About Remove Letters
Remove Letters is a text tool that runs in your browser. Strip all letters (a-z, A-Z) from text, keeping numbers and symbols. The page you are reading is the same workspace you will use to do the work: pick a file or paste your input, choose the options that matter to you, and the tool produces the result on your device.
The engine behind the page is standard browser APIs. It reads your file in-memory and writes the result back into the browser. For 0 MB and below the work usually completes in seconds; larger files mostly depend on how much spare RAM your device has.
Remove Letters is shaped around the recurring needs of two audiences: support agents standardising replies, who use it as a quick utility between bigger tools, and translators aligning bilingual passages, who use it as their primary way of getting the job done. Both groups get the same defaults and the same speed.
Because everything runs in the page, the tool scales the same way for one user or a million — there is no per-user backend cost. The page is static, the engine is the same JavaScript bundle for every visitor, and the work happens on the visitor's own device. That keeps the tool free and keeps it fast on the first interaction.
Remove Letters 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.
Once the engine finishes, the output is offered as an immediate download. There is no preview gate, no email-wall, and no "register to download" intermediary — the file is yours the moment it is ready.
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.
Once you have used Remove Letters, the natural next steps depend on what you are doing with the result. Common follow-ups include Remove Numbers, Remove Special Characters, and Find & Replace. These are surfaced on the page so you do not have to hunt the catalog manually.
The transformation in Remove Letters is deterministic — the same input plus the same options produces the same result every run. That predictability matters when the result has to match an upstream specification or be reproducible later.
Remove Letters is one example of a broader pattern: utility software increasingly works as single-page, client-side experiences. Every page in the catalog is shaped that way, which keeps each tool fast to load and easy to recommend in a single link.
Remove Letters 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.
If you want to get the most out of Remove Letters, three small habits help. Drag-and-drop is faster than the file picker once you get used to it. The keyboard shortcut for downloading the result is whatever your browser uses for "save link as," because the result is a normal download. And if you are working on a sensitive file, processing in an Incognito or Private window is a good extra layer — it leaves no trace in browser history when the tab closes.
For most failure modes, refreshing the page and re-running the job is enough — the engine has no persistent state to corrupt. If the same input fails twice in a row, the input itself is most likely the problem (a truncated file, an unexpected variant of the format, or a stream the engine does not recognise).
If Remove Letters solved your problem, sharing the page link with someone who has the same problem is the most useful thing you can do. The catalog grows mostly through word of mouth; visitors arriving through a recommendation tend to be the ones the tool serves best.
How it works
- 1Land on the Remove Letters page. The tool is ready to use the moment the page renders.
- 2Select the text file you want to process — drag-and-drop and the file picker both work.
- 3Tweak the controls if the defaults are not quite right for your input. The options are kept short and labelled in plain language.
- 4Trigger processing. standard browser APIs reads your input, applies the transformation, and writes the result back into the page.
- 5Grab the output as soon as the run completes. You can also copy the result instead of downloading if the next tool in your workflow accepts pasted input.
- 6Run additional jobs as needed. The same controls and defaults apply on every run.
Common use cases
- Count the words in a draft to check it fits a brief using Remove Letters.
- De-duplicate a list of email addresses pulled from a form export.
- Convert a column of names into a comma-separated list for a script.
- Encode user input safely before pasting it into HTML.
- Reformat a JSON blob copied from a log into something readable.
- Find and replace dozens of variants of a phrase in one pass.
- Generate a slug from a long article title.
- Strip messy formatting out of copy pasted from a PDF.
- Translate plain text into Markdown for a static-site post.
- Sort a list of items alphabetically before publishing it.
FAQ
Which letters are removed?
All ASCII letters a-z and A-Z are removed. Numbers, spaces, and symbols remain.
Does it remove accented letters?
No — only basic ASCII letters are removed. Accented characters like é stay. Use Remove Accents first if needed.
What is this useful for?
Extracting phone numbers, zip codes, or other numeric data embedded in text.
Is processing local?
Yes — your text never leaves your browser.
Can I copy the result?
Yes — click Copy to Clipboard to copy the cleaned text.
Is there a character limit?
Up to 100,000 characters.
Why did Remove Letters reject my input?
Failures usually fall into one of three buckets: the input is in an unsupported format, the input is over the size cap, or the input is structurally malformed (a truncated download, a partial export, or a stream the engine does not recognise). The first two are easy to confirm — check that your file is in a supported format and that it is below 0 MB. For the third, opening the file in its native viewer first is the fastest way to confirm the source is intact.
How do I know I am using the latest version of Remove Letters?
Remove Letters is updated whenever the underlying engine releases an improvement or a bug fix. Because the tool is delivered as a static page, every visit fetches the latest version automatically — there is no "version" to manage on your end. If a particular release ever changes default behaviour, the change is documented on Favtoo's changelog so you can confirm what shifted.
Can Remove Letters run inside a corporate firewall?
Remove Letters 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.
Is Remove Letters lossless?
Remove Letters 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.
How many times per day can I use Remove Letters?
Inputs are capped at 0 MB per file, which keeps memory usage stable across phones, tablets and older laptops. You can run Remove Letters as often as you need; every run produces a full-quality result.
Does Remove Letters support batch processing?
Remove Letters 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.
Does Remove Letters ask for any browser permissions?
Remove Letters only needs the standard web platform — file picker access for the inputs you choose to load, and optionally clipboard access if you copy the result rather than downloading it. There is no microphone, camera, geolocation or background-permission request, because none of those are needed for the work the tool does.
Does Remove Letters work with screen readers?
Remove Letters 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.
