Independent preview — not affiliated with Threads or Meta.

How it works

Fill in your display name, @handle and post text — the preview redraws as you type.
Toggle light/dark theme and mobile/desktop framing to check both reading contexts.
Export the exact preview as a PNG at 1x–3x, or copy the text with a character count.

What you can preview

Truly live preview

Every keystroke re-renders the card. No buttons, no refresh, no waiting.

Light & dark themes

Check contrast and emoji visibility on both Threads color schemes.

Mobile & desktop framing

See how the same post reads on a phone-sized card versus a wide layout.

Optional engagement stats

Add like, reply and repost numbers to preview a post that already has traction.

WYSIWYG export

The PNG export is generated from the same renderer as the preview — what you see is what downloads.

Private by design

Everything runs in your browser; uploaded avatars stay as local object URLs.

When to use it

Check line breaks and emoji placement before publishing a announcement.
Mock a post screenshot for a deck or client approval without faking it in design tools.
Test how a long post truncates on mobile before you hit publish.

Preview tips

This is an independent mockup, not the official Threads client — final rendering in the app may differ slightly.
Keep handle and display name realistic so spacing decisions hold in the real app.
Dark theme is the quickest way to spot low-contrast emoji and links.

FAQ

Is this the official Threads preview?

No. This is an independent mockup tool built by ThreadsDownloader.org. It simulates how a post looks so you can review it before publishing, but it is not affiliated with Meta or Threads.

Does the preview reflect the real Threads limit?

The live counter uses the same 500-character limit as the Threads composer, so you see truncation risk before publishing.

Can I add my own avatar?

Yes. Upload any image — it stays in your browser as a local object URL and is never sent to a server.

What format is the export?

PNG at 1x, 2x or 3x resolution, rendered by the same engine that draws the preview.

Does posting from here publish to Threads?

No. Nothing is published or transmitted — this tool only previews and exports an image.
