How do I create an Instagram post mockup?

Select "Instagram" in the platform selector at the top of the editor. Upload your post image, enter a caption, set your username, and adjust the likes and comments count. Click Download to export the mockup as PNG.

Does the mockup show Instagram Stories or Reels?

Currently the tool generates standard square Instagram post mockups. Stories and Reels support, with the correct vertical 9:16 format, is planned for a future update.

Why is the Instagram image area square?

The standard Instagram feed post format is square (1:1 aspect ratio). The mockup accurately reflects this. Portrait (4:5) and landscape (1.91:1) format options are planned for a future release.

Can I show the Instagram username in bold in the caption?

Yes, automatically. The caption area renders your username in bold followed by your caption text, which is exactly how Instagram displays captions in its native interface.

Can I customise the likes and comments count?

Yes. In the Metrics section, enter any number for Likes and Comments. The mockup displays them in the correct format — for example, "1,234 likes" and "View all 42 comments".

Step-by-Step: Crafting an Instagram Post Mockup

Follow these steps to generate production-ready Instagram visuals:

Set Your Template: Pick Standard Post for standard feed layouts, Image Focus to highlight photography, or Minimal for clean editorial captures.
Profile Setup: Add your brand or personal account handle and upload an avatar to populate the header circle.
Upload Post Imagery: Upload your 1:1 image or graphic. The preview automatically adapts to fit standard Instagram aspect ratios.
Write Your Caption: Type your post caption. The preview automatically formats your username in bold ahead of your copy, accurately replicating Instagram's native caption flow.
Adjust Engagement & Timing: Customize likes count (e.g., "1,420 likes"), comments, and timestamp text (e.g., "3 HOURS AGO").
Backdrop & Export: Pick a background gradient or transparent stage, toggle soft shadows, and export a high-resolution PNG file.

Instagram Post Mockup Generator is executed locally within your client browser.Processing happens entirely on your local device — your text, images, profile details, and generated mockup output are never transmitted to a remote server host. Zero data packets leave your machine during the generation, preview, or export workflow. This architecture means your work remains fully private: suitable for confidential client briefs, NDA-protected campaigns, and sensitive brand assets.

Output Verification Required

Before applying generated mockup assets to live campaigns, client submissions, or published materials, manually audit all output fields: verify display name spelling, metric formatting precision (e.g., comma separators for large numbers), image aspect ratios, typography rendering at export scale, and colour contrast against your target background. Mockup outputs reflect the input data as provided — they do not auto-correct formatting or validate real-world accuracy.
