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 uses a small on-demand converter when the browser cannot decode HEIC natively (Safari often works without it); 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.
Questions people actually ask
What does it actually do to the text?
Lowercases it, strips accents, removes anything that isn't a letter/number/space/hyphen, then replaces spaces with hyphens and collapses repeated hyphens — the standard "URL slug" transformation most blogging platforms apply automatically.
Does it handle accented characters, like é or ñ?
Yes — accents are stripped to their base letter (é becomes e) rather than dropped or left as a broken character.
Does it update live as I type?
Yes — the slug preview updates instantly with every keystroke, no separate run step needed to see it.
What happens to numbers?
Numbers are kept as-is — only letters get lowercased; digits pass through unchanged.
Can I use underscores instead of hyphens?
No — hyphens only, since that's the standard convention search engines and most platforms expect for URL slugs (Google has historically treated hyphens as word separators, unlike underscores).
What if my title is entirely symbols or emoji?
Anything that isn't a letter or number gets stripped — a title with no actual letters/numbers left after that would produce an empty or very short slug.
Is there a length limit?
No hard limit enforced here, though very long slugs are generally worth shortening by hand for readability and SEO, regardless of what this tool allows.
Is my text sent anywhere?
No — the transformation happens entirely in your browser; nothing is transmitted.
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.

Why use Slug Generator
- Create a clean URL for a blog post or page title.
- Standardize slugs across a content management system.
- Generate a filename-safe version of a title.
- Avoid manual errors from hand-editing a title into a URL.
How it works
The title is lowercased, accented characters are normalized to their plain equivalents, anything that isn't a letter, number, or space is stripped, and remaining spaces become hyphens — the same conventions most CMS platforms (WordPress, Jekyll, and others) use to generate a slug automatically, run here instead as a standalone tool.
Why slugs matter for SEO
A clean, readable slug (/how-to-merge-pdf-files) is both more useful to a reader scanning a URL and generally easier for search engines to parse than an auto-generated ID or a title left un-encoded with spaces and symbols. Keeping slugs short, descriptive, and consistent across a site is a small but genuine on-page SEO habit.
Why people search for Slug Generator
Turn a title into a clean URL slug. Searchers looking for “Slug Generator free” or “Slug Generator no upload” usually want speed plus privacy — that is exactly the TechDriven Tools model.
Slug Generator sits in our Text Tools group. The page is built so you can finish the job without creating an account, installing a desktop pack, or sending the payload to an unknown converter API.
Who Slug Generator is for
- You need a result now and do not want another account wall.
- The file or text is sensitive enough that uploading feels wrong.
- A desktop suite is overkill for a one-page or one-photo job.
- You want a second opinion after another converter produced a weird output.
Recommended workflow
Paste the draft → transform → copy back into the document where the text lives → re-read for tone.
- Open Slug Generator (also available from category hubs and ⌘K).
- Use the labeled fields or dropzone — options match what Slug Generator actually does.
- Run the tool and wait for local progress to finish.
- Download or copy the result, then verify on the device where you will share it.
Tips that improve results
- Keep the original until stakeholders accept the download.
- Rename the output with date + purpose before you attach it to email.
- On phones, plug in power for large PDFs, videos, or spreadsheets.
- Prefer UTF-8 text for developer converters; weird encodings cause most “broken” results.
- Start with a non-sensitive sample so you learn the options before the real file.
- Change one setting at a time when you are comparing quality or layout.
Common mistakes with Slug Generator
- Expecting Slug Generator to replace a full desktop suite for every edge-case format.
- Skipping a sample check and discovering a bad export after the original was deleted.
- Chaining many lossy image/PDF steps when one careful pass would have been enough.
- Using a public computer without clearing downloads afterward.
Privacy model
Processing for Slug Generator is designed to stay in the browser. Laravel serves the page; it does not receive your file bytes for conversion. Optional Supabase auth only stores which tool you ran and when — never filenames or contents.

FAQ — Slug Generator
Is Slug Generator free to use?
Yes. Slug Generator on TechDriven Tools is free — no account, no watermark, and no paywall for the core workflow.
Does Slug Generator upload my file or text?
No for processing. Slug Generator runs in your browser tab. Optional sign-in never stores file contents — only tool names and timestamps if you enable history.
When should I use Slug Generator?
Use Slug Generator for Text Tools jobs where privacy and speed matter: quick one-offs, sensitive inputs, or checking another app’s result without another upload site.
Will Slug Generator work on my phone?
Yes in a modern mobile browser. Large inputs can take longer because your device does the work locally.
What are the limits of Slug Generator?
There is no server quota from us. Limits are your device memory, battery, and formats the browser can decode. Slug Generator will not pretend to support server-only Office or cloud-AI pipelines.
How is Slug Generator different from upload-based sites?
Upload converters send your content to someone else’s server. Slug Generator keeps the transform on-device whenever the format allows, which is the safer default for confidential documents, photos, tokens, and configs.
Bottom line
If you need Slug Generator done quickly and privately, start at /slug-generator, run it once on a sample, then process the real input. That is how TechDriven Tools stays competitive: honest capabilities, labeled UI, and content that matches what the tool actually ships.
