Quick Answer
A social post image maker turns a block of text into a finished, shareable image card — the kind people usually build by screenshotting an app. Type your post, set the author, date, and stats, pick a style (tweet light or dark, quote, LinkedIn, or terminal), and this free generator draws it on an HTML canvas in your browser with six accent themes, auto-fitting text, and editable metrics. Export a watermark-free PNG at 2× resolution or copy it to your clipboard — no account, and nothing you type leaves your device.
How It Works
Pick a card style and size — tweet light or dark, quote, LinkedIn, or terminal, at 1200 × 675, 1080 × 1080, or 1600 × 900
Type the post and set the author name, @handle, and date — in tweet styles a 280-character counter keeps lengths honest
Upload an avatar if you want one (cropped and stored at 256 px in your browser), edit the reply, repost, like, and view counts, and add a quote or headline line
Choose an accent theme and toggle rounded corners — the preview redraws as you type, and long posts auto-shrink to fit instead of overflowing
Download the watermark-free PNG at 2× resolution (up to 3200 × 1800) or copy it straight to your clipboard
Key Facts
- Five card styles — tweet light, tweet dark, quote, LinkedIn, and terminal — all drawn locally on canvas
- Six accent themes plus a rounded-corners toggle; every export is watermark-free
- Three sizes (1200 × 675, 1080 × 1080, 1600 × 900) exported as 2× PNG, up to 3200 × 1800
- Text auto-fits: word-wrap by measured width, then shrink-to-fit down to a 20 px minimum at 1.35 line height
- Editable replies, reposts, likes, and views, formatted compactly (for example “12K views”)
- Optional avatar upload, downscaled to 256 px in your browser — initials are drawn when no avatar is set
- Copy the PNG straight to the clipboard where the browser supports it, or download the file
- Form state is saved in this browser (localStorage) — no account, and nothing is uploaded
Frequently Asked Questions
How does the auto-fit text work?
The card measures your text with the actual canvas font, wraps it word by word against the card width (breaking only words wider than the card itself, code-point safe so emoji are never split), and steps the font size down in 2 px increments until the whole block fits its region — never below 20 px, with a 1.35 line height. In the rare case a post still overflows at 20 px, the visible lines are kept and the last one ends with a single ellipsis character.
Is this post image maker free?
Yes — free with no account, no trial, and no watermarks on any export. Image-automation services built for teams (for example Bannerbear, from $49/month) charge a subscription for generated social images; this tool draws every card in your browser at no cost, with a one-click sample post so you can see a finished card before typing anything.
Is my content private?
Yes. The card is drawn with the HTML canvas API entirely in your browser — the text, author, avatar, and stats are never uploaded, logged, or sent anywhere. The only persistence is your own browser’s localStorage (key pwt.post-image-maker.v1) so the form survives a refresh, and you can wipe it anytime with Clear card. After the page loads, the tool works offline.
Why are there no platform logos or verified badges on the cards?
The cards are a clean-room design: they use plain text labels like “12 replies · 45 reposts” instead of X/LinkedIn icons, logos, or verification marks, which are trademarks of those platforms. That keeps the images entirely yours to publish, while the layout, fonts, and accent themes still read as a social post at a glance.
What sizes and formats can I export?
PNG only, from three card sizes — 1200 × 675 (16:9), 1080 × 1080 (square), and 1600 × 900 (16:9). Every download renders at 2× resolution (2400 × 1350, 2160 × 2160, or 3200 × 1800) so text stays crisp when the image is viewed full-size. Avatars are downscaled to 256 px on upload to keep saved state small, and rounded corners can be toggled off for a square-edged card.
Can I copy the image instead of downloading it?
Yes, in browsers that support writing images to the clipboard (Chrome, Edge, and Safari do). Copy image renders the same 2× card and places the PNG on your clipboard for pasting into slides, docs, or a composer. Where the API is missing (some Firefox versions), the button is disabled and Download PNG works the same way.
