Fix any video in seconds — no editor to launch, no subscription, no upload.
Every small clip task — rotate a sideways school recital, trim a two-hour interview down to ninety seconds, crop a wide shot to a Reels-ready 9:16, drop a 4K file under an email cap, swap MOV for MP4 — runs straight in your browser. The same ffmpeg desktop editors shell out to, just running in your tab.
Pick a tool, drop your clip, download — your video never leaves your browser
Pick your video tool
Ten tools, one job each. Rotate, flip, trim, crop, resize, merge, compress, watermark, swap format, extract the audio — every one runs in your browser using ffmpeg compiled to WebAssembly, so your clip never leaves your device.
Your clip was shot sideways and every player shows it wrong. Fix the orientation in one click — no re-encode, no software to install.
Rotate my videoThe selfie video is mirrored, the screen recording shows your camera flipped, the demo needs to point the other way. Flip horizontally or vertically and the new MP4 plays the right way in every player.
Flip my videoThe first ten seconds and the last twenty don't belong in the final cut. Trim them off in your browser, no editor needed.
Trim my videoInstagram wants a square, TikTok wants vertical, your edit was shot wide. Crop to the right aspect ratio in seconds.
Crop my videoYour clip is bigger than the upload accepts, or heavier than the connection wants. Resize the resolution without changing the framing.
Resize my videoTwo clips, ten clips, or thirty — drop them in, drag them into the right order, and download a single merged MP4. No watermark.
Combine my clipsYour video is over the email cap, the CMS limit, or the chat ceiling. Pick a preset, drop the resolution if you need to, and get it under the cap.
Compress my videoYour videos get screen-recorded and re-shared. Stamp your logo or handle on every frame so the brand travels with the file, even when the platform strips the metadata.
Add a watermarkThe CMS, LMS, or player won't open your MOV/AVI/MKV file. Convert any video to MP4 with H.264 + AAC inside — the format every device plays without complaining.
Convert to MP4You only need the soundtrack of a clip. Extract it as MP3 and skip the video file entirely.
Extract the MP3Why a thirty-second video fix wants a 4 GB editor install
Phones got better. The in-between tools didn't. Every small fix to a video still demands the same heavyweight editor your phone went around.
DaVinci, Premiere, iMovie — all built for projects
DaVinci Resolve is a 4 GB install. Premiere wants $22.99/month. iMovie ships with macOS but takes forty seconds to launch and another forty to import a one-minute clip, then asks where to save the "project" you didn't want.
Every desktop editor is built for the *project*, not the *single thirty-second fix* — they assume the file matters enough to live in a timeline, a library, a render queue. For "rotate this 90° and download" they're absurd.
Every platform sets a different cap and a different shape
Email caps at 25 MB. Discord at 25 MB free, 500 MB Nitro. The LMS won't accept anything over 100 MB. WhatsApp silently re-encodes anything over 16 MB on its own terms. TikTok wants 9:16, YouTube wants 16:9, Instagram feed wants square.
A phone clip that's perfectly fine on the device suddenly fails three different uploads in a row — and the desktop editor that would fix it is the one you're trying to avoid opening.
Video clips are unrepeatable — and you're uploading them to strangers
A school recital, a first birthday, a wedding speech, a client demo, a podcast interview — these are recordings you don't want to redo and that nobody else has. The embarrassment of sharing a sideways recital with the grandparents, or of an oversized clip that bounces at 25 MB the morning of the deadline, is sharper than for other formats.
And uploading a baby video to "Free Online Video Editor" so it can be re-encoded by a stranger's server feels exactly as wrong as it is.
Phones got better. The in-between tools didn't.
A phone shoots 4K because the phone shoots 4K — not because the recipient needs 4K. Rotating a clip is the same one-liner of metadata it was in 1999. Cropping a video to a different aspect ratio shouldn't require launching a 4 GB editor.
The fact that the obvious small fixes to a video file in 2026 either require a desktop install, a monthly subscription, or an upload to someone else's encoder is a failure of the toolchain.
“We know what it's like to have a great clip — the recital, the demo, the wedding speech — and to watch it bounce off an email cap, fail to play on the recipient's laptop, or arrive sideways on the family WhatsApp because the only tool that could fix it wants forty seconds to launch and a project folder.”
The same ffmpeg desktop editors use — running in your browser tab
Three steps. That's it.
Pick the tool that does the one thing you need, drop your clip in, download the fixed MP4.
Pick the video tool
Rotate, flip, trim, crop, resize, merge, compress, watermark, swap format, extract the audio — one tool per task, easy to bookmark.
Drop your clip in
Single file or a batch. The clip is decoded, re-encoded and saved entirely in your browser tab — no upload, no project folder.
Download the fixed MP4
The original is untouched. You get a clean new file ready to send wherever was asking — Discord, the LMS, the family group chat.
Without a free, local video toolkit
Small video problems don't seem like a big deal — until the upload bounces the morning of the deadline.
- The 4K phone clip from the school play won't go through email at 380 MB, and Premiere won't open in the ten minutes before the grandparent group chat asks "did anyone get it?"
- The recital is sideways on the family WhatsApp and the grandfather watches the whole solo with his head tilted
- The Reel goes up in 16:9 because the cropper you found wanted $14.99 first, and Instagram letterboxes it down to a postage stamp
- A colleague's .MOV interview won't play on the Windows recipient's laptop, and the back-and-forth eats the afternoon
- You install DaVinci Resolve for one rotation, lose forty seconds to launch and another forty to import, save a project file you'll never open again, and the disk is suddenly 4 GB lighter
From "I'll fix it later in iMovie" — to fixed in the same tab, in under two minutes
Before
- A 4K iPhone clip is 380 MB and bounces off the school's 100 MB upload cap minutes before the recital deadline
- The first-birthday clip is sideways on the family group chat and grandma watches it with her head tilted
- A `.mov` from a colleague's iPhone won't play on the recipient's Windows laptop, and the thread loops for an afternoon
After
- The clip compresses to 78 MB at 1080p in under two minutes, the upload accepts, and the recital makes the gallery
- The clip rotates 90° in seconds, the new MP4 plays the right way up in every player it touches, and the family group chat ends in heart emojis
- The `.mov` becomes a clean MP4 with H.264 + AAC inside, the recipient's default player opens it on the first try
