How to use: Edit video in the browser

Trim clips, arrange segments, and export video using your browser's built-in codecs — no upload, no watermark, processed entirely on your device.

  1. Load a video file from your device.
  2. Trim the parts you want and arrange segments on the timeline.
  3. Preview your cut in real time.
  4. Export; encoding runs locally, so duration and resolution determine how long it takes.

Tip: Browser video encoding is CPU-heavy — a laptop on power outperforms a phone for long exports.

How to use: Turn photos into an animated story or reel

Story Studio builds animated slideshows, social reels, stories and GIFs in your browser. You arrange slides, layer photos, text and shapes, animate each element independently with real start and end states, then export as video or GIF — nothing is uploaded.

  1. Start with your canvas: choose where the video will be posted and the shape and quality are set for you — or pick the aspect ratio and resolution yourself. Each resolution explains its trade-off, and “Help me choose” walks you through it.
  2. Use the tool rail down the left edge to switch panels — Uploads to bring in photos, Text and Elements to add layers, Slides to manage your story, Audio for a soundtrack.
  3. Click any element on the canvas to select it. Drag it to move, pull the corner handles to resize (hold Shift to keep its proportions), and use the round handle below it to rotate. Pink guides appear when it lines up with the center.
  4. With something selected, the toolbar above the canvas changes to match it — font, size, color and alignment for text; crop, fit and adjustments for photos; fill and border for shapes — plus opacity, duplicate and delete for anything.
  5. Use the filmstrip under the canvas to move between slides, read each one's duration, drag them into a new order, or press + to add another.
  6. Open Animate for any slide or layer to set separate START and END states — anchor, offset, zoom and opacity — then pick a transition between slides.
  7. Export as MP4/WebM video or an animated GIF; encoding runs on your device, so larger projects take longer.

Tip: Everything you need for a layer is in the toolbar directly above the canvas — the side inspector holds the deeper motion controls when you want them. For a classic Ken Burns effect, set start zoom to 100% and end zoom to about 115% with a slight offset.

How to use: Edit and fix subtitle files

Load SRT or VTT subtitles, edit text and timing, shift or stretch timestamps to fix sync, and export the corrected file.

  1. Load a subtitle file; entries appear with their timestamps.
  2. Edit any caption's text directly.
  3. Fix synchronization by shifting all timestamps, or stretching them when subtitles drift gradually.
  4. Export the corrected file in SRT or VTT format.

Tip: If subtitles start in sync and drift over time, you need a stretch (rate) fix, not a shift — the drift means the frame rates differ.

How to use: Turn video clips into GIFs

Convert a segment of any video into an animated GIF: pick the clip, set size and frame rate, and export — locally, with live preview.

  1. Load a video and scrub to find your moment.
  2. Set the start and end of the segment — short clips make the best GIFs.
  3. Choose dimensions and frame rate; smaller and slower means a lighter file.
  4. Generate the GIF, preview the loop, and download.

Tip: GIF files grow fast: two to four seconds at 480 pixels wide is the sweet spot for sharing.

Video Studio — every video tool in one private page

Trim, crop and convert video, build story clips, add and edit subtitles, and turn a clip into a GIF. Everything runs in your browser with no account and nothing uploaded, and your work in each tool is kept while you switch between them.

Video Editor

Join clips end to end, trim them, rotate and reframe the aspect ratio, lay text and a watermark over the picture, then export a real MP4 or WebM file. Nothing is uploaded.

Story Studio

Turn photos into polished animated stories, reels, social posts and GIFs: arrange slides, build split or overlay layouts, animate photo and text separately with real start and end states, and export MP4, WebM or GIF.

Subtitle Editor

Open, write and convert SRT and WebVTT subtitles: retime every cue at once, find and fix overlaps, validate the file and check each line against a live video preview — with full Persian and right-to-left text support.

Video to GIF Maker

Turn any clip into an animated GIF: pick the range, then set the frame rate, width and looping to balance smoothness against file size.

A real video editor, with zero uploads

This editor uses your browser's built-in WebCodecs engine — the same hardware-accelerated decoders and encoders the browser uses to play and record video. That means it can trim frame-accurately, join clips of different sizes, and export a genuine MP4 (H.264) or WebM (VP9) file, usually faster than real time, without your footage ever leaving your device. There are no accounts, no watermark forced onto your export, and no file-size games.

What it can do

Join any number of clips in order; trim each one on a filmstrip with frame previews; rotate in 90° steps; reframe between aspect ratios (make a vertical 9:16 cut of a landscape video, or square for feeds) with fill-crop or letterbox; adjust exposure, contrast, saturation and hue per clip; set per-clip volume or mute; burn in text overlays with timing, position and outline; stamp a semi-transparent watermark image in any corner; choose your exact codec (H.264, HEVC, AV1, VP9, VP8); and export at up to 4K with quality presets. Large exports stream directly to disk in supporting browsers instead of filling memory.

Good to know

HDR footage (common from recent phones) is tone-mapped through the browser canvas and exports as standard dynamic range, which can change its look. Surround audio is downmixed to stereo. Long, high-resolution exports are limited by your device's memory — a warning appears before very large jobs. Audio is re-encoded to AAC (MP4) or Opus (WebM) at 48 kHz stereo; if your browser can't encode audio, the editor tells you and offers a video-only export. Codec availability is detected on load and shown above the editor.

Media engine: Mediabunny (MPL-2.0), embedded unmodified.

A private social-story maker

Story Studio is designed for advocacy, education, community announcements, travel, personal memories and social campaigns. Photos, audio and project data stay in your browser unless you explicitly save or export them.

Multilingual by default

Text layers support automatic, left-to-right and right-to-left direction, including Persian, Arabic, Hebrew, Urdu and mixed-script writing. You may also load a font from your own device for the current session.

Subtitle timing and repair without uploading media

Subtitle Editor handles standard SRT and WebVTT cue files, provides a local video preview, identifies timing and reading-speed problems, and includes direction-aware text repair for multilingual captions.

Privacy

Your video stays on your device. The page itself still loads fonts and anonymous analytics from third-party services, so standard details like your IP address and page URL may be visible to them — as with any website.

Press 14 to switch tools. Each tool keeps its state while the studio stays open.
