Everything you need to edit videos quickly
A clean, Final Cut–style workspace: media library on the left, viewer in the middle, inspector on the right and a multi-layer timeline below.
Trim, split & rearrange
Drag clip edges to trim, press S to split at the playhead or use the blade tool (B). Drag to reorder; gaps on the Main track close automatically (ripple editing).
Unlimited layers
Stack video, photos, titles and audio on as many tracks as you like. Upper layers draw on top for overlays and picture-in-picture; sound from every layer is mixed together.
Music & audio mixing
Add background music, voice-over or sound effects. Set volume up to 200 %, fade in and out, mute clips or whole tracks, and detach audio from a video into its own track.
Picture-in-picture & transform
One-click PiP corners and split-screen halves, or set scale, position, rotation, flip and opacity yourself. Choose fit, fill or stretch for each clip.
Transitions
Cross dissolve, dip to black, wipe, slide and zoom with adjustable duration. On the Main track clips overlap for a true cross-fade of picture and sound.
Titles & captions
Title, lower third, subtitle, big bold, typewriter and banner presets. Change font, size, color, alignment, position, background box and shadow, with fade, slide, pop or typewriter animation.
Color looks & effects
Nine one-click looks — Vivid, Warm, Cool, B&W, Noir, Sepia, Faded, Dramatic, Dream — plus brightness, contrast, saturation, hue, sepia, black & white and blur controls.
Speed control
Slow motion and fast forward from 0.1× to 8× with quick presets (¼×, ½×, 1.5×, 2×, 4×). The timeline updates the clip length instantly.
Photos & solid colors
Mix still images into your video with any duration, or add solid-color clips as backgrounds and spacers.
Fast, precise editing
Snapping, frame-accurate stepping, jump between edit points, J/K/L shuttle, duplicate, nudge, unlimited undo/redo and right-click menus on every clip and track.
Autosave & local cache
Your project and imported media are saved in your browser automatically. Close the tab and come back later — everything is restored. Clear the cache anytime.
Layers that work the way you think
The timeline is generic: any track can hold video, audio, photos or titles.
- Main track (magnetic) — clips snap together with no gaps, like a primary storyline. Deleting or trimming a clip ripples everything after it.
- Free layers — place clips anywhere in time for overlays, logos, picture-in-picture, b-roll, titles and music.
- Per-track controls — hide pictures, mute sound, lock against edits, rename, reorder or make any track magnetic.
- Drop to create — drag a clip or file below the last track to create a new layer instantly.
How to merge videos online in four steps
Import
Open the editor and drag your videos, music and photos onto the page (or click Import media). Nothing is uploaded — files are read directly from your disk.
Arrange
Clips are placed on the Main track in order. Drag to reorder, trim the edges and split with S. Drag clips up to a layer for overlays.
Enhance
Add music below, titles from the Titles tab, transitions from the Transitions tab and a color look from Effects. Fine-tune anything in the inspector.
Export
Click Export, choose format, resolution, frame rate and quality, then pick where to save. Your video renders on your device and is saved locally.

Private by design
Video Editor Pro uses your browser's built-in hardware video decoders and encoders (WebCodecs). Your footage is processed on your own device and never sent to a server — ideal for personal, client and confidential videos.
Fast on your hardware
Previews play in real time with GPU compositing, and exports use hardware-accelerated encoding where available — often faster than real time. No waiting in an upload queue.

Frequently asked questions
Is Video Editor Pro free?
Yes. Video Editor Pro is free to use with no sign-up and no watermark.
Are my videos uploaded to a server?
No. Decoding, editing, previewing and encoding all happen in your browser on your own device. Your files are never uploaded.
Is there a file size or length limit?
Video Editor Pro does not impose a limit. In Chrome and Edge the exported video is streamed straight to a file on your disk, so even very large exports work. The practical limit is your device's disk space and speed.
Which formats can I import?
Common video formats such as MP4, MOV, WebM and MKV; audio such as MP3, WAV, M4A/AAC, OGG/Opus and FLAC; and images such as JPG, PNG, WebP, GIF and AVIF. Support for specific codecs depends on your browser.
Which formats can I export?
MP4 (H.264 video with AAC audio) or WebM (VP9 video with Opus audio), from 480p up to 4K, at 24, 25, 30, 50 or 60 frames per second, with four quality levels.
Can I merge videos with different sizes or frame rates?
Yes. Every clip is fitted into the project frame (fit, fill or stretch) and re-timed to the project frame rate, so phone videos, screen recordings and camera footage can be combined in one project.
Will I lose my work if I close the tab?
No. The project autosaves and imported media is cached in your browser, so reopening Video Editor Pro restores your session. You can clear this local cache from Project settings.
Does it work on a phone?
The editor adapts to small screens, but a desktop or laptop browser gives the best experience for editing and the fastest exports.
Which browsers are supported?
Recent versions of Chrome and Edge on desktop give the best results and unlimited-size exports. Firefox and Safari work where WebCodecs is available; Video Editor Pro automatically picks the best video and audio codecs your browser can encode.
