Files you open here

Most tools on this site read your file in the browser tab and never send it anywhere. That is not a promise about how carefully we handle uploads — there is no upload. You can check it: open your browser’s network panel, run a tool, and watch that nothing leaves.

Every tool page carries a badge saying which of three kinds it is: it runs in your browser, it runs in your browser and can call our server for one step, or it runs on our server. Everything that is not the first kind is listed below rather than buried.

Tools that run on our server

• Broken Link Checker — Extracts up to 100 links from a page, or takes a pasted list, and checks each in parallel — status, redirect target and response time, HEAD first and GET when refused.
• CORS Tester — Sends the preflight a browser would send from a chosen origin plus a GET with that Origin, and explains by the Fetch standard’s rules exactly which header blocked it.
• Currency Converter — Converts between about thirty currencies at the ECB’s daily reference rates, crossed through the euro, or at a rate you type in.
• Disposable Email — Gives you a throwaway inbox that receives mail for a limited time, with attachments viewable in place.
• DNS Lookup — Queries A, AAAA, CNAME, MX, TXT, NS, SOA, SRV, CAA and PTR records over DoH, with TTL and the DNSSEC bit shown, from Cloudflare or Google.
• DNS Propagation Check — Queries the same record from public DoH resolvers — Google, Cloudflare, Quad9, OpenDNS, AdGuard, NextDNS, Mullvad, DNS.SB, AliDNS — and shows which still hold the old answer.
• HTTP Header Inspector — Fetches a URL and shows the full response headers, redirect chain, timings and compression used.
• HTTP Request Builder — Composes and sends a GET/POST/PUT/PATCH/DELETE/HEAD request with custom headers and a body, and shows the status, headers, body and timing — without ever forwarding cookies or Authorization.
• IP Address Info — Shows your public IP or any address with its reverse name, ASN, announcing network, prefix and registry country from Team Cymru’s DNS data — no city-level geolocation.
• Link Preview Debugger — Reads Open Graph and Twitter card tags from a URL and renders how the link will look when shared.
• Mail Deliverability Check — Checks a domain’s MX, SPF, DKIM and DMARC records together and explains why mail would be rejected.
• Port Reachability Check — Tests whether a single TCP port on a host you specify accepts connections, and reports the banner.
• Redirect Chain Tracer — Follows a shortened or tracking URL through every redirect and shows the final destination.
• robots.txt & Sitemap Checker — Fetches robots.txt and the sitemap, tests whether a URL is crawlable and validates the sitemap format.
• Security Header Scan — Grades a site’s HSTS, CSP, frame, referrer and permissions headers and shows what to add.
• Sent vs Delivered Comparison — Send a draft to a disposable address from your own account and see what the sending path rewrote — links wrapped in redirects, dropped style blocks, added beacons, the encoding used.
• SSL Certificate Checker — Connects to a host, shows the served chain, expiry, protocol and cipher support, and flags chain gaps.
• WHOIS Lookup — Shows domain registration, registrar, nameservers and expiry, plus RDAP data where it exists.

These need a network peer to do their job at all: you cannot resolve a domain name or receive an email without talking to someone. What you type goes to our server, which asks the question and hands the answer back.

Tools that call the server for one step

• Bookmark Cleaner — Opens a browser bookmark export, finds duplicates, empty folders and favicon bloat, and writes a cleaned file back. Dead-link checking is not possible in a browser and is not claimed.
• ID Photo Maker — Crops a portrait to the ID and passport sizes of Korea, Japan, China, Spain, Mexico and the US visa, swaps the background and lays out a print sheet.
• Image Upscaler — Enlarges 2× or 4× with a directional interpolator that keeps diagonal edges sharp, with no model to download.
• JPEG Artifact Cleaner — Smooths the 8×8 blocking and ringing left by heavy JPEG compression or repeated re-saving.
• My Connection Info — Shows your public IP, its network and everything this tab reveals — browser, screen, language, time zone, connection — and names what a website genuinely cannot see, starting with your MAC address.
• Photo Denoiser — Removes sensor grain from high-ISO photos while keeping edges, with a strength slider.
• Self-Destructing Note — Encrypts a note in the browser and gives you a one-time link that destroys the note after it is read.
• Subresource Integrity Hash — Computes the Subresource Integrity attribute (sha256/384/512) for a script or stylesheet you paste or drop in.
• Suspicious URL Check — Inspects a link’s shape before you open it — lookalike characters, IP-literal hosts, @ tricks, deep subdomains, odd ports, shorteners — and on request traces its redirects and looks up the domain’s registration date. No reputation database.

These do their work in the browser tab. Where one of them calls our server it is for a single step the tab cannot do on its own — looking up your own address, holding an encrypted note until somebody reads it, following a link to see where it lands — and never to run the tool over your file.

Tools that are catalogued and not yet built are in neither list. They will appear the day they run.

What those tools keep

Two of them keep something on purpose. The disposable inbox is described below. The self-destructing note holds text your browser encrypted before it was sent — we hold the ciphertext and never the key — until it is read once or the lifetime you chose runs out, which is between an hour and a week.

The rest are asked a question and answer it. Nothing in this application writes your question to a database or to a log. Some of them cache the answer — a DNS record, a day of exchange rates — because the answer is not yours and is the same for everyone who asks.

What happens to a request outside this application is not ours to promise about: a host keeps access logs, and a lookup we forward to a public resolver arrives there with the name you asked about.

Disposable inboxes

Mail sent to a disposable address is held in memory rather than in a database, so a restart forgets all of it. It expires an hour after the last time you looked at it, and never later than a day after the address was first used. An expired message stops being readable at that moment, whether or not the cleanup job has run yet: every read checks the clock, and the sweeper only reclaims the memory afterwards.

The address is the only key. Anyone who asks for the same address gets the same inbox and can read what is in it — so do not use a disposable inbox for anything you would mind a stranger reading, and never for password resets on an account that matters.

The parts where you hand us something

Two parts of the site are not tools and do not work like one. The reference library keeps the pictures you upload; it strips their metadata on the way in, and other visitors see one only if you mark it public. Love Court sends what you write to a language model, which runs on somebody else’s computer; your browser removes the obvious identifiers first and shows you exactly what will be sent before it goes. Both pages say all of this before you commit to anything. And the person running this server can read what is stored on it, which is true of every service and is worth writing down rather than implying.

Analytics

There is none. No measurement script, no tag manager, no third-party beacon: the same network panel that shows you a tool not uploading your file will show you nothing being reported about your visit. The cookies this site sets are the ones it needs to work — the language you chose, a sign-in session if you made an account, and a ballot token if you vote in the court. Your theme and your tool settings are kept in your browser and never reach us.

Advertising

This site is free and will carry advertising. It carries none today. When it does, it will never be inside a tool’s working area or its results, and never an interstitial in front of a tool you came here to use.

What is already paid for is the price-tracking section: some links there earn a commission if you buy through them. Every one of those links carries a badge, and a notice sits above the first price on the page, because a paid link that does not say so is the whole thing that rule exists to prevent.

Your files are not shared with advertisers. For the tools that is a fact about where the file is rather than a policy — it never left your tab. For the two parts above, where you did hand us something, it is a policy: what you upload is not sold, rented or passed to an advertiser.
