Free Video Upscaler for 1080p and 4K
iLoveVideos is a free video upscaler for increasing compatible clips to 720p, 1080p or 4K without uploading them to a server. Processing stays in your browser, preserves the original aspect ratio and keeps supported audio tracks in sync.
Use it to upscale video online from 480p to 1080p, 720p to 1080p or 1080p to 4K. This video quality enhancer uses high-quality local scaling and WebGPU detail processing where available. Upscaling cannot recreate missing detail, and 4K speed depends on the video length, codec and device.

FAQ
Frequently Asked Questions
Is my video uploaded to a server?
No. Your video is decoded, upscaled and encoded locally in your browser. The file is never sent to our server.
Can I upscale a video to 1080p?
Yes. Videos below 1080p can be upscaled to 1080p, while 1080p sources can be upscaled to 4K. Lower output options are never offered.
Can I upscale a video to 4K?
Yes. Videos below 2160p can be upscaled to 4K when your browser and device support the required encoding. Longer 4K jobs need more time and storage.
Can I convert a 480p video to 1080p?
Yes. Select a 480p video, choose 1080p and the tool will preserve its original aspect ratio while upscaling.
Can I upscale 720p video to 1080p?
Yes. A 720p source can be upscaled to 1080p or 4K without changing its aspect ratio.
Does the upscaled video contain a watermark?
No. Downloaded videos do not contain an iLoveVideos watermark.
Do I need to create an account?
No account or signup is required. Choose a video and start immediately.
Is ilovevideos.online free?
Yes. The current browser video upscaler is free to use.
What video formats are supported?
Common files such as MP4, WebM, MOV, M4V and MKV work when your browser supports the video's codec. The latest Chrome or Edge is recommended.
Does video upscaling reduce quality?
Upscaling increases resolution but cannot recreate detail missing from the source. High-quality scaling and encoding are used, though re-encoding can introduce small changes.
