Instagram post preview
See your caption and media as an Instagram feed card, then download a PNG. Nothing leaves your browser.
The post is empty.
Instagram needs an image or video.
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.
Publish and schedule with SimplePost
Connect a social account, then write and schedule your posts. New accounts get 30 days free instead of 7, no card.
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 Instagram post
An Instagram post preview puts the caption, account identity and media into a single feed card. Use it to check whether the first line earns attention, the caption stays readable and the visual carries the message before anything reaches your audience.
Write the caption
Paste the final copy with its line breaks, mentions and hashtags.
Add the account and media
Set the account name, username and avatar, then attach the image or video for the post.
Review, then download
Check the feed card, switch the preview theme, and save a PNG for approval.
SimplePost recreates an Instagram-style feed card. It is not affiliated with Instagram, and cropping or interface details may change in the native app.
Instagram post preview FAQ
What should I review in an Instagram caption preview?
Check that the first line explains the image, the line breaks make the caption readable, and the media keeps important details visible. This is a feed-card preview, not a profile-grid or Story simulator. Verify the final crop and eligible media format before publishing.
How can I preview an Instagram post before posting?
Paste the caption into the editor, add the account identity and upload the planned media, then select Instagram. The feed-style preview updates as you edit so you can review the post before publishing.
Is the Instagram post preview free?
Yes. You can create and download Instagram post previews for free without registering or adding a payment method.
Does the tool support multiple images?
Yes. You can attach up to ten image or video files to a post and inspect how the media and caption work together in the preview.
Does SimplePost store my caption or images?
The tool does not upload captions or local media. Caption text is saved in this browser for 24 hours; clear it with Clear saved text. Media must be added again after leaving the page.
Is this an exact copy of the Instagram app?
It is a close feed-style approximation, not an official Instagram renderer. Instagram changes its interface periodically, so verify important cropping and publishing details in the native app.
