About Changing Video Resolution

Video resolution refers to the number of distinct pixels displayed in each frame (width × height). Changing or lowering video resolution—such as downscaling a 1080p Full HD clip to 720p HD—is commonly used to meet platform upload limits, reduce bandwidth consumption, or standardize media files for websites, presentations, and online courses.

All video processing runs 100% locally in your browser using hardware-accelerated Canvas and MediaRecorder APIs. Your video files are never uploaded to any remote server or stored in the cloud, ensuring full data privacy.

How to Change Video Resolution Online

Upload Your Video: Select or drag and drop your MP4 or WebM video file into the dropzone.
Select Target Resolution: Choose your desired output dimensions (e.g., 1080p, 720p, 480p, or 360p) from the dropdown menu.
Process & Download: Click "Change Video Resolution" to encode the new video locally and save your file.

Common Video Resolutions

This tool supports standard 16:9 widescreen resolutions for web, mobile, and desktop playback:

Resolution	Common Name	Aspect Ratio	Typical Use
1920 × 1080	1080p (Full HD)	16:9	High-definition web, desktop monitors, and TV displays
1280 × 720	720p (HD)	16:9	Balanced quality and size for web streaming and social video
854 × 480	480p (SD)	16:9	Standard definition for email sharing, LMS, and presentations
640 × 360	360p (Low Res)	16:9	Lightweight mobile delivery and low-bandwidth connections

Note on vertical video: Smartphone recordings and vertical formats (such as 1080 × 1920 for Shorts, Reels, and TikTok) use a 9:16 portrait aspect ratio.

Lowering Video Resolution vs. Compressing Video

Changing resolution alters the physical pixel grid of the video frames. In contrast, video compression primarily adjusts the encoding bitrate and compression factor without necessarily reducing pixel dimensions.

If you want to keep your original resolution (such as 1080p) but need a smaller file size, use our dedicated Video Compressor tool instead.

Video Resolution FAQs

How do I change the resolution of a video?

Upload your video, choose a target resolution from the dropdown menu (such as 1080p, 720p, or 480p), and click Change Video Resolution to export your new file.

Can I lower a 1080p video to 720p?

Yes. Select 1280 x 720 from the output resolution dropdown. The tool will downscale your 1080p frames and re-encode the video with matching 720p dimensions.

Does lowering video resolution reduce file size?

Usually yes. Fewer pixels per frame typically reduces the data required to encode the stream, though final file size also depends on video duration, codec, and bitrate.

Can I change video resolution without uploading it to a server?

Yes. All processing runs 100% locally in your web browser using HTML5 Canvas and MediaRecorder. Your video never leaves your computer.

What video resolution should I choose?

Choose 1080p for full-screen desktop viewing, 720p for the best balance of quality and file size for web platforms, or 480p/360p when smaller files are required.
