Removing black bars instead of adding them
Black bars are letterboxing (bars top and bottom) or pillarboxing (bars at the sides): padding that gets added when a frame is scaled into a shape it does not fit. Scaling does not remove bars, it creates them.Cropping is the opposite operation. It cuts the frame down instead of padding it out. If your source already has bars baked in, drag the crop box to the edges of the real picture and export; everything outside the box is discarded.Going the other way, a 16:9 video that would sit between bars on a vertical feed fills the screen if you crop it to 9:16 first. The video resizer scales the whole frame instead, which is the right tool for hitting an exact pixel size, not for killing bars.Big files and long recordings
Every crop runs locally in the browser, so there is no upload, no queue, and no round trip to a server. File size costs you your own CPU and memory, not a transfer.The uploader accepts a file up to 500 MB, and nothing caps the clip length: a long screen recording or a full episode crops the same way a 10 second clip does, it simply takes longer to encode.If a file is larger than 500 MB, run it through the video compressor first and crop the smaller copy.Formats the cropper reads and writes
It reads MP4, MOV, WebM, and MKV, plus M4V and 3GP, which are MP4-family files wearing a different extension. AVI is not on the list: send it through the AVI to MP4 converter and crop the MP4.For the output you pick MP4, WebM, MOV, or MKV per export. Cropping a MOV does not force you into MP4, and cropping an MP4 does not force you out of it. MP4 is the safe default because upload flows expect it; WebM is the web-native option, and MKV is the flexible container desktop players handle well.Aspect ratios, and which one to pick
Each preset snaps the largest box of that shape that fits inside your source, centered, and you drag it from there. Original leaves the full frame so you can draw any box by hand.9:16 is the full-screen vertical frame for TikTok, Instagram Reels, and YouTube Shorts (1080x1920 at 1080p). 4:5 and 1:1 are feed shapes for Instagram and other square-ish placements. 16:9 is the standard landscape frame for YouTube and desktop players. What you are choosing here is aspect ratio, the shape of the frame, not its pixel size.Platform pages open on the right preset for you: crop for TikTok, crop for Instagram Reels, crop for YouTube Shorts, and landscape to portrait.Crop, trim, resize, or convert
Cropping changes the shape of the frame by discarding pixels at the edges. The clip stays the same length and the same resolution inside the box.Cutting the length is trimming: video trimmer. Scaling the whole frame to an exact pixel size is resizing: video resizer. Swapping the container alone is converting: video converter. Fixing a sideways phone clip is rotating: video rotator.If your subject moves around the frame and one fixed box cannot follow, the Shorts converter tracks faces frame-by-frame and re-centers the vertical crop as they move.Questions & answers
Live preview shows the cropped frame in real time as you drag the crop box, and the crop area readout gives the exact pixel dimensions you are keeping. What you see is what you get.
Crop them off. Bars are letterboxing: padding added when a frame is scaled into a shape it does not fit. Drag the crop box to the edges of the real picture and export; the bars sit outside the box, so they never reach the output file.
The uploader accepts files up to 500 MB, and nothing is uploaded: the browser reads the file straight off your disk, so there is no transfer and no queue. Over 500 MB, shrink it with the video compressor first, then crop the smaller copy.
No. Nothing caps the clip length, so a long screen recording crops exactly like a 10 second clip does. Length only shows up as encode time on your own machine, because the work happens locally.
MP4, MOV, WebM, and MKV, plus M4V and 3GP (both MP4-family files with a different extension). AVI is not on that list: convert it with the AVI to MP4 converter first, then crop.
Yes. Output format sits next to the crop controls, so one export gives you both the new frame and the new container. For a format change with no crop, use the video converter.
Pick the 9:16 preset and drag the frame over your subject. There are also dedicated pages for TikTok, Instagram Reels, and YouTube Shorts crops.
Yes. The presets (Original, 16:9, 9:16, 1:1, 4:5) are shortcuts; dragging the box on the preview sets any crop you want, down to the pixel.
No. The pixels inside the crop area keep their original quality; only the edges outside the box are discarded.
Yes. The export is a clean file with no watermark and no paywall; downloading takes a free account. Everything runs locally in your browser.
No. Cropping runs in your browser, your video never leaves your device, and we keep nothing.
Yes. That's a 9:16 crop of a 16:9 frame; the landscape to portrait converter walks through exactly that.
That is trimming, not cropping. The video trimmer cuts a section out of the timeline; cropping leaves the clip the same length and only changes the frame.
Cropping cuts pixels off the frame edges. The video resizer scales the whole frame to a new size without discarding pixels, which is how bars appear in the first place.
