Using Find & Replace on really large documents
How Find & Replace handles giant pastes — when it stays fast and when it bogs down. Browser-based, free, no signup, runs entirely on your device.
Most texts you work with don't justify opening Word. Find & Replace is for the in-between cases — paste, transform, paste back. Browser-local, no signup, no character limits.
Use the tool: Find & Replace — Everything happens locally in your browser — your file never leaves your device.
Handling big text
Find & Replace handles documents up to several MB of plain text comfortably. Above that, the browser stops being the right shape — drop to a desktop editor. For most use cases (essays, articles, drafts, scripts), you're well within Find & Replace's working range.

Frequently asked questions
Does Find & Replace count characters with or without spaces?
Find & Replace shows both counts simultaneously, so you can use whichever your target requires.
Can Find & Replace handle non-English text?
Yes — it uses Unicode-standard rules that work for most major scripts.
Can I trust the count for assignment / SEO purposes?
Find & Replace matches the published Unicode standard. Cross-check against the tool of record (Word, your CMS) if that's what's being graded against.
Is there a length limit?
Practically, several MB of text. Beyond that the browser starts to lag.
