About List Randomizer
List Randomizer is a single-page tool for the common text processing task it is named after. Randomly shuffle a list of items into a new order for raffles, games, or sampling. The interface keeps the input on one side, the configurable options in the middle, and the result on the other side. Most jobs start and finish without any scrolling.
List Randomizer sees the most use from editors comparing manuscript drafts and writers cleaning copy before publishing, but the design is intentionally generic enough that you do not need a specialist background to get a good result. The defaults aim at the most common case so a first-time user can get the right output without changing any settings.
List Randomizer works well as a bookmarked utility you reach for when you need it. The first visit shows you what the tool does; the second is when you realise it is a low-friction option for the task and worth keeping in your tab list.
List Randomizer runs on standard browser APIs — an open-source, well-audited engine that performs the text processing natively in the browser. It accepts the formats listed in the upload area and produces output that opens in any standard text viewer. Per-run input is capped at 0 MB.
The browser sandbox isolates the page's JavaScript from the rest of the system, the same way it isolates every other tab you have open. List Randomizer works inside that sandbox: it reads the file you give it, processes it with standard browser APIs, and writes the result back. Nothing leaves the page's memory unless you choose to download or copy it.
Once you have used List Randomizer, the natural next steps depend on what you are doing with the result. Common follow-ups include List Sorter, Random Name Generator, and List Deduplicator. These are surfaced on the page so you do not have to hunt the catalog manually.
The 0 MB ceiling on input size is the only fixed limit. Output files are produced in standard formats that every common viewer recognises, and the tool runs the same way regardless of how many times you have used it during the session.
List Randomizer is honest about scope: it handles a single, well-defined text processing step. Specialist edge-case work — uncommon formats, very large inputs, or pipelines that need scripting — is what dedicated desktop apps are for. This page handles the common case quickly.
Output handling is intentionally boring: List Randomizer produces a single output file and triggers your browser's standard "save" behaviour. If you have a default download folder configured, that is where it will land. There is no Favtoo-side history of jobs you have run.
From a product perspective, List Randomizer is one of the simplest possible expressions of "do one thing well." The catalog contains dozens of related tools that each handle a slightly different text processing task, and every one is a separate page rather than a tab inside a larger app. That separation keeps each tool fast to load and easy to bookmark.
List Randomizer is built around the moment of need: a focused page you open when you have a specific task, complete the task, and close. The catalog contains many adjacent tools so the same model serves the surrounding parts of a typical text processing workflow.
Tips from users who reach for List Randomizer regularly: process one input first to confirm the settings produce what you expect before committing to a batch; treat the page as the working surface and avoid leaving large jobs running in a backgrounded tab where the browser may throttle JavaScript; and if a particular file fails, check whether the source is intact by opening it in its native viewer — most "tool errors" are actually input errors.
If the result is not what you expected, the most common causes are easy to check. Confirm the input is under the 0 MB ceiling — files just above the cap fail silently because the engine refuses to allocate the buffer. Confirm the input is one of the supported formats. And if the page itself feels slow, try closing other heavy tabs to free up memory; the engine runs in your browser, so it competes for the same resources as everything else open.
That is the whole tool. Use List Randomizer for as long as it stays useful to you, and if it does, the catalog has many more tools built the same way. Each applies the same single-purpose discipline, so the way you used this page transfers to the next one you try.
How it works
- 1Open List Randomizer in your browser. The page loads quickly and the tool is ready to use the moment it becomes interactive.
- 2Add your text input by dropping it onto the page or browsing for it.
- 3Tweak the controls if the defaults are not quite right for your input. The options are kept short and labelled in plain language.
- 4Click to start the job. The engine (standard browser APIs) processes the input in the page; you can watch the progress indicator until it completes.
- 5Download the result. The file is generated in your browser and saved through your normal download flow.
- 6Repeat the process for additional inputs whenever you need to. The page stays loaded, so subsequent runs are quick.
Common use cases
- Re-case a title from ALL CAPS to Title Case using List Randomizer.

