⚠️ Performance Warning
- If you don't have a graphics card (GPU), rendering will be slow. A GPU finishes short clips in seconds, a CPU can take several minutes.
- Please upload large files (close to 400 MB) one by one or in very small batches.
- Do not upscale 4K resolution for all files at once. Please try batches of 2 to 5 files for 4K.
- Processing speed depends heavily on your GPU, CPU, and system memory.
- Mobile devices will be significantly slower than laptops and desktop PCs.

How do I upscale a video for YouTube for free?
Drop your video into the tool above, keep the 1080p target, click Start Upscale and download the 1920x1080 MP4. It runs on your own device, so nothing is uploaded and no watermark is added. 1080p is the standard for YouTube, but if you want to force the platform to use its best compression (VP9), set the target to 4K. It sharpens what is already in your video and cannot recover detail that was never recorded.

What each resolution becomes for YouTube
YouTube assigns different codecs based on your video's resolution. By upscaling, you ensure your hard work gets the bitrate it deserves.
| Your video | Scale | What to expect |
|---|---|---|
| 480p (854x480) | 2.25x | Good for old YouTube videos. Use Resolution mode. |
| 720p (1280x720) | 1.5x | The most common upgrade. YouTube gives 1080p a much better bitrate. |
| 1080p (1920x1080) | 2x | Upscale to 4K. YouTube uses the VP9 codec for 4K, which looks much sharper. |
How to upscale for YouTube in 3 steps
- 1
Drop your YouTube video
Select the original video file you want to upload to YouTube. It is processed locally and never uploaded.
- 2
Choose 1080p or 4K
1080p is the YouTube standard. If you want the best bitrate (VP9), upscale to 4K.
- 3
Upscale and upload
Download the MP4 and upload it to YouTube Studio. The algorithm favors higher resolutions.
Which quality setting should I pick?
The presets apply to the CPU engines. When your GPU is used, the AI pass runs at its own fixed quality, so you can leave the setting alone.
Fast
Quickest. Best on CPU-only devices and for long vlogs.
Balanced
Bicubic scaling. A good middle ground between time and sharpness.
Best
Lanczos scaling, the sharpest. Use it for short, important videos.
What YouTube upscaling can and cannot do
What works well
- Turn 480p or 720p footage into a true 1920x1080 file
- Turn 1080p footage into 4K to trigger YouTube's VP9 codec
- Sharpen soft edges and lines compared with plain resizing
- Keep your audio on MP4 output and upscale up to 10 videos in one batch
What to keep in mind
- Add detail that was never recorded in your gameplay or vlog
- Fix bad lighting or shaky camera work
- Process files over 300 MB or 3 minutes
- Guarantee higher views or monetization

Upscale for YouTube: questions people ask
Why should I upscale my video for YouTube?
YouTube gives higher bitrate (better quality) to 1080p and 4K videos. Upscaling your 720p video to 1080p ensures YouTube processes it with a better codec, making your content look sharper.
Does this help with YouTube monetization?
Monetization requires original content, but better resolution and sharpness can improve viewer retention and watch time, which indirectly helps your channel.
Can I upscale my YouTube Shorts?
Yes. The tool automatically detects vertical video. A 720x1280 Short can be upscaled directly to 1080x1920.
Is it safe to upload my video here?
You are not uploading anything to our servers. The video is processed entirely in your browser using your device's GPU or CPU.
Does upscaling to 4K bypass YouTube compression?
YouTube always compresses video, but 4K uploads get the VP9 codec, which preserves much more detail than the AVC codec used for 1080p. It is a common trick among creators.

Your videos never leave your device
There is no upload step and no server-side video handling. The video is decoded, upscaled and re-encoded in your browser using WebCodecs and, when available, WebGPU. Open the browser Network tab while upscaling and confirm that no request carries your file. Read how we keep it private.
