Take complete control over your text styles. Style your captions and titles with outline strokes, customized drop shadow offsets, soft glows, dynamic background padding, and custom color gradients on the canvas.
Precision Keyframe Editor
Animate any property over time. Add keyframes to visual tracks to control custom motion paths, fade clip opacities gradually, animate scale zoom factors, or rotate graphics dynamically across the timeline.
Advanced Layer Spatial Transforms
Reposition and compose media assets visually. Scale clips up or down, crop visual boundaries, rotate tracks by specific degree angles, or mirror files horizontal and vertical using responsive drag handles.
Creative Color Grading & Filters
Perfect the mood of your footage. Fine-tune visual track exposures, contrast levels, saturation depths, highlight ranges, and shadow intensities using highly responsive color sliders in the inspector.
Granular Audio Mixing & Level Balancing
Master your soundtracks like an audio engineer. Set fade-in and fade-out durations on sound clips, adjust individual track volumes, mute noisy background tracks, and balance voiceovers against background music beds.
Zero-Upload Privacy Protection
Keep your media files 100% private. Because Klipworm decodes, composite, and exports files entirely inside your local browser container sandbox, your raw video captures never leave your machine and are never uploaded to servers.
Offline Workspace Resilience
Edit anywhere, anytime. Since visual transforms and timeline tracks run entirely locally using your device's CPU and GPU, you can continue cutting clips, typing subtitles, and arranging tracks even with no internet connection.
IndexedDB Local Project Autosaves
Draft confidently knowing your work is secure. Video, audio, and image assets persist inside your browser's secure IndexedDB memory pool, while timeline track layouts autosave to localStorage, protecting drafts from crashes.
Magnetic Timeline & Gap-Snapping
Arrange and adjust your tracks seamlessly without worrying about accidental blank segments. The magnetic timeline snapping feature automatically closes empty spaces when you delete or trim video tracks, letting you slide clips around fluidly while preserving perfect sequence pacing.
Timeline Marker Bookmarks & Annotations
Bookmark key visual cues, audio beats, and edit points across your project tracks. Place colored visual markers on the timeline ruler to synchronize sound transitions, add reference notes, or label visual milestones during editing.

Have questions about our Online Video Editor? Find the answers below.
Q.Does the video editor open as a separate workspace?
Yes. Click Get started to open the Klipworm project workspace at /editor.
Q.Why does Klipworm have a projects screen?
Projects make Klipworm more useful than one-shot tools. Users can return to drafts, keep timelines organized, and continue work later.
Q.Are videos processed on the server?
Never. Klipworm runs all rendering, compositing, and encoding processes locally inside your active browser tab, protecting data privacy and saving bandwidth.
Q.Which devices and web browsers are supported?
Klipworm is fully supported across all modern web browsers, including Apple Safari, Google Chrome, Mozilla Firefox, Microsoft Edge, and Brave, on desktop, laptop, and tablet devices for fluid hardware-accelerated editing.
Q.Is an active internet connection required to edit?
No. Since editing operations and GPU transforms are executed locally on your system, you can continue adjusting your timeline even if your internet connection drops.
Q.Is there an upload file size limit?
Since Klipworm works entirely locally within your browser sandbox, there are no artificial file upload caps. The only limits are your hardware storage capabilities.
