60fps Looping Video · No Watermarks · Free
Animated Code Screenshot Generator
Static images are great, but motion stops the scroll. KromaStudio lets you turn any code snippet or browser mockup into a buttery smooth 60fps looping video. Pick from 3D Tilt, Float, or Auto Scroll presets, and export directly to a .webm video in seconds. The rendering happens locally in your browser, which means it is 100% free with absolutely no watermarks.

Why Upgrade to Animated Code?
Platforms like X/Twitter and LinkedIn algorithmically favor video content over static images. A subtle floating animation or a dramatic 3D tilt makes your code stand out in a crowded feed.
- You want to post code on X, LinkedIn, or TikTok and need a looping video format instead of a static image.
- You tried screen-recording your editor, but the quality is low, the frame rate stutters, and the background is boring.
- You don't have time to use After Effects or Premiere Pro just to make a 5-second code animation.
- You're tired of paying monthly subscriptions to tools that lock video export behind a premium tier.
- You want an all-in-one studio that can export both a high-res static PNG and an animated .webm from the exact same layout.
Static Code Images vs KromaStudio Video
| Feature | Traditional Code Tools | KromaStudio |
|---|---|---|
| Video Export | Static PNG/SVG only. | 60fps looping .webm video. |
| Export Speed | Screen recording requires manual setup and cropping. | 1-click generation. |
| Cost | Animated code generators often charge $5-$20/month. | 100% Free. |
| Watermarks | Free video tiers usually slap a huge watermark on your code. | No watermarks. |

Core Differences
No After Effects Required
Creating smooth 3D tilts or floating animations used to require complex motion graphics software. It was overkill for a quick Twitter post.
KromaStudio handles the easing, keyframes, and timing automatically. Pick a preset, hit export, and you get a buttery smooth 60fps loop.
See how animation works →Client-Side Rendering
Video rendering is typically computationally expensive, which is why other tools send your code to a cloud server to render the video, charging you for 'server time'.
KromaStudio uses the Canvas API and MediaRecorder to render the video locally using your device's GPU. It's faster, private, and completely free.

Browser Mockup Generator
Drop a screenshot into macOS, Windows, or minimal browser chrome. Tweak padding, corners, shadows, and aspect ratio, then export a PNG ready for a launch post or README hero.

Social Content Generator
Tweet cards, LinkedIn posts, threads, carousels, metrics snapshots — pick a template, fill in author and accent color, export PNG or a looping .webm.

Animated Code Screenshots
Pick Float, 3D Tilt, or Auto Scroll, render a looping .webm at 2× resolution, and post it — no After Effects, no screen recording.

Theme Customization
15 Shiki themes, 12 gradient presets, or roll your own two-color gradient. Toggle line numbers, bump font size, add a headline for social.
Code Screenshot Generator →Privacy-First Client-Side Processing
Everything renders in your browser — nothing gets uploaded. KromaStudio is MIT open source on GitHub, same as Carbon, so you can self-host if you want full control.
Privacy policy →Fast Export Workflow
Paste code, pick a theme, download a sharp 2× PNG in seconds. Same canvas does static PNG and animated .webm — one workflow for docs, feeds, and launch threads.
How it works →Who Needs Animated Code?
Frontend Developers
Share component refactors, CSS tricks, and UI patterns with syntax-highlighted cards — then wrap app screenshots in browser frames for portfolio pieces.
Backend Developers
Post API handlers, database queries, and config snippets with syntax highlighting rendered in your browser. Export clean PNGs for internal docs or public blog posts.
Indie Hackers
Ship launch graphics, metrics cards, and product mockups from one free tool — no separate design subscription required for a polished build-in-public thread.
Startup Founders
Create announcement cards, before-after stories, and browser mockups for Product Hunt, LinkedIn, and investor updates — all from the same studio.
Technical Writers
Produce consistent code callouts for documentation and tutorials. Use the same theme across every article so readers recognize your brand instantly.
Developer Advocates
Turn conference snippets, sample repos, and tutorial code into share-ready visuals — static for blogs, animated for social reach.

Frequently Asked Questions
- What format does the animated code export in?
- KromaStudio exports videos in the .webm format. It is a highly optimized, web-friendly video format supported by Twitter/X, LinkedIn, and most modern social platforms.
- Why .webm and not .mp4 or .gif?
- .webm offers significantly better quality and file size compared to .gif, while remaining natively supported by modern browser rendering APIs. MP4 encoding in the browser requires heavy WebAssembly packages, which would slow down the tool.
- Are the animations seamless loops?
- Yes! Presets like Float and Auto Scroll are mathematically calculated to loop seamlessly. They look great when uploaded to platforms that auto-replay short videos.
- Do I have to pay to remove the watermark on videos?
- No. KromaStudio never adds watermarks to your exports, whether they are static PNGs or animated videos.
- Will this work on Safari?
- Safari has limited support for the MediaRecorder API needed to export .webm videos. For the best experience and smoothest 60fps recording, we strongly recommend using Google Chrome, Edge, or Arc.
