Video
Videos of up to 500 MB that this browser can play: usually MP4, WebM and MOV. Frame steps move one picture of the video.
Cut and trim
Tool
Click a clip on the timeline to choose it; the playhead stays where it is (click the ruler above the clips or the Sound row to move it). With Cut, a click on the picture or on a clip splits there; with Trim, drag the start and end of the edited video.
Selection
Turn and flip
Look
Look
A shape keeps the middle of the picture and cuts the sides or the top and bottom, in the preview and the saved video.
Colour grading
Warmth adds red and takes away blue, or the other way. Shadows lifts or deepens the darkest parts, Midtones the middle greys and Highlights the brightest parts.
Speed
Speed ramp
The speed changes smoothly from one speed to the other, starting at the playhead, then goes back to the speed above.
Text and subtitles
Drag a text on the picture to move it, or type where its middle goes in percent.
Subtitles
Fades and transitions
The saved video starts from black and ends in black over these seconds.
A transition plays as a clip begins, from the last picture of the clip before it (or from black at the start). Split the video to make clips.
Sound
Sound fades
No sound fades.
Music and other sound
Imported sound plays from the start of the saved video at its own speed. Up to five files of up to 200 MB.
Video layers
A layer is another video drawn over yours from the start of the saved video, without its sound. Up to five layers. Layers and imported sound are not kept in project files or in this browser: add them again when you come back.
Green screen
Green screen works on your video layers: the chosen colour becomes see-through, so the main video shows behind them.
Markers
Shift+M goes to the previous marker and Shift+N to the next.
Keys while you use the tool: Space plays, S splits, I and Shift E select, M adds a marker and ? opens the help. Nothing you open leaves this browser.
How to Use WebEdit Pro
Cut what you do not need
Split at the playhead, select a part and delete it, or drag the ends of a clip to trim it. Turn or flip the picture and pick a shape such as 9:16 for phones.
Fix the colour
Change brightness, contrast and saturation, try the eight looks, or grade warmth, tint, shadows and highlights. The Color Harmonizer can match your video to another one.
Add text and subtitles
Put a title or caption on the video and drag it into place, and add subtitles from the playhead. Save the subtitles as an SRT file too if a video site asks for one.
Add music and effects
Import music, set the volumes, fade the sound in and out, add fades and transitions, change the speed, or lay another video over yours with green screen.
Save the video
Choose the size and MP4 or WebM and press Save video. It records the edited video as it plays, so keep the tab open until it is done.
Why Use WebEdit Pro?
🎬 A whole editor on one page
Cutting, colour, text, subtitles, music, transitions, layers and saving are all in one place, with undo for every step, so a short video can be finished without installing anything.
👀 The preview is the saved video
The preview is drawn the same way as the saved video, frame by frame: the cuts, turns, shapes, colours, texts, layers, fades and transitions you see are the ones you get.
🎚️ Sound mixed in
The video's own sound and up to five music or voice files play together, each with its own volume, and the whole mix can fade in and out. What you hear is what is recorded.
📱 A shape for every screen
Turn a wide video into an upright 9:16 one for phones, a square for posts or a 21:9 cinema strip, and save it at 720p, 1080p, 4K or its own size.
💡 Your edit is kept
The cuts, colours and texts stay in this browser, so you can close the page and carry on later with the same video, or save the edit as a small project file.
🔒 Nothing uploaded
There is no account and no upload. Your video is played, edited and recorded by this browser on this device, so even long or private videos stay with you.
Video Editing Explained
⏺️ How saving works
The browser plays your edited video from start to end and records the frames and the sound as they are drawn, then gives you the file. That is why saving takes about as long as the video, and why the tab must stay open and in front while it records.
🎞️ Clips, joins and transitions
A clip is a part of your video that you keep. Where one clip ends and the next one begins there is a join; without a transition the picture changes at once, while a fade, dissolve, wipe or slide makes the change softer.
📐 Shape and size
A shape such as 16:9 or 9:16 is the ratio of width to height. The size is counted on the shorter side: a 1080p widescreen video is 1920 x 1080 pixels and a 1080p upright one is 1080 x 1920. Larger sizes look sharper and make larger files.
Frequently Asked Questions
Is WebEdit Pro free, and is my video uploaded?
It is free, with no registration. Like every page on ZeroDataUpload, it is supported by advertising. The videos, pictures and sound files you open are played and edited in this browser and are never sent to a server. Your edit (the cuts, colours, texts and so on, not the video itself) is kept in this browser, so it comes back when you open the same video again; New project removes it.
How long does saving a video take, and why?
Saving plays your edited video from start to end and records the preview as it plays, so it takes about as long as the saved video: a 5-minute video takes about 5 minutes. The Save window shows the length before you start and the time left while it records. Keep the tab open and in front: a hidden tab pauses the recording until you come back.
Will I get an MP4 or a WebM file?
You choose MP4 or WebM. MP4 is made where your browser can record it, which recent Chrome, Edge and Safari can; where it cannot, the file is saved as WebM and the Save window says so before you start. The file name always ends in the format the file really has.
How do I cut out a part of my video?
Move the playhead to where the part begins and press Start selection (or I), play or move to where it ends and press End selection (or Shift+E), then press Delete selection. You can also press Split (or S) at both ends, click the clip between them on the timeline and press Delete. The saved video jumps over removed parts, and Undo brings them back.
How do I add music to a video?
Open the Sound group, press Import sound and pick a music or voice file. It plays from the start of the saved video at its own speed, with its own volume and mute, beside the video's own sound, and both are recorded into the saved file. The sound fades work on the whole mix; Normalize works on the video's own sound.
How does the green screen work?
Add a video filmed in front of a green or blue background as a video layer, place and size it, then in Green screen pick the background colour and press Turn green screen on. That colour becomes see-through, so your main video shows behind the person or object. Similarity sets how close a colour must be to disappear and Smoothness softens the edge.
How is WebEdit Pro different from the site's other video tools?
GIF Forge turns a part of a video, a screen recording or pictures into a short GIF or clip. The media converter changes a file from one format to another. WebEdit Pro is a video editor: you cut and arrange the parts you keep, change the colour, add text, subtitles, music, fades, transitions and video layers, and save the result as a new video.
