How do I crop a video online?

Drop your video, select an aspect ratio preset (16:9, 9:16, 4:3, 1:1) or drag to draw a custom crop area, preview the result, then click Crop.

What aspect ratio presets are available?

16:9 (widescreen/YouTube), 9:16 (vertical/Instagram Stories), 4:3 (classic), and 1:1 (square). Free-form cropping is also available for custom dimensions.

Will cropping reduce video quality?

Encoding parameters remain unchanged - only the frame region changes. Quality is essentially lossless, though cropping to a very small region and then upscaling may show pixelation.

Can I crop video without re-encoding?

The tool re-encodes to produce a clean output with the cropped dimensions. This ensures maximum compatibility across all players and devices.

Is video cropping safe?

Completely safe. All processing happens in your browser. Your video files are never uploaded to any server.

What video formats can I crop?

Supports MP4, WebM, and MOV input formats. Output preserves the original format.

Preparing videos for Instagram Reels, TikTok, Shorts, and square feeds

Format Notes

Aspect ratio presets help you match the destination platform before export.
Cropping changes the visible frame, so it is best used when composition matters more than preserving the full image.
Vertical 9:16 and square 1:1 crops are especially useful for mobile-first publishing.

Practical Tips

Pick the destination aspect ratio before you export to avoid re-editing later.
Keep the main subject centered when converting widescreen footage to vertical output.
Crop first, then trim or compress if you also need a shorter or smaller file.
