Find & Replace is a free online PaperStack tool for text utilities. Search a block of text and replace matches one by one or all at once — including with regular expressions.
Find & Replace works on pasted text in your browser. You can match case, whole words, or RegEx patterns, highlight hits, replace the first match or every match, and even clean line breaks. Nothing is uploaded, so drafts, emails, and customer lists stay on the device.
You can use it on a phone, tablet, or computer. There is no sign-up, and processing runs in your browser so files and text are not uploaded to PaperStack for storage.
How Find & Replace is useful
This is the everyday editor move: rename a product, fix a misspelling that appears 80 times, turn “colour” into “color”, or wipe empty lines from a PDF paste. Doing it in PaperStack means you do not paste confidential copy into a random web app, and you do not need Word open for a text-only job.
Typical reasons people open this tool:
- Finish a one-off job without installing desktop software
- Keep documents and copy on the device they already use
- Move faster than emailing a file to themselves or waiting on IT
- Pair it with other Text Utilities on PaperStack in the same sitting

How to use Find & Replace
- Paste or type your text into the editor.
- Enter a Find value and an optional Replace value. Use Find to highlight matches, then Replace first or Replace all.
- Turn on Case sensitive or Whole word if you need stricter matching.
- Open RegEx Options for pattern-based edits or to join/remove empty lines.
- Copy or download a .txt file when you are done.

Practical tips
- Test RegEx on a small sample first so you do not wipe a whole document.
- Whole word stops “cat” from changing “concatenate”.
- Use Text Cleaner if you mainly need spaces and line-break cleanup, not search.
- Keep an original copy of anything you cannot afford to lose.
Why use PaperStack for this
Many “free converters” ask you to upload a file to a server you do not control. PaperStack is built around browser-side processing: you open the page, do the work, and download or copy the result. That is the difference when the file is a payslip, a contract, a customer CSV, or a draft that is not public yet.
You also get a consistent layout across PDF, Word, image, CSV, and text tools, so the next job does not require learning a new app.
Frequently asked questions
Is Find & Replace free?
Yes. You can use it without creating an account or paying a subscription.
Are my files uploaded?
No. Processing runs locally in your browser. PaperStack does not need your file on a server to run the tool.
Does it work on mobile?
Yes. Use a modern mobile or desktop browser. Very large files are more comfortable on a laptop because they use more memory.
Can beginners use it?
Yes. Follow the steps above. If something looks wrong, keep the original file and try a milder setting (for example less compression).
