Resize a video to 1080x1350, the 4:5 portrait frame for Instagram feed posts.

Why 4:5 and not 9:16

4:5 is the tallest shape a feed post is allowed to be. It takes more vertical space on a phone than a square, which pushes competing posts further down the screen, and it does so without the platform cropping anything.

9:16 belongs to Stories and Reels, which are full-screen surfaces. A 1080x1920 clip sent to the feed gets cut down on arrival, and the framing you chose is not the framing that survives.

Coming from other shapes

Source	What is cut	Kept
1920x1080	cuts 528 px from each side, keeps 864 of 1920 columns	picture 1080x608, 371 px of background top and bottom
1080x1080	scales up and cuts 20% of the width	picture 1080x1080, 135 px top and bottom
1080x1920	285 px from the top and bottom	the full width, which already matches

Safe areas

The caption, the username, and the action row sit below a feed video rather than over it, so the whole frame is usable. That is the practical advantage over a Story, where the bottom fifth is covered.

Text burned into the bottom of a 4:5 clip still risks being clipped in the grid preview, which crops the post back to a square. Keep anything critical inside the middle 1080x1080.

Frequently Asked Questions

Why 1080x1350 and not 1080x1920?

4:5 is the tallest shape an Instagram feed post accepts without cropping it. 9:16 is for Stories and Reels, which are full-screen surfaces. A 1080x1920 clip posted to the feed gets cut down.

How much of a 1920x1080 video is lost?

55%. The tallest 4:5 slice of a 16:9 frame is 864 pixels wide, so crop to fill cuts 528 pixels from each side.

Is 4:5 better than square for the feed?

It occupies more vertical space on a phone screen, so it pushes competing posts further down. That is the only structural difference.

What happens to a 1080x1080 square clip?

It is scaled up until it covers the taller frame and the sides are cut, losing 20% of the width. To keep all of it, pad it in the video cropper instead, which leaves 135 pixels of background top and bottom.

Video Cropper

Change a video's frame: crop to 16:9, 9:16, 1:1, 4:5 and ten more ratios by dragging a box over the preview, or fit the whole picture into the new ratio with black, white, or blurred bars instead of cutting the sides off.

Video Resizer

Resize a video by width, by percentage, to fit inside a box, or to cover an exact frame such as 1080x1920. The soundtrack is carried through or dropped.

Engraving Video Effect

Turn every frame of a video into an antique engraving: hatch lines that follow the form, crosshatching in the shadows, and etched edges that move slightly on every frame. Set ink and paper colors, exposure, and line density. Exports MP4 or WebM with the original soundtrack.

Linocut Video Effect

Carve every frame of a video into a linocut print: solid ink shapes, gouged midtone lines, and ragged cut edges that shift on every frame. Set simplify, ink threshold, gouge spacing, and edge carve. Exports MP4 or WebM with the original soundtrack.

Night Vision Video Filter

Turn a video into night-vision footage: brightness mapped to green, white, amber, or blue phosphor, with gain, highlight bloom, and grain that moves on every frame. Exports MP4 or WebM with the soundtrack.

Sketch Video Effect

Turn a video into a moving pencil drawing: graphite shading, traced contours, and paper texture that is redrawn on every frame. Set paper color and each layer's strength. Exports MP4 or WebM with the original soundtrack.

Video Volume Booster

Make a video louder by up to 24 dB with a limiter that holds peaks below a ceiling, so the boost does not clip or distort. The picture is copied untouched. Exports MP4, WebM, MOV, or MKV.

Add Subtitles to Video

Burn SRT or VTT subtitles into a video with your choice of size, position, and outline, or add them as a subtitle track viewers can switch off. Shift the timing when the file is out of sync.

Audio Visualizer

Turn an audio file into a video with animated spectrum bars, a radial meter, or an oscilloscope waveform. Pick colors, a caption, and a 16:9, 9:16, 1:1, or 4:5 frame, and export an MP4 with the audio included.

Colored Pencil Video Effect

Turn a video into a moving colored pencil drawing: dark strokes along edges, light paper where the frame is flat, and angled pencil texture. Set detail, color retention, paper texture, and stroke angle. Exports MP4 or WebM with the original soundtrack.

CRT Video Effect

Make a video look like it is playing on a CRT television: barrel curvature, scanlines, a phosphor mask, color bleed, and glow, with fresh static on every frame. The soundtrack is copied into the MP4 or WebM export.

Dispersion Video Effect

Break the edges in every frame of a video into particles that drift left, right, up, or down, with a new particle layout on every frame. Set particle amount, travel distance, edge threshold, and direction. Exports MP4 or WebM with the original soundtrack.
