Resize Video for YouTube: Perfect 16:9 Uploads and 9:16 Shorts Features
EchoWave's YouTube tools are used by YouTubers, Shorts creators, and channel managers worldwide
Two formats, one tool
Stop letting YouTube choose your crop
YouTube gives you two shapes: 16:9 widescreen at 1920x1080 for the main watch page and 9:16 vertical at 1080x1920 for Shorts, and when you resize video for YouTube you decide how footage fits each one. Upload a phone-shot vertical clip as a regular video and YouTube pillarboxes it between black bars. Upload landscape footage as a Short and the crop lands wherever it lands. EchoWave's presets set the canvas to either format in one click, then position and scale controls let you choose exactly what stays in frame. Cutting a Short from a long video? Pair the resizer with the YouTube Shorts maker, or polish the full upload in the YouTube video editor.

What you get
Built for both YouTube formats
Presets, framing controls, and export settings tuned to how YouTube actually displays video.
-
16:9 and 9:16 Presets
Set the canvas to YouTube's 1920x1080 widescreen or the 1080x1920 Shorts frame in one click. The preset matches what the platform expects, so no math and no guessed dimensions.
-
Position and Scale Controls
Drag your clip anywhere inside the new canvas and scale it until the subject sits exactly where you want. You choose the crop deliberately instead of hoping YouTube's automatic framing gets it right.
-
Fill or Fit, Never Stretch
Fill crops the edges so footage covers the whole frame; fit keeps every pixel and adds a background instead. Neither option stretches anything. For pixel-precise edge trims, open crop video.
-
Full Editor Underneath
Resizing happens inside a multi-track timeline, so you can trim dead air, stamp a logo, or add music before exporting. Explore the full video editor when a clip needs more than a new shape.
-
Captions for Shorts
Auto-generate word-level captions in the same session after resizing to 9:16. Choose from 170+ styles, including karaoke fills, so your Short still works for the many viewers watching with sound off.
-
HD and 4K Export
Export MP4 in the resolution your plan allows: 720p with a small watermark on the free plan, 1080p on Basic, up to 4K on Pro. Resolution is chosen at export, independent of the ratio you picked.

Resize video for YouTube FAQ
How do I resize a video for YouTube?
Upload your clip to EchoWave's free online resizer, then pick a YouTube preset: 16:9 at 1920x1080 for a standard upload or 9:16 at 1080x1920 for a Short. Choose fill to crop the edges or fit to keep the whole frame over a background, drag and scale until the framing looks right, and export as MP4. The tool runs in your browser with no signup, so you can go from source clip to YouTube-ready file in a few minutes.
What size should a YouTube video be?
Standard YouTube videos are 16:9 widescreen, and 1920x1080, also called 1080p, is the size most channels upload. YouTube accepts higher resolutions in the same shape, up to 4K, which EchoWave exports on paid plans. If your source has different dimensions, resize it to 16:9 first so the player fills edge to edge with no black bars. Aspect ratio controls the shape while resolution controls the pixel count; the two are set independently, so pick the ratio first and the resolution at export.
What size is a YouTube Short?
Shorts are vertical: 9:16 at 1080x1920 pixels. Upload landscape footage to the Shorts feed and it gets cropped unpredictably, often cutting off faces or on-screen text. EchoWave's 9:16 preset sets the canvas to the exact Shorts size, and the position and scale controls let you decide which slice of a wider clip fills the tall frame, so the final crop is yours rather than the platform's.
How do I make a vertical video 16:9 for YouTube without stretching it?
Never stretch: a 9:16 clip forced to fill 16:9 looks warped immediately. You have two honest options in EchoWave. Fit keeps the entire vertical frame and fills the space beside it with a background, which works well for talking-head clips. Fill zooms the clip until it covers the 16:9 canvas, cropping the top and bottom, which suits footage with a centered subject and little vertical detail. Both keep pixels in their original proportions, and you can drag the clip to fine-tune what shows.
How do I turn a landscape video into a YouTube Short?
Pick the 9:16 preset, scale the clip until it fills the vertical canvas, and drag it so your subject stays centered; you are choosing one slice of the wide frame on purpose instead of letting an automatic crop decide. EchoWave's keyframes can even move the framing over time if your subject walks across the shot. If you are cutting several Shorts from one long video, the YouTube Shorts maker pairs this resizing with trimming and captions.
Does resizing a video reduce quality?
Changing aspect ratio does not degrade footage by itself: EchoWave repositions and scales your clip on a new canvas rather than re-stretching pixels. Quality is set by your export resolution. Free editor exports are 720p with a small watermark, Basic unlocks 1080p, and Pro exports up to 4K, so a 1920x1080 upload can leave the editor at full quality. Scaling a clip up dramatically to fill a frame can soften it, which is another reason to shoot close or use fit instead.
Do I need a new thumbnail after resizing my video?
Usually, yes. A thumbnail framed for widescreen rarely reads well once the video becomes a vertical Short, and a pillarboxed vertical clip makes a poor auto-generated thumbnail for a standard upload. After resizing, scrub to the strongest frame and capture it with the video thumbnail grabber, which saves a PNG or JPG at the video's own resolution. For standard uploads, set that image as the custom thumbnail in YouTube Studio.
Is the YouTube video resizer free?
Yes. The standalone resize tool is free with no signup: upload a clip and download the resized result. If you finish the job inside the full editor, free exports include a small watermark and cap at 720p, while paid plans remove the watermark and export up to 4K. Posting beyond YouTube too? The same presets cover 1:1, 4:5 and every other shape in the general resize video tool.
