Find & replace text acrossevery YouTube description at once.
YouTube Studio's bulk edit only adds or removes text at the start or end of a description. Description Modifier finds, replaces, adds, or deletes any text anywhere — across your entire catalog in one run, with a line-by-line preview before anything ships. Full undo on the last 10 runs.
Also works in Edge, Brave, Arc, and Opera. No separate download needed.
YouTube Studio can't find-and-replace inside a description. We can.
Studio's built-in bulk edit only appends or removes text from the very top or bottom of your descriptions. If an expired affiliate link or an old sponsor URL sits in the middle of a 200-video catalog, Studio can't touch it without opening every video by hand. Description Modifier searches the full text of every description and replaces the exact string — wherever it lives.

Your back catalog is a revenue engine. Treat it like one.
Every video you've ever published is still earning — or quietly leaking money through dead links, expired codes, and stale CTAs. Description Modifier turns your library into something you actually operate.
Stop sending viewers to 404s.
Sweep expired affiliate URLs, shut-down sponsor pages, and broken merch links out of every description in one pass.
Black Friday across 300 videos by lunch.
Push a seasonal banner, a discount code, or a limited-time offer to your whole catalog — then pull it down the moment it ends.
A new course link in every relevant video.
Roll out a course launch, newsletter signup, or product drop everywhere it belongs — with a line-by-line preview before anything ships.

Description Modifier lets you save reusable snippets — sponsor disclaimers, affiliate disclosures, merch links, seasonal banners, CTAs — as blocks. Insert a block at the top, bottom, or into any find-and-replace field with one click.
- Save sponsor blurbs, affiliate links, and disclaimers as reusable blocks.
- Insert blocks at the top or bottom of every description in scope.
- Drop blocks into Find, Replace, or Delete fields for bulk swaps.
- Blocks are stored in the extension, ready for every future run.
Never forget the edit you promised yourself you'd make.
Description Modifier has a built-in notes panel right inside the extension. Jot down reminders like “Delete the Squarespace promo on Jan 15” or “Swap spring merch to summer drop” so your next bulk edit is already planned when you open the popup.
- Store quick reminders inside the extension — no separate app needed.
- Link notes to future edits so you never lose track of a pending change.
- Notes stay on your device, private and ready every time you open Description Modifier.
- Turn a reminder into a find-and-replace run in seconds.
One wrong edit doesn't have to mean 300 manual fixes.
Every time you run a bulk edit, Description Modifier saves a snapshot of the original descriptions on your device. If something doesn't look right, open the undo history and restore every video in that batch back to exactly what it was — in one click.
- Automatic snapshots before every bulk edit run.
- Restore the last 10 batches with one click.
- Reverts every video in a batch to its original description.
- Snapshots stay on your device — private and under your control.

How do I change all my YouTube descriptions at once?
Install the Description Modifier Chrome extension, sign in with Google, connect your channel, and select the videos to update. Enter the text to find, enter the replacement, review the line-by-line preview, type CONFIRM, and the extension edits every selected description through the YouTube Data API — your whole catalog in one run.
Does changing a YouTube description affect views?
Editing a description does not reset watch time, likes, or comments, and description changes don't directly re-rank established videos. Keeping descriptions current with working links and relevant keywords can improve click-through from search and help viewers find the right resources — which supports long-term growth.
Can you bulk edit YouTube descriptions in YouTube Studio?
YouTube Studio's built-in bulk edit only adds or removes text at the very start or end of a description. It cannot find-and-replace a specific link or block of text in the middle. Description Modifier is built specifically for true find-and-replace anywhere inside the description body — across every video at once.
How do I remove an expired affiliate link from all my videos?
Paste the expired URL into the Find field, leave Replace blank (or enter the new URL), select the affected videos, and run the edit. Description Modifier searches the full text of every selected description, removes or swaps the exact link wherever it appears, and collapses the leftover blank line — all with a preview before anything ships.