- Translate plain text into Markdown for a static-site post.
- Reformat a JSON blob copied from a log into something readable.
- Strip messy formatting out of copy pasted from a PDF.
- De-duplicate a list of email addresses pulled from a form export.
- Diff two drafts of a document side by side.
- Find and replace dozens of variants of a phrase in one pass.
FAQ
Is the shuffle truly random?
It uses a Fisher-Yates shuffle with a pseudo-random seed — sufficiently random for most purposes.
Can I shuffle again?
Yes — click process again to get a different random order each time.
Is this fair for raffles?
For casual raffles, yes. For legally binding draws, use a certified random number generator.
Does it preserve formatting?
Yes — each line is shuffled as-is without modifying its content.
Can I shuffle numbered lists?
Yes — paste your numbered items and they will be shuffled with their numbers intact.
Is my data safe?
Yes — all processing happens locally in your browser. Your text never leaves your device.
Are there any usage limits on List Randomizer?
Inputs are capped at 0 MB per file, which keeps memory usage stable across phones, tablets and older laptops. You can run List Randomizer as often as you need; every run produces a full-quality result.
How fast is List Randomizer?
Most jobs finish in seconds. Speed scales with input size and with how many CPU cycles your browser tab has available — the engine runs in your browser, so it shares resources with whatever else you have open. For inputs near the 0 MB ceiling, expect anywhere from a few seconds to roughly a minute on a typical laptop. Closing other heavy tabs noticeably speeds things up.
Does List Randomizer reduce quality of the result?
List Randomizer is built to preserve quality wherever the underlying text format allows it. Operations that are mathematically lossless (e.g. structural transformations, lossless re-encoding) round-trip with no perceptible change. Operations that involve a lossy codec inevitably introduce small artefacts at the byte level, but the defaults aim at the sweet spot where output looks or sounds the same to a normal viewer or listener while still being meaningfully smaller or faster than the input.
Can I self-host List Randomizer for my team?
List Randomizer is a static page running an open-source engine in your browser, so a typical corporate firewall does not get in the way as long as it allows JavaScript to load from Favtoo. For teams that need to host it themselves on an internal network, the underlying engine (standard browser APIs) is open-source and can be packaged into a private build with the same behaviour. Reach out via the Contact page if that is something you are exploring.
Does List Randomizer support batch processing?
List Randomizer processes one input at a time by design — it keeps memory usage predictable on lower-end devices and makes results easier to verify. To handle a folder, run the tool once per file; the page stays loaded between runs and remembers your last-used settings, so the second run is essentially instant.
Is it safe to use List Randomizer on confidential files?
Your file is processed inside your browser by standard browser APIs. The engine reads the file's bytes from your tab's memory, computes the result, and writes the result back into the tab. You can confirm what the page does by opening developer tools and watching the Network tab during a run — the requests you see are for the tool's static assets only.
Does List Randomizer match what professional tools produce?
List Randomizer is built on standard browser APIs, which is the same class of engine used by professional text processing pipelines. For deterministic operations, the output is byte-identical to what an equivalent CLI run would produce; for operations involving a codec or a model, the result is well within the range of what comparable tools generate. If you have a specific reference output you need to match, run a small test job first to confirm the configuration produces what you expect.
How accessible is the List Randomizer interface?
List Randomizer uses native HTML controls wherever possible, which means keyboard navigation, focus rings, and screen-reader labels work the way the platform expects. The drop zone accepts files via the keyboard-accessible file picker as well as drag-and-drop, and result downloads use standard browser download flows. If you spot an accessibility gap, Favtoo treats it as a bug worth fixing.
Is there a desktop version of List Randomizer?
No installation is needed. List Randomizer runs as a normal web page, with no browser extension, no native helper, and no separate desktop client to download. That is partly a privacy choice — extensions can request broad permissions, while a regular page is sandboxed by default — and partly a convenience one: you can use List Randomizer on any computer you have temporary access to without leaving anything installed on it.
