Your feed preview
Cropping and caption truncation are approximations. This centered crop and estimated caption fold may differ from Instagram on your device. Your original file is unchanged.
Working sequence: check length in the caption counter, inspect the approximate feed preview here, then explore scheduling to publish it automatically.
From idea to feed in three steps
1. Choose a photo
Pick a local image and enter your display handle. No Instagram login needed.
2. Shape your story
Write your caption with emoji and line breaks. Expand it to review the full text.
3. Check the frame
Compare square and portrait crops, then copy your caption for your next post.
Before you post
Are my images private?
Yes. Images stay in this browser tab through local object URLs. This tool never uploads them or fetches your profile. Images and captions are not saved; refreshing clears the preview.
How accurate is the Instagram preview?
This is a feed mockup, not an official Instagram renderer. Centered cropping and caption truncation are approximations; fonts, spacing and the fold can vary by device and app version. Check the final post in Instagram.
Can I schedule or publish from this tool?
This free tool only previews a single image and copies captions. It does not publish, schedule or carry your draft into signup. Copy your caption before leaving, then explore the scheduler or create an account separately.
