CodeKitHubWhat Is This Tool?
Fake Tumblr Post Simulator recreates the real Tumblr post card layout — blog avatar and name, post text, an optional reblog attribution line, hashtag-style tags, and the combined likes-and-reblogs notes count — so you can export it as a shareable mockup image.
It must never be used to fabricate fraudulent evidence, harass or defame someone, or impersonate a real person's actual post — doing so may be illegal depending on your jurisdiction.
Everything is generated locally in your browser using the HTML Canvas API; nothing is ever uploaded to a server.
Why Use It?
- 100% local rendering — your content never touches a server.

- No account, no upload, no watermark — just type and download.

- Fill in your blog name, display name and avatar color (or upload a photo).
- Type your post content, then toggle the reblog chain line and image placeholder as needed.
- Add comma-separated tags and set the notes count.
- Watch the live preview update, then click "Download PNG" to save the image.

Responsible use
This generator exists to make it easy to create clearly fictional mockup images for humor, storytelling and design work. If you share an image made with this tool, consider adding context so viewers understand it is not a real post.
Frequently Asked Questions
Is it legal or ethical to use this tool?
The tool itself is legal to use for entertainment, mockups, presentations and design work. What is not legal or ethical is using the generated image to deceive someone. Please only use this for clearly fictional or illustrative purposes.
Does the tool upload my content anywhere?
No. Everything you type stays in your browser's memory and is drawn directly onto a canvas element with JavaScript. The PNG is generated and downloaded on your device — nothing is ever sent to a server.
What does "notes" mean on Tumblr?
On Tumblr, "notes" is the combined count of likes, reblogs and replies a post has received — it's shown as a single number at the bottom of every post, which this tool recreates.
Can I show a reblog chain?
Yes — toggle the reblog checkbox to add a short attribution line above the post text, mimicking how Tumblr shows that a post was reblogged from another blog.
