Video Tools

Mix music or narration with an existing soundtrack, or replace it, using MiniWebtool’s Add or Replace Audio in Video. The original video duration is retained: longer audio is trimmed, while shorter audio can play once or loop.

MiniWebtool’s Add Subtitles to Video (SRT Burn-in) permanently renders SRT or VTT captions into a video. Set font, size, color, outline, and position; browser-drawn text supports multilingual characters and emoji.

MiniWebtool’s Add Watermark to Video previews a text or logo watermark on your playing video before export. Keep it fixed, move it around the frame, or repeat it across the picture while retaining the original sound and resolution.

Create slow motion or a faster clip using MiniWebtool’s Adjust Video Speed. Choose a preset from 0.25x to 4x or specify a custom rate, then preview the result; audio tempo changes while pitch is preserved.

Prepare a clip using MiniWebtool’s Convert Video for Twitter (X). Browser-side conversion produces H.264/AAC MP4 output with selected frame sizing, a 30 or 60 fps cap, and a modeled 2-minute-20-second limit.

MiniWebtool’s Cut Video keeps a chosen segment or removes selected sections and joins the remainder. Preview the edits and create the cut video through on-device processing, with synchronized audio.

MiniWebtool’s Flip Video reverses a clip’s picture horizontally or vertically. Choose a mirror effect or upside-down view to produce a transformed video for editing, presentation, or correcting the intended orientation.

MiniWebtool’s FPS Converter changes a video’s frame rate to a selected frames-per-second value. Use it to standardize clips or meet a frame-rate requirement; changing FPS alone does not establish the amount of genuine motion detail captured.

An animated GIF can become an MP4 video with MiniWebtool’s GIF to MP4 Converter. Choose output quality and keep, resize, or scale the dimensions, then preview the converted video before downloading it.

MiniWebtool’s Horizontal to Vertical Video Converter reframes landscape footage for a 9:16 canvas. Use people tracking, blurred fill, or a solid background, inspect safe zones in preview, and export MP4 in the browser.

Repeat a video a chosen number of times using MiniWebtool’s Loop Video. Select the source and repetition count to create a longer sequence processed in your browser.

MiniWebtool’s Merge Videos combines selected clips into a single sequence. Arrange the files in the desired order before merging them in your browser, then download the resulting video.

MiniWebtool’s MP4 to GIF Converter turns a video into an animated image. Adjust the output dimensions and frame rate, preview the animation, and generate a GIF in your browser.

Scroll your script at your speaking pace with MiniWebtool’s Online Teleprompter. Read to the camera and record yourself in landscape or vertical video, or present full screen with mirror mode for glass teleprompter rigs.

An uploaded video becomes a set of candidate stills in MiniWebtool’s Random Video Thumbnail Generator. Choose how many random thumbnails to make, preview the video, and download individual images or a ZIP bundle.

Create a silent version of a video with MiniWebtool’s Remove Audio from Video. Select the file to remove its audio track through browser-side processing, then use the muted video output.

Reverse a short clip’s playback with MiniWebtool’s Reverse Video. Optional start and end times let you select a segment; processing runs in the browser and works best with clips under twenty seconds.

Correct a clip’s orientation with MiniWebtool’s Rotate Video. Choose a quarter-, half-, or three-quarter turn and process the rotation in your browser to produce the reoriented video.

MiniWebtool’s Video Bitrate Calculator allocates a target file-size budget between video and audio. Duration, resolution, frame rate, codec, and quality settings inform bitrate estimates and suggested encoder settings.

Reduce a video file’s size with MiniWebtool’s Video Compressor. Adjust quality settings and process the file in your browser, then download the compressed result and assess whether the output meets your needs.

MiniWebtool’s Video Cropper lets you draw a rectangle over a video to choose the retained picture area. Preview the crop and download the browser-processed result.

Keep a clip or divide a recording with MiniWebtool’s Video Splitter. Choose a segment, equal parts, fixed intervals, or custom cut points; browser-side fast mode cuts without re-encoding.

MiniWebtool’s Video to Image Extractor saves still frames from a video. Choose a timestamp or an extraction interval and select PNG, JPG, or WEBP for single or multiple image outputs.

MiniWebtool’s Webcam Test checks your camera in the browser with a live preview, measured frame rate and true resolution readout. Scan supported resolutions from VGA to 4K, run an automated Camera Health Check grading brightness and focus.
