Convert video clips to animated GIFs with intelligent optimization and size control.
Extract MP3 audio from YouTube videos for offline listening and lightweight sharing.
Video Background Remover removes the background from your uploaded video by converting it into a short series of resized frames, running automatic subject extraction per frame, and re-encoding the result as a modern WEBM (VP9) video. Use the controls to set output FPS (frames per second), a maximum frame count to keep processing practical, and an output width that balances clarity with speed. For edge quality, you can choose an edge profile and optionally apply decontamination to reduce background color halos around fine details. When you enable the premium AI Assistant option, the backend uses Gemini-powered background removal for improved results on complex subjects like hair or moving silhouettes. The output is returned as a downloadable WEBM previewed directly in the browser.
Video Caption Generator lets you burn captions into an uploaded video by using an SRT timeline you provide. Upload your MP4 (or compatible video), paste or edit SRT text, then convert to a downloadable MP4 where the captions are rendered directly on the frames. The tool includes practical subtitle styling controls—font size, alignment (top/center/bottom), primary text color, outline thickness—and a start/end time window so you can caption only a portion of your clip. If you want help creating a starting timeline, the premium AI Assistant option generates an SRT structure from a transcript when you explicitly click “Analyze with AI.” Core conversion runs on the backend for reliability and performance, and the result previews in the browser for quick iteration.
Video Cropper is a simple, no-install utility that helps you crop an uploaded video to a specific aspect ratio and immediately download the result as an MP4 file. You select an aspect ratio preset (for example 16:9, 9:16, or 1:1), then the backend computes a centered crop rectangle from the input video’s dimensions and processes the full video using FFmpeg’s crop filter. The tool supports both manual cropping via an AI-suggested crop box and automatic center-cropping when no crop box is provided. An optional AI Assistant can generate a safer crop rectangle from a preview frame, but it only suggests values—your video is cropped only when you click the main “Crop video” button. A built-in Sample Input button loads a short MP4 so you can test the workflow right away. Output video is re-encoded to H.264 (MP4) for reliable playback across devices and platforms.
WEBM to MP4 converts WEBM videos into widely compatible MP4 output so users can share, upload, and play clips across more platforms and devices without codec issues. The workflow is designed for speed: upload a WEBM file, tune quality using CRF and encoding preset, and download a converted MP4 generated on the backend with FFmpeg. This addresses the most common pain point where WEBM files fail in messaging apps, older players, or editing workflows expecting MP4/H.264. A sample input option helps users test output behavior quickly before processing private files. For users unsure about encoding tradeoffs, an optional AI Assistant suggests CRF and preset values based on use-case goals such as smaller file size, faster conversion, or quality retention. All processing runs through explicit user actions and returns predictable, share-ready MP4 files.
WEBM to GIF converts short WEBM videos into animated GIF files optimized for messaging, social sharing, and lightweight preview embeds. You upload a WEBM clip, adjust frame rate and output width, and generate a downloadable GIF through backend FFmpeg processing. The conversion pipeline uses palette generation and palette application to improve color quality while controlling output size. This is especially useful when users need loopable animations that are easy to paste into chat tools, documentation, and issue reports where static screenshots are not enough. A sample input button is provided for quick testing, and an optional AI Assistant can suggest practical FPS and width settings based on your use case and clip duration. The tool focuses on the most common pain point: balancing GIF smoothness and file size without manual command-line tuning.
Video Stabilizer is designed to reduce visible camera shake in handheld or motion-heavy footage and produce a smoother final clip that is easier to watch. You upload a shaky video, choose a stabilization strength level, and export a stabilized MP4 processed on the backend with FFmpeg. The pipeline performs motion analysis and transform-based stabilization, then re-encodes output for broad playback compatibility. This solves a common user pain point where quick recordings from phones, action cameras, or walking captures look jittery and distract from the content. The interface includes a sample input workflow for instant testing, clear strength controls, and an optional AI Assistant that recommends a practical stabilization level based on your footage goal. Processing remains explicit and user-triggered, so you keep full control over when transformation runs and when files are exported.
Video Speed Changer is a practical utility for adjusting playback speed of uploaded videos while preserving synchronized audio for real-world use cases like lectures, tutorials, demos, and social clips. You upload a video, choose a speed multiplier from 0.25x to 4x, and export a new MP4 generated on the backend with FFmpeg. The processing pipeline applies a video timing transform and audio tempo correction so speech remains aligned after acceleration or slowdown. This solves a common editing pain point where users need to shorten long recordings for faster review or slow down fast action for clearer explanation without opening complex desktop editors. The tool also includes a sample input button for instant testing and an optional AI Assistant that suggests practical speed settings based on your goal, while requiring explicit user action before any AI analysis runs.
Video Screen Recorder is a browser-based utility for capturing your screen and exporting recordings in a platform-friendly format without installing desktop software. You can start recording any shared window, browser tab, or full display using native screen-capture permissions, pause/resume when needed, and stop to instantly preview the result. For compatibility across devices and upload targets, the tool provides a one-click backend conversion step that transcodes the recorded WebM stream into H.264 MP4 while preserving audio when available. A sample recording button lets users test the full flow before sharing live content. The interface is optimized for fast workflows: record, preview, optionally analyze naming/export tips with AI Assistant, convert, and download. This directly solves a common pain point for tutorials, bug reports, demos, and walkthroughs where users need simple screen capture plus reliable MP4 output in one web flow.
Video Resizer helps you quickly change the output dimensions of a video for social posts, website embeds, messaging apps, and lightweight uploads without editing software. You upload a video, choose output width and height, select a fit mode, and export a resized MP4. The backend processes files with FFmpeg and supports three resizing behaviors: contain (keeps full frame with letterboxing), cover (fills target frame by cropping overflow), and stretch (forces exact dimensions). The tool validates dimensions, handles common video formats, keeps audio when present, and returns a downloadable H.264 MP4 for broad device compatibility. A Sample Input button provides an instant test file so users can understand output behavior before uploading their own media. This focused flow solves the most common resizing pain point: converting one source clip into platform-ready dimensions in a single step.
Video Cutter is a focused web tool that trims one continuous segment from an uploaded video using start and end times in seconds. You upload a video file, optionally use the sample preset to quickly set a first segment, and then click Cut video to export a new MP4. The backend performs time-based trimming with FFmpeg, validates the trim range against the detected duration, and re-encodes the output as H.264 MP4 for dependable playback. If the input video contains audio, the tool keeps the audio stream and encodes it into AAC during export. An optional AI Assistant can suggest a likely segment by extracting preview frames and returning recommended start and end times with a short rationale; the AI only suggests and the video is cropped only when you click the main Cut video action.
Video Metadata Editor is a streamlined utility for fixing and updating common metadata tags inside a video file. Upload a video and the tool probes the container and video stream, then reads existing metadata such as title, artist/creator, genre, year/date, and a description-like comment. You can edit these fields directly in the browser, preview the detected file information, and then click Update metadata to export an updated MP4 that includes your new tag values. The backend writes metadata using FFmpeg in a deterministic, stateless request so processing is fast and the UI stays responsive. If direct stream remuxing is not possible, it falls back to a safe MP4 export path for compatibility. An optional AI Assistant can suggest consistent tag values using the filename and detected tags; AI only suggests and nothing is applied until you explicitly update metadata.
