When you edit a Threads image post, the alt text you carefully added may disappear. This happens because the Threads editor does not preserve the alt text field during the edit operation. The app treats the edit as a new image upload rather than a modification of the existing metadata. This article explains why the alt text is lost and provides a reliable workaround to keep your images accessible.
The root cause is a bug in how Threads handles image metadata during post edits. Instead of retaining the alt text, the editor clears the field. This affects both the mobile app and the web version of Threads. You can restore the alt text by editing the post a second time or by using a manual re-entry method.
This guide covers the exact steps to recover lost alt text, a preventive approach for future posts, and related issues you may encounter when editing image posts.
Key Takeaways: Restoring Alt Text on Threads Image Posts
- Post editor bug: Alt text is erased when you edit any image post on Threads, both on mobile and web.
- Manual re-entry method: After editing, tap the image and select Edit Alt Text to re-enter the description.
- Preventive approach: Use a text caption to describe the image as a backup in case alt text is lost.
Why Threads Removes Alt Text During Image Edits
Threads uses the Instagram infrastructure for image hosting and metadata. When you edit a post, the app sends a new image version to the server. The alt text field is not part of the edit request payload, so the server receives an empty value. As a result, the original alt text is overwritten with nothing.
This behavior is consistent across all platforms: iOS, Android, and the web interface. The bug does not affect text-only posts or posts that contain only a video. It only applies to posts with one or more static images.
The bug has been reported to Meta support but no permanent fix has been released as of this writing. The workaround below is the only reliable way to restore alt text after an edit.
Steps to Restore Alt Text After Editing a Threads Image Post
Follow these steps to recover the alt text that was lost after you edited an image post. The process requires you to edit the post a second time and manually re-enter the description.
- Open the edited post
Go to your profile and tap the image post that lost its alt text. The post must be the one you edited previously. - Tap the three-dot menu
In the top-right corner of the post, tap the three-dot menu icon. A dropdown menu appears. - Select Edit
Tap Edit from the menu. The post editor opens with the current image and caption. - Tap the image
Tap the image inside the editor. A small Edit Alt Text link appears below the image or at the bottom of the screen depending on your device. - Tap Edit Alt Text
Tap the Edit Alt Text link. A text field opens where you can type the image description. - Re-enter the alt text
Type the same alt text you originally wrote. Keep it concise but descriptive. For example: A person wearing a blue hat smiles at the camera while holding a coffee cup. - Tap Done or Save
Tap Done on iOS or the checkmark on Android. Then tap Save at the top of the editor to confirm the edit.
If the Edit Alt Text Link Does Not Appear
On some versions of Threads, the Edit Alt Text link may not appear if you are editing a post that contains multiple images. In that case, close the editor and try the following alternative method.
- Delete the post and repost
Delete the edited post and create a new post with the same image and caption. Add the alt text during the initial upload. This is the only guaranteed way to preserve alt text for multi-image posts.
If Alt Text Still Disappears After the Workaround
Some users report that the workaround does not work every time. The alt text may disappear again if you edit the post a third time. In that case, use the following alternative approaches.
Alt Text Lost After a Second Edit
If you edit the same image post more than once, the alt text is erased each time. The only fix is to repeat the manual re-entry process every time you edit. To avoid this, make all desired edits in one session before saving.
Alt Text Not Saving on Multi-Image Posts
For posts that contain two or more images, the Edit Alt Text link may not appear at all. Threads does not support editing alt text on multi-image posts after the initial upload. The only workaround is to delete the post and repost with the correct alt text added from the start.
Screen Reader Users Cannot Confirm Alt Text
Threads does not provide a way to read the current alt text on a published post. Screen reader users cannot verify whether the alt text is present without editing the post. To check, open the post, tap the three-dot menu, and select Edit. Then tap the image to see if the Edit Alt Text link appears. If it does, the alt text is missing and needs to be re-entered.
Threads vs Instagram: Alt Text Handling Compared
| Item | Threads | |
|---|---|---|
| Alt text preserved during edit | No — alt text is erased | Yes — alt text is retained |
| Edit alt text after publish | Yes, but only for single-image posts | Yes, for all post types |
| Multi-image alt text editing | Not supported after publish | Supported after publish |
| Workaround reliability | Inconsistent for multi-image posts | Not needed |
Threads is built on Instagram’s infrastructure but does not inherit all of Instagram’s editing capabilities. The alt text bug is one of the key gaps. Until Meta fixes the issue, you must manually re-enter alt text after every edit or use the delete-and-repost method for multi-image posts.
To minimize the impact of this bug, always add alt text during the initial post creation. Make all edits in one session to avoid multiple re-entries. For critical accessibility needs, consider using a text caption that describes the image as a fallback. This ensures that even if the alt text is lost, the description remains visible in the post body.
