Free Online Video Tools
Browser-based video tools powered by FFmpeg.wasm for trimming, merging, compressing, format conversion, audio extraction and GIF creation.
All Video Tools
Trim VideoCut a selected time range from a video, set start/end times manually or from the current playhead, choose MP4/WebM output and advanced codec/CRF settings.Merge VideosJoin two or more video clips in selection order, choose MP4/WebM output, standardize resolution, frame rate and CRF quality, then download one video.Video CompressorReduce video file size using quick presets or custom resolution, CRF, FPS, audio bitrate and x264 encoding-speed controls; output is MP4.Video ConverterConvert video to MP4, WebM or MOV and optionally change resolution, frame rate, CRF quality and audio bitrate in the browser with FFmpeg.wasm.Video to MP3 / Audio ExtractorExtract the audio track from a video and save MP3, WAV or M4A with selectable bitrate, sample rate, channel count, start time and duration.Video to GIF ConverterConvert a selected video segment to an animated GIF with configurable start time, duration, width, FPS and loop count using palette generation for better color mapping.
Guides and explanations
How to Reduce Video File SizeUnderstand the main levers behind video size: resolution, CRF, frame rate, audio bitrate, encoder preset and duration.CRF Video Compression ExplainedA technical but practical explanation of Constant Rate Factor, why lower values usually mean higher quality, and why CRF does not guarantee an exact file size.MP4 vs WebM for Video ConversionCompare MP4/H.264/AAC and WebM/VP9/Opus in the context of this browser-based converter.How to Convert Video to MP3 and What Bitrate MeansUnderstand audio extraction, MP3 bitrate, sample rate, mono/stereo and why WAV files are much larger.How to Make a Smaller Video-to-GIF ConversionLearn why duration, width and FPS strongly affect GIF size and why GIF can be larger than MP4.
How this collection is organized
Each tool has its own crawlable URL, unique title, description, documentation, structured data and contextual links. This helps users and search engines distinguish tasks that may sound related but operate differently—for example cropping versus resizing, PDF merging versus page extraction, or video conversion versus compression.
