browse.

How this compares to other free tool sites
The honest trade-offs — this approach isn't strictly better at everything, just different in a way that matters for privacy and cost.
| Feature | TechDriven Tools | Typical Free Tool Sites | Desktop Software |
|---|---|---|---|
| File privacy | Never leaves your device | Uploaded to a server for processing | Local, but needs install/updates |
| Account required | No, ever | Often required past a free limit | Usually a license key |
| Daily usage limits | None | Common on the free tier | None, once purchased |
| Cost | Always free | Freemium, often with ads or a paywall | Often a one-time or subscription cost |
| Installation | None — runs in browser | None — runs in browser | Download and install required |
| Works offline | Yes, once a tool's been opened | No — every run needs a server | Yes |
| Office format conversion (Word/Excel/PPT) | Not offered — no reliable browser-only engine exists | Usually offered, via a server | Usually offered |
Questions people actually ask
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.
