Non-ASCII Remover: Remove, Replace, or Escape Text
The Non-ASCII Remover processes pasted text using one of three policies: remove non-ASCII characters, replace each with a character you choose, or escape them as \uXXXX. Enable “Convert accents first” to normalize accented characters with NFD and remove combining marks, so café becomes cafe before the selected policy runs. Review the result and copy it when it matches your needs.
The Non-ASCII Remover is a browser-based text tool for removing, replacing, or escaping non-ASCII characters. Use it to prepare text for workflows that need ASCII characters or to represent characters as escape sequences. Its three policies let you decide whether non-ASCII characters disappear, become a replacement character, or remain represented in the output.
You can choose to remove the characters, replace each one with a character of your choice, or escape them as \uXXXX. The optional “Convert accents first” setting runs before the selected policy: it uses NFD normalization and removes combining marks, turning a word such as café into cafe. This lets you handle accented letters separately from the tool’s policy for other non-ASCII characters.
ASCII is a limited character set, while Unicode includes characters beyond ASCII, such as accented letters. When text needs to fit an ASCII-focused workflow, converting or removing characters can be useful; escaping offers another way to represent them in the output. Choose the policy that suits the text’s destination and how you need those characters handled.
The Non-ASCII Remover runs entirely in your browser. Your input is processed on your device and is not uploaded, stored, or sent to a server. It works offline once the page has loaded, so you can use it without a connection. The tool is free and can help developers and DevOps engineers handle text without installing a local utility.
Step 1: Paste or drop your text into the tool. Start with the content you want to clean, whether it contains accented letters or other non-ASCII characters.
Step 2: Choose how to handle non-ASCII characters. You can remove them, replace each with a character of your choice, or escape them as \uXXXX.
Step 3: Decide whether to enable “Convert accents first.” When enabled, NFD normalization and removal of combining marks convert accents such as café to cafe before the selected policy is applied.
Step 4: Review the result. Check that the chosen policy produced the text you need before using it elsewhere.
Step 5: Copy the result. You can then paste the cleaned or escaped text into your development workflow.
Use case: Clean text for a workflow that accepts only ASCII characters. Remove or replace non-ASCII characters before moving the text into that workflow.
Use case: Prepare accented text for a system that needs simpler spellings. Enable “Convert accents first” to turn café into cafe before applying your selected policy.
Use case: Create escaped text for a configuration or code-related task. The escape policy represents non-ASCII characters as \uXXXX rather than removing or replacing them.
Use case: Compare different cleanup approaches while debugging text issues. Try removing, replacing, or escaping characters and review the results in the browser.
Use case: Handle a routine Non-ASCII Remover task without installing anything locally. Paste or drop the text, choose a policy, and copy the result.
Use case: Work on a machine where you do not want to install a local utility or submit internal text to a third-party service. The tool runs in your browser and processes the input on your device.
