IAM Policy Minifier

Some workflows need an IAM policy document as a single compact line rather than a nicely indented block — pasting into an AWS CLI --policy-document flag, embedding inside a Terraform heredoc string, or setting it as a Lambda/CI environment variable where multi-line values are awkward. IAM Policy Minifier takes a pasted policy document and strips every non-significant character of whitespace, producing the exact same JSON on a single line.

Like the companion Beautifier tool, minifying only requires valid JSON — it does not require the document to already be a structurally complete IAM policy. If the JSON parses but the shape looks incomplete (missing Version, no Statement, and similar) the tool still minifies it and shows a separate structural warning alongside the result, rather than blocking you from getting the compact output.

A size-reduction panel shows the original character count, the minified character count, and the percentage saved — useful context, though worth knowing that AWS itself measures policy size against its character-count quotas with whitespace already excluded, so minifying does not change how much of your size quota a policy consumes; it only changes how compact the text is to paste around.

• Minifies any pasted policy JSON to a single line.
• Size-reduction stats — original chars, minified chars, percent saved.
• Works on any valid JSON, not just structurally valid IAM policies — with a warning when the shape looks incomplete.
• Line/column JSON syntax errors when the text does not parse.
• One-click copy of the minified output.
• Sample policy to try instantly.
• 100% client-side — nothing is uploaded.

1. Paste policy JSON, or click the sample.
2. Click Minify.
3. Copy the single-line result with the copy button.
4. Check the size stats if you are curious how much whitespace was removed.

Example 1 — indented policy. A typical 12-line formatted policy becomes one line, with the character-count panel showing the whitespace removed.

Example 2 — already minified. Running an already single-line policy through the tool reports 0% saved — there is nothing left to strip.

Example 3 — broken JSON. A copy-paste missing a closing bracket reports a specific line/column syntax error instead of minifying.

• Produces a single-line policy ready to paste into a CLI flag, heredoc, or env var.
• No semantic change — whitespace only, output evaluates identically to the input.
• Shows exactly how much was saved, in characters and percent.
• Private — minifying runs entirely in your browser.
