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's the difference between the presets?
"Allow all" lets every crawler access every page (Allow: /) — the right default for most sites. "Block all" disallows everything (Disallow: /) — for a staging site you don't want indexed. "Custom" lets you list specific paths to disallow while everything else stays allowed.
Can I block specific bots only, not all crawlers?
Not in this version — the generated file targets User-agent: * (all crawlers) with one shared rule set. For per-bot rules, add additional User-agent blocks to the downloaded file by hand.
Does adding a sitemap URL help SEO?
Yes — it tells crawlers exactly where your sitemap lives, which is a standard, low-effort way to help search engines discover your pages faster.
What syntax does the Disallow field expect?
Standard robots.txt paths, one per line — e.g. /admin/ to block a folder, or /*.pdf$ to block every PDF file.
Will "Block all" actually remove my site from search results?
It stops crawling going forward, but it isn't the same as instantly removing already-indexed pages — for that, use each search engine's own URL removal tool as well.
Where do I put the downloaded file?
At the root of your domain, exactly at yoursite.com/robots.txt — it won't be recognized anywhere else.
Can I preview the result before downloading?
Yes — a Copy to clipboard button sits next to the download option, so you can paste and check it anywhere first.
Is my input sent anywhere?
No — the file is built entirely in your browser from what you enter; 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 Robots.txt Generator
- Create a robots.txt for a new site without memorizing the exact syntax.
- Block a specific path from crawling — an admin panel, a staging area.
- Point crawlers to your sitemap explicitly.
- Fix a missing or misconfigured robots.txt quickly.
How it works
The tool assembles standard User-agent, Allow, and Disallow directives, plus an optional Sitemap line, into the exact plain-text format search engine crawlers check at /robots.txt before crawling a site.
A note on what robots.txt actually controls
robots.txt is a request, not an enforcement mechanism — well-behaved crawlers (Google, Bing, and similar) respect it, but it doesn't prevent access to a page, just discourages indexing by crawlers that choose to follow it. For genuinely restricting access to sensitive content, use real authentication, not robots.txt.
Why people search for Robots.txt Generator
Build a robots.txt with allow/disallow rules and a sitemap link. Bookmark /robots-txt-generator if Robots.txt Generator is part of your weekly workflow; the URL is stable and the tool stays free.
Robots.txt Generator sits in our SEO & Web 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 Robots.txt Generator is for
- 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.
- You need a result now and do not want another account wall.
- The file or text is sensitive enough that uploading feels wrong.
Recommended workflow
Generate the snippet or file locally → paste into your CMS or deploy repo → validate in Search Console or rich-result tests when it matters.
- Open Robots.txt Generator (also available from category hubs and ⌘K).
- Use the labeled fields or dropzone — options match what Robots.txt 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
- 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.
- 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.
Common mistakes with Robots.txt Generator
- Expecting Robots.txt 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 Robots.txt 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 — Robots.txt Generator
Is Robots.txt Generator free to use?
Yes. Robots.txt Generator on TechDriven Tools is free — no account, no watermark, and no paywall for the core workflow.
Does Robots.txt Generator upload my file or text?
No for processing. Robots.txt 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 Robots.txt Generator?
Use Robots.txt Generator for SEO & Web Tools jobs where privacy and speed matter: quick one-offs, sensitive inputs, or checking another app’s result without another upload site.
Will Robots.txt 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 Robots.txt Generator?
There is no server quota from us. Limits are your device memory, battery, and formats the browser can decode. Robots.txt Generator will not pretend to support server-only Office or cloud-AI pipelines.
How is Robots.txt Generator different from upload-based sites?
Upload converters send your content to someone else’s server. Robots.txt 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 Robots.txt Generator done quickly and privately, start at /robots-txt-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.
