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
How do I specify which pages to remove?
Enter page numbers and ranges like 2,5-7 — that removes page 2 and pages 5 through 7.
Can I accidentally remove every page?
No — the tool blocks a result with zero pages left, so you can't end up with an empty PDF by mistake.
Can I remove pages out of order, like "7,2,5"?
Yes — the order you type them in doesn't matter; matching pages are removed regardless of the sequence you list them.
Can I remove a range and individual pages in the same run?
Yes — combine them, like "2,5-7,10", and every matching page is removed in one pass.
What if I enter a page number that doesn't exist?
It's ignored — only page numbers that actually exist in the file are used.
Does removing pages affect the quality of the remaining pages?
No — remaining pages are copied exactly as they were, not re-rendered.
Can I remove pages from a scanned PDF?
Yes — removal works the same regardless of whether pages contain real text or scanned images.
Can I preview which pages will be removed before running?
Not as thumbnails — enter the page numbers and the hint text confirms the file's total page count, so you can double check your ranges before running.
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.
