A social media post maker is a free online tool that designs platform-ready graphics, writes captions and generates hashtags in one place. This kit includes a post designer with exact Instagram, Facebook, LinkedIn and X sizes, a bulk mode for a week of posts, a caption studio and a hashtag generator, plus honest guidance for scheduling everything free with each platform’s native scheduler.
Design a week of social posts in minutes
Create perfectly-sized graphics for Instagram, Facebook, LinkedIn and X, write captions with our studio, generate hashtags - then schedule everything free with the native schedulers. Honest note up front: no static web page can auto-post to your accounts on a schedule by itself (that needs a server). This tool gives you unlimited bulk creation plus the real free scheduling workflow.

Caption preview
⚠️ Read this first - honest publishing limits
- This page can "publish now" where platforms allow browser-based API calls. It cannot auto-post on a daily schedule by itself - that needs a server or the platform's own scheduler (see the Scheduler Guide tab).
- Meta tokens expire. A pasted access token works until it expires (short-lived: hours; long-lived: ~60 days). Refreshing requires an app secret, which a static page can't hold safely - so paste a fresh token each session. Your token never leaves your browser except to Meta's API.
- X (Twitter): posting via API now requires a paid X API plan ($100+/month Basic). The free tier is read-only. That's why there's no X auto-post button here - it genuinely isn't possible for free.
- TikTok: posting via API needs an approved developer app (Content Posting API). Apply at TikTok for Developers; until approved, use the Scheduler Guide workflow.
Post to Facebook Page
Uses POST /{page-id}/photos on the Meta Graph API. Needs a Page token with pages_manage_posts.
Post to Instagram (Business/Creator)
Two-step: creates a media container, then publishes it. Needs a Business/Creator account linked to a Facebook Page.
API log
Real API responses appear here - successes and errors alike. Nothing is faked.
📅 The real "auto-post daily" workflow - 100% free
Since no free static tool can post on a schedule by itself, here's the workflow the pros actually use: design in bulk here → schedule free with each platform's native scheduler. Set it up once a week and your posts go out daily, hands-off.
Meta Business Suite Facebook + Instagram
- Go to business.facebook.com → log in → open Content.
- Click Create post → upload the designs you made here.
- Paste your caption + hashtags from the Caption Studio.
- Click the dropdown next to Publish → Schedule → pick date & time.
- Repeat for the week. Both Facebook and Instagram (Business/Creator) are covered - free, unlimited.
Pinterest native scheduler Pinterest
- You need a free Pinterest business account.
- Click Create → Create Pin, upload a design from this tool.
- Add title, description and destination link.
- Choose Publish at a later date → set your daily slot.
- Queue up to 30 days ahead. (Our Pinterest Pin Creator makes the pins in bulk.)
LinkedIn scheduling LinkedIn
- Start a post on LinkedIn (desktop) → attach your 1200×627 design.
- Click the clock icon at the bottom of the composer.
- Pick date & time → Schedule. Free and built-in.
- For X/TikTok without paid APIs: draft in bulk here, post manually, or use each app's drafts - still far faster than designing daily.
🗓️ Suggested weekly rhythm
Sunday (30 min): bulk-design 7 posts here → write 7 captions in Caption Studio → Monday–Friday: everything posts itself from the schedulers → Weekend: check what performed, repeat. Consistency beats intensity.
How to use the Social Media Kit in 5 steps
- Pick a platform size (Instagram, Story, LinkedIn or X).
- Add your title, subtitle and brand line, then style colors and font.
- Download the PNG, or use bulk mode for a week of posts.
- Write captions and generate hashtags for your niche.
- Schedule everything free with each platform’s native scheduler.
How can I create a week of social media posts for free?
List 7 post ideas as one line each, using the Title | Subtitle format. Pick your platform size and a template, then use bulk mode to generate all 7 designs at once. Write captions in the caption studio, generate hashtags for your niche, download everything, and queue the posts free with each platform’s native scheduler.
The scheduler guide then walks you through queueing each platform’s native free scheduler, because no static web page can auto-post on a schedule by itself.
What size should my Instagram and LinkedIn posts be?
Use 1080x1080 px for Instagram and Facebook feed posts, 1080x1920 px for Stories and Reels, 1200x627 px for LinkedIn posts, and 1200x675 px for X. The designer’s size presets apply these in one click, so your graphics always match each platform’s recommended dimensions.
Stories and Reels use 1080x1920, Pinterest pins use 1000x1500, and X posts use 1200x675. Picking the wrong size crops your message or shrinks your reach.
Frequently asked questions
Is this really free and unlimited?
Yes. Design as many posts as you want, generate unlimited hashtags, check unlimited captions. No account, no watermark, no caps - everything runs in your browser.
Can it auto-post to my accounts every day by itself?
Honestly, no - and neither can any other free static web page. Scheduled auto-posting needs a server or the platform's own scheduler. This tool gives you unlimited bulk creation plus step-by-step guides for the free native schedulers (Meta Business Suite, Pinterest, LinkedIn), which is the real workflow.
Why is there no X (Twitter) auto-post button?
X's API now requires a paid plan (around $100+/month) just to post. Their free tier is read-only, so free auto-posting to X isn't technically possible. We'd rather tell you that than fake a button.
Are my access tokens safe?
Tokens you paste are used only for the API call you trigger and are never stored on any server (this page has no server). For extra safety, generate tokens with the minimum permissions needed and never share them.
What image sizes should I use?
Instagram/Facebook feed: 1080×1080. Stories/Reels: 1080×1920. LinkedIn: 1200×627. X: 1200×675. Pinterest: 1000×1500 (use our Pinterest Pin Creator). All are one click in the designer.
Do my uploads leave my device?
No. Background images and designs stay in your browser until you choose to download or publish them. Nothing is uploaded to our servers - there are none.
