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 citation styles does it support?
APA (7th edition), MLA (9th edition), and Chicago (17th edition) — the three most commonly required styles for school and academic writing.
Which source types can I cite?
Websites, books, and journal articles — the three most common source types students actually need to cite, each with its own correct field set and punctuation per style.
Will this always match my institution's exact formatting requirements?
It follows the standard formatting pattern for each style, but individual professors, journals, or style guides sometimes have small local variations — always double-check against your specific requirements before submitting.
Does it look up the source for me?
No — you enter the author, title, year, and source details yourself. This tool only handles the formatting, not fetching or verifying the source.
Can I generate a citation for a source with no known author or date?
Yes — leave the year blank and it uses the standard "n.d." (no date) placeholder each style uses for undated sources; for no author, enter the organization or site name in the author field instead.
Does it build a full bibliography or reference list?
No — it generates one citation at a time, which you copy into your own reference list. There's no saved list or multi-source management.
Is my source information sent anywhere?
No — the citation is assembled entirely in your browser from what you type; nothing is transmitted.
Is this a substitute for a style manual?
No — for an unusual source type (a film, an interview, a social media post) or an edge case this tool doesn't cover, consult the actual APA/MLA/Chicago manual or your institution's writing center.
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.
Citation Generator, in depth
Generate APA, MLA, or Chicago-style citations for a website, book, or journal article — formatted correctly for the style you need.
Features
APA, MLA & Chicago
The three styles most commonly required in school and academic writing.
Three Source Types
Websites, books, and journal articles, each with the correct field set.
Instant
Formatted as soon as you fill in the fields.
Private
Nothing you type is ever uploaded or saved.
Why use Citation Generator
- Format a citation correctly without memorizing each style's exact punctuation and ordering rules.
- Switch between styles instantly if a professor or publication requires a different one than you first used.
- Build a bibliography entry for a source you already have the details for.
- Double-check a citation you formatted by hand.
How it works
You enter the author, title, year, and source details, choose a style and source type, and the tool assembles them into the correct citation format — the right punctuation, italics conventions (represented as plain text here), and field order for APA 7th edition, MLA 9th edition, or Chicago 17th edition.
Always double-check against your specific requirements
This follows the standard formatting pattern for each style, but individual professors, journals, and institutions sometimes apply small local variations on top of the base style. Treat this as a strong starting draft, not a final authority — verify against your actual style guide or writing center before submitting, especially for source types beyond the three covered here.
