Social Media Post Designer
Create WhatsApp, Instagram and LinkedIn posts from ready-made templates. Edit text, colours and photos, then download a PNG sized for each platform — 100% in your browser.
Your photo is used as the background on every template (with a colour overlay so text stays readable).
What is Social Media Post Designer?
Social Media Post Designer builds ready-to-post images for WhatsApp, Instagram and LinkedIn from visual templates. Pick a platform size, choose a layout (promo, quote, announcement, photo overlay, tip or corporate), edit your headline and CTA, then download a PNG sized for that network.
Correct dimensions matter because each platform crops differently: Instagram feed favourites include 1080×1080 and 1080×1350, Stories and WhatsApp Status use 1080×1920, and LinkedIn commonly uses landscape ~1200×627 or square 1200×1200. Starting from those presets avoids awkward letterboxing after you upload.
Design and export run entirely in your browser on an HTML5 canvas. Optional background photos stay on your device, and nothing is uploaded to ToolSink — useful when you need a quick branded graphic without opening a full design suite.

Important notes
- This exports an image file; it does not publish to Instagram, LinkedIn or WhatsApp for you.
- Keep important text away from extreme edges on Story/Status formats so UI chrome does not cover it.
- Platform size recommendations can change — double-check in the app if a crop looks unexpected.
Frequently asked questions
Which platforms are supported?
Instagram (square, 4:5 feed, Story), LinkedIn (landscape and square), and WhatsApp Status. Each preset exports at that size.
Can I use my own photo?
Yes. Upload an image for the Photo Overlay template; other templates keep solid or gradient backgrounds.
Is my design uploaded?
No. Rendering and PNG export happen locally in your browser.
Can I edit the post after download?
The download is a flat PNG. Keep the ToolSink tab open or recreate the design if you need another version.
How is this different from the caption or bio generators?
Those tools write text. Post Designer creates the visual image you attach to a post or status.
