What this tool does
Create Twitter/X summary_large_image and common Open Graph share images. Set title, subtitle, footer, optional local logo, solid/gradient backgrounds and accent color, then download PNG. Everything is Canvas in your browser.
How to use
- Pick a size: Twitter/X 1200×675, OG 1200×630, or square 1080×1080.
- Fill title and description; optionally add a logo and tune colors.
- Download PNG when the live preview looks right.
FAQ
Are images uploaded?
No. Logos are read locally via FileReader; drawing and export stay in the browser.
Does this set my meta tags?
No — it only makes the image file. You still point twitter:image / og:image at a hosted URL.
Why 1200×675 and 1200×630?
1200×675 matches common X large-card proportions; 1200×630 is a long-standing OG default. Choose what your platform preview prefers.
Open-source notes?
This is an original slim local Canvas tool for AppShotMaker (not a full clone of a third-party Next app). Approach inspired by common open-source OG generators. No AGPL dependencies.
