A free online video editor that runs in your browser

What you can do, task by task

Cut and assemble: Trim Video keeps only the part you need, with start and end sliders and a preview. Merge Videos joins several clips in the order you choose. Remove Silence cuts the quiet pauses out of talking-head videos, tutorials and podcasts. Change Video Speed plays a clip from 0.25× to 4×, and Loop Video repeats it 2 to 10 times.

Frame it for each platform: Crop Video reframes to 9:16, 1:1, 4:5, 16:9 or 4:3 with a position slider. Resize Video fits or fills presets such as 1080×1920 for TikTok, Reels and Shorts, or 1920×1080 for YouTube. Rotate Video fixes a sideways phone recording.

Sound, text and privacy: Auto Subtitles transcribes speech with an AI model (Whisper) that runs on your device, lets you correct the transcript, then exports SRT or WebVTT or burns the captions into the picture. Remove Audio strips the sound track. Blur Video pixelates a fixed area, such as a license plate or a screen, over a time range.

Export: Compress Video shrinks a file to a target size in MB, for Discord, email or a form. Video to GIF turns a short moment into a looping GIF. Video Converter changes the format to MP4, MOV or WebM.

How chaining works

Each tool does one job well. When it finishes, the result screen shows “Continue with this file” and a few tools that usually come next. One click opens that tool with your result already loaded: no download, no new file picker, no upload.

A typical short-form workflow: Remove Silence to tighten a talk, then Trim Video to keep the best minute, then Crop Video to 9:16, then Compress Video to fit an upload limit. The suggested tools depend on the step you are on; if the one you want is not listed, download the result and open it in that tool.

Chaining also protects quality. Some steps copy the streams without re-encoding: fast trimming, merging clips with identical settings, rotating an MP4 or MOV, removing audio and looping. The page says “Lossless / no re-encoding” when that happens. Put the steps that re-encode, such as cropping, burned-in subtitles and compression, at the end, ideally with compression last.

Not a timeline editor, and who should use one

Vidmini has no multi-track timeline, no transitions, no text or sticker overlays, no templates, no music library and no saved projects. If you are building a video from many shots with titles, B-roll, music and effects, a full timeline editor (desktop or online) is the right tool, and you will go back and forth on the same project for days.

Vidmini is the better fit for quick edits on a single video: cut a recording, reframe it for a phone, add subtitles, get it under a size limit. It suits people who don’t want to create an account, who handle private footage, or who are on a slow connection where uploading a large file to an online editor would take longer than the edit itself.

Private, free, and it works offline

Online video editors usually upload your footage to a server. Vidmini processes it inside your browser with the WebCodecs API, your device’s hardware encoders when available, and WebAssembly. Nothing is uploaded, there are no tracking cookies, and the page’s Content Security Policy only lets it talk to vidmini.com for its own code.

There is no watermark, no account and no paid tier to remove limits. Once a tool page has loaded, the processing works without a connection. Two components are downloaded from vidmini.com the first time you need them: the subtitle model (about 68 or 102 MB) and a 32 MB converter for older formats. Your video is still never sent anywhere.

Limits worth knowing

There is no file size limit set by us: results are streamed to your browser’s private storage, so desktop browsers handle files of several gigabytes. On phones, free memory and storage set the practical limit. Speed depends on your device, not on a server queue.

MP4, MOV (including iPhone videos), M4V, WebM and MKV open natively. AVI, WMV, FLV, MPEG, 3GP and similar formats go through a slower on-device converter that accepts files up to 1 GB. Auto Subtitles transcribes but does not translate, and handles up to 3 hours of audio. Blur Video does not follow moving objects. HDR videos from recent iPhones may look slightly faded after re-encoding.

Which browsers work

The latest versions of Chrome, Edge, Safari and Firefox, on desktop and on mobile. Chrome and Edge decode the widest range of codecs, so they are the safest choice for unusual files; Safari handles iPhone HEVC videos well. The whole site is available in English, French, Spanish, Portuguese and German.
