Threads post preview
See your post as a Threads reply chain with media, check every 500-character post, and download a PNG.
The post is empty.
Text is saved in this browser for 24 hours. Media must be added again.
Drafts and local media stay in this browser. No social account is needed.

How draft transfer works
SimplePost opens in a new tab. Sign up or log in, connect a social account, then explicitly import, review and schedule. Keep the same browser and device; saved text expires after 24 hours. Copy your text if you need to switch devices.
Only text and threads transfer; upload media again. DEV versions are excluded. Transfers allow up to 25 posts per version and 200,000 total text units. The trial allows 20 posts per thread. An existing composer draft asks for confirmation before replacement.
How to preview a Threads post
A Threads preview shows the chain the way readers scroll it: each post under the previous one with the connecting line, and carousels with swipe controls. Use it to check that every post stands on its own and that the break points feel natural.
Write the first post
Keep it under 500 characters; the preview updates as you type.
Add follow-ups and media
Add posts to build the chain, and images or videos for a carousel of up to 20 items.
Read it in order, then download
Switch between light and dark mode and save a PNG for review.
SimplePost recreates a Threads-style feed. It is not affiliated with Meta, and small differences can appear when Threads updates its interface.
