Whitespace Remover

The Whitespace Remover strips whitespace from text or Base64 — all of it, only line breaks, or collapsing runs to single spaces. It is for cleaning strings where stray whitespace causes problems.

Hidden whitespace breaks Base64 decoding and clutters text. Removing it locally with the right mode fixes the string instantly and privately.

1. Paste the text or Base64 you want to clean.
2. Choose a mode: remove all whitespace, only line breaks, or collapse runs.
3. The cleaned result updates.
4. Copy the tidied string.

• Pick the narrowest mode that fixes your specific problem.
