Offer posters for your Facebook shop, made in seconds.
Add a product photo, your prices and shop details — OfferPostio builds a clean, ready-to-post sale poster with the discount worked out for you. Download it as a PNG and post it straight to your page, group or profile.
Tip: after adding a photo, drag it on the poster to position it, and use the zoom slider to fill the frame.
Ready-made caption
A matching sales caption for the post — edit anything, then copy and paste it into Facebook.
How it works
Add the product
Upload a clear photo of the product, type its name, the regular price and the offer price. The discount percentage on the badge is calculated automatically.
Pick a size & theme
Square and portrait sizes suit Facebook feed posts; the tall story size fits stories and reel covers. Six colour themes cover everything from Eid sales to flash offers.
Download & post
Download the full-resolution PNG, copy the ready-made caption, and publish. Everything happens in your browser — no account, no watermark, no upload to a server.
Questions sellers ask
Which size should I choose for a Facebook post?
Square (1080 × 1080) is the safe all-rounder for feed posts and groups. Portrait (1080 × 1350) takes up more of the phone screen, so offers often get noticed more. Story (1080 × 1920) is for Facebook stories and reel covers.
Is OfferPostio really free?
Yes. Design and download as many posters as you like — there is no sign-up, no watermark and no payment.
Where does my product photo go?
Nowhere. The photo is read and drawn entirely inside your browser on your own device; it is never uploaded to a server.
Can I write the poster text in Bangla?
Yes — type Bangla in any field (product name, shop name, tagline) and it will appear on the poster using your device's Bangla font. The caption generator can also write the full sales caption in Bangla.
The photo doesn't fill the frame the way I want. What can I do?
Drag the photo directly on the preview to move it, and use the zoom slider to crop in closer. A landscape photo in a tall story poster will always need some cropping — zoom in on the product itself for the best result.
