Why Use Social-Media-Bildgenerator?
Canva and Adobe Express are powerful, but they require an account, charge for exports, and send your brand assets to their servers. Zeraku's Social Asset Generator runs entirely in your browser — paste your image, choose your platforms, download a ZIP. No login, no watermark, no monthly fee. Ideal for creators, small businesses, and marketers who need fast, private, one-click social exports.
Social Media Resizing Without Account or Upload
Canva and Adobe Express require an account and upload your brand assets to their servers. Zeraku resizes everything in your browser — instant, private, and free.

Beginner's Guide
Social Asset Generator automatically resizes one image into the exact dimensions needed for every social media platform — Twitter/X, Instagram (square, story, reel), LinkedIn, Facebook, and more. Instead of manually resizing your image multiple times, you upload it once and download all sizes in a single ZIP file. Great for launching a campaign, promoting an event, or keeping your social profiles looking polished without design software.
Technical Details
Built on HTML5 Canvas with a custom multi-layer rendering engine. Each platform preset stores its pixel dimensions and safe-zone margins; the engine reflows text and repositions layers automatically when switching formats. Image transforms (crop, scale, rotate) use the Canvas 2D API. Text rendering supports system fonts plus a curated set of Google Fonts loaded via FontFace API. Batch ZIP generation runs in a Web Worker using the JSZip library so the main thread — and the UI — stays responsive during export. All assets are generated client-side; nothing is sent to a server.
