Free Post Image Generator (+ Guide)

What is a post image generator?

A post image generator is a tool that turns a social media post into an image: the words drawn as a card, with the author's name, photo and handle, in the size each platform wants.

This one reads the post from its link, so you never retype it. It draws 9 kinds of card, from a plain post card to a quote, a list, a thread or a carousel, in 8 sizes, and saves them as PNG, JPG or WebP, a carousel PDF or a typing video. It all happens in your browser.

Why post images work

A strong post dies when it stays on 1 platform. As an image it travels: an X post becomes an Instagram slide, a LinkedIn post becomes a pin, a thread becomes a carousel.

The card keeps your name and photo on the words. Wherever it's shared, people know whose idea it is, so every repost builds your name, not only the idea. It's how my own quotes work: each one downloads as a card with my name and photo.

And it beats a screenshot. A screenshot is blurry, carries the app's buttons, and comes in 1 size. A drawn card is sharp at full size, shows only the post, fits any platform, and lets you fix a typo first.

How to turn a post into an image

Paste several links, 1 per line, to make a conversation or a thread image, or to download 1 image per post in one go.

Then post it, or schedule it with the tools on my creator tools page.

Which links it reads

Each platform shares a different amount without a login, so here's exactly what you get from each:

Platform	What it fills in
X	Text, name, handle, photo, badge, likes and replies. Reposts you type in
LinkedIn	Full text, name, photo, likes, comments and date, for text and video posts
Substack	Notes: the text, name, photo and date. Posts: the title and subtitle
Threads	Text, name, handle and photo
Facebook	Name and the first 200 characters. You paste the rest and add the photo
Bluesky	Everything, counts included
Mastodon	Everything, counts included
Pinterest	The pin's words, the pinner and the pin's picture, as a card with its picture

Short links work too, like the lnkd.in link LinkedIn's Copy link to post gives you, and pin.it from Pinterest. The tool reads only the post you paste, under its own name, and keeps nothing. If a platform doesn't answer, paste the text and carry on.

9 kinds of card

A post doesn't have to look like a post. The same words can be a card, a quote, a headline or a carousel:

• Post card: the photo, name, badge and handle, the text, then the counts
• Quote: the words big, with a quote mark and the name under them
• Headline: 1 big line, for a hook
• Text only: just the words, with no name or photo
• List: a post's points as a numbered list
• With its picture: the post's own photo or link card under the text
• Conversation: a post and its reply, joined by a line
• Thread: several posts stacked the same way
• Carousel: slides with a cover, the body and a last slide to follow you

Each kind sizes its text to fill the card. A 1-line post comes out big, a long one stays readable, and no word is left alone on the last line.

Looks: 29 of them, or your own

The looks come in 6 families, in dark and light:

• Clean: black, dim, minimal, light and cream
• Brand gradients: blue and teal, blue to indigo, cyan, sunset, gold and red
• Editorial: serif dark, serif light and newspaper
• Paper and grids: paper, vintage paper, a vintage note, grid paper, a dot grid, a sticky note, a notebook page, a blueprint, a dark grid and a grainy gradient
• Photo: your words straight on a photo, under a dark or a light veil
• Glass: a frosted card over a gradient, or over a photo

For a photo, search the free photos from Pexels right in the tool, or upload your own. It starts with the words of your post, and Pick the best for me takes the photo with the calmest space behind the text, in the card's shape, and a veil that keeps the words readable.

Any look takes any of 6 fonts: Inter, the rounded Poppins, the editorial Playfair, the classic Garamond, Newsreader and a typewriter, in 4 weights. Text size has Small, Medium, Large and XL, and a slider in between.

Or pick My brand and set your own background, text and accent colors and font. Paste your DESIGN.md, or make one with my DESIGN.md generator, and it takes the colors from it.

Press Save this look to keep a look with its photo shape, badge, sizes and extras, and use it again in 1 press next time.

The verified badge takes each look's colors, with its check cut out, so on a dark card it reads as part of the card.

Which size for which platform

Pick as many sizes as you need and download them together as 1 zip:

Size	Pixels	Good for
Instagram 4:5	1080 × 1350	Instagram and Facebook feeds, where a tall image takes more room
LinkedIn 4:5	1200 × 1500	LinkedIn, the same shape with more pixels
Instagram tall 3:4	1080 × 1440	Instagram's profile grid, which shows posts as 3:4 tiles since January 2025
Square 1:1	1080 × 1080	Anywhere, X and Threads included
Story 9:16	1080 × 1920	Stories and Reels covers, with the top and bottom kept clear for the app's own buttons
Wide 16:9	1920 × 1080	YouTube, X and slides
Link preview 1.91:1	1200 × 628	The card under a shared link, on LinkedIn, X and Facebook
Pinterest 2:3	1000 × 1500	Pinterest

Instagram 4:5 is the feed size everyone knows. The grid trims a sliver off each side of it, while tall 3:4 fills the grid's tile with no crop. Post a 3:4 image from the Instagram app, though: scheduling tools publish through Meta's API, which takes 4:5 to 1.91:1 only (Meta).

A size that's too small for your text is grayed out, so a long post can't end up as a hard-to-read link preview. Tick Sharper (2x) for twice the pixels, for phones that show every one.

How to make a LinkedIn carousel from a thread

LinkedIn shows a PDF as a swipeable carousel. Here's how to make one from a thread or a long post:

A long post splits between paragraphs, and a long paragraph between sentences, never inside one. The last slide asks people to follow you. For Instagram, press Download slides for the same slides as images. Or open the pages made for each: my LinkedIn carousel generator and Instagram carousel generator.

Make a typing video of your post

Press Download typing video and the card comes out as an MP4 with your words typing out, a blinking cursor, then a pause on the whole post. It runs a few seconds for a short post and up to about 15 for a long one.

A moving post stops the scroll where a still one gets passed, and it works as a Reel, a Story or a video post on X and LinkedIn. It's made in your browser too, so nothing is uploaded. If your browser can't make video, the button doesn't show.

For a carousel, press Download animated slides: 1 MP4 per slide, each typing its own words, for an Instagram carousel, which mixes photos and videos. A LinkedIn carousel is a PDF, and a PDF can't move, so it stays still.

Download animated HTML gives you the card or the carousel as a web page that moves: the words type in and the slides slide, with arrows, swipe and full screen. It's for your website, a link or a talk. No platform takes HTML as a post, so post the images, the PDF or the video.

Design rules for a card that reads on a phone

Most people will see your image on a phone, about 390 points wide. Those few points decide whether they read it:

• Text at 32 pixels or more on a 1080 pixel image. Smaller reads smaller than the phone's own text. The tool warns you when it drops under
• Contrast of 4.5:1 or more between text and background, the WCAG line for readable text (W3C). The tool warns you when a look falls under it
• 1 idea per card. If it needs 2, make a carousel. A kind that can't hold your text, like a headline for a long post, is grayed out
• Short lines. A wide image keeps the text to a column in the middle

Alt text: what to write

Every platform lets you add alt text to an image, so people who use a screen reader hear what it says. For a post image, the best alt text is simply the post: who said it and the words.

The tool writes it for you under the preview. Copy it and paste it into the platform's alt text box when you post.

Turn 1 post into 5 formats

1 good post can travel. From the same words:

• A post card for X or Threads
• A quote at 4:5 for Instagram and LinkedIn
• A story at 9:16
• A carousel PDF for LinkedIn, if it's long enough
• A Pinterest pin at 2:3

Pick all 5 sizes, and download once. It's the easiest way to post every day without writing more, and here's why consistency is key.
