Top Video Resolution Enhancer Online Tools

In a bid to find the best free video resolution enhancer, we have tested the 5 popular web-based options. Here are our findings and experience of using each tool. See if it meets your requirements and expectations. 

1. Vmake

Trustpilot Ratings3.6/5

Supported OS - free video resolution enhancer online tool

Vmake is a video resolution enhancer online freetool known to boost life into low-quality videos and images. It was developed to generate stunning clarity and high resolution with AI. Supporting multiple formats, it offers batch conversion for quick results. Newbies and novices can easily access its user-friendly interface without prior technical knowledge. 

Speed and Effectiveness Test 

We uploaded a 144p (H.264) MP4 music video to the free platform. It offered UHD and 4K enhancement options. And we opted for 4K. The processing took barely 10 to 12 seconds, and our enhanced video was right in front of us. Talking about the effectiveness, the video quality did enhance, but it was neither close to 4K nor UHD. There were barely any visible changes. 

video enhancement by vmake ai

Our Experience on This Video Resolution Enhancer

Our experience at Vmake was underwhelming. We could easily drop and paste files into the interface. While the speed was quick enough, it didn't make any sense to us as the video offered only a 5-second watermark-free preview and download. To download the full video, we were asked to subscribe to Vmake Pro. However, the results did not seem satisfactory or even close to being enhanced.  

Pros

  • Does not require sign-up or account creation.

  • Supports multiple formats: .mp4, .m4v, .mov, etc. 

  • Watermark-free video clips output.

  • Supports batch enhancement of multiple videos at once.

  • Simple, navigable, and clean interface with no ads or pop-ups.

Cons

  • Requires a Pro subscription for full video download.

  • Only a 5-second preview and download in the free version.

  • Contrary to its claims, it does not enhance the video.

  • Terrible processing speed; it took 10-12 seconds only to process a 5-second video clip.

2. CutOut.Pro 

Trustpilot Ratings1.6/5

Supported OS - video resolution enhancer online tool

CutOut.Pro is another free video resolution enhancer for casual users. It improves the overall video quality, converting the low-quality videos to high resolutions like 2K, 30 fps, and so on. Just ensure not to upload a file size beyond 2GB, as the platform may not support it. Upload either .mp4, .mov, .webm, or .gif for an enhanced video experience. 

Speed and Effectiveness Test

Similar to Vmake, we uploaded the same 144p H.264 MP4 music video to the platform. The processing time took over 30 seconds to upload and process a 1-second output clip. While the enhancement effectiveness was not very clear in that clip, it did mention that the preview (enhanced) video is of 360P quality. 

cutout.pro performance

Our Experience on This Video Resolution Enhancer

Our experience at CutOut.Pro was not very pleasant. We tested its free version by uploading a low-quality video clip, but it did not enhance it much (just 360P). While there was a preview option available, it did not have a download button to save the output (1-second) clip. In addition, it required us to log in with our Google or Facebook accounts. We proceeded with our Google credentials in the hopes of exploring the platform further and downloading the video clip. Sadly, it refused any downloads due to a lack of credits. Overall, it was not worth a try. 

Pros

  • User-friendly interface and easy navigation.

  • Does not require prior technical knowledge to operate the platform.

  • Supports image and video formats such as MOV, MP4, WebM, and GIF.

  • Cuts the reliance on desktop tools or mobile apps.

Cons

  • Requires buying credits or subscribing to process the video clips on the platform.

  • The max. file size (video) that can be uploaded is 2GB.

  • The max. video resolution is 4K.

  • The free version lacks a download option.

  • Offers only a 1-second preview clip (at 360p in the free version).

3. Airbrush 

Trustpilot Ratings1.5/5

Supported OS - online video resolution enhancer free

Airbrush is also a popular video resolution enhancer freeoption to improve video quality. You can upload a low-quality video clip, and it will enhance the footage to 4K, 30fps, and so on. Leveraging AI capabilities, Airbrush works seamlessly on files less than 200 MB in size or up to 10 minutes. It works effortlessly to clear blur and transform the video clips with its cutting-edge technology. 

Speed and Effectiveness Test

We uploaded the same low-quality music video clip in Airbrush. It took approximately 15 to 20 seconds to process the video footage and generate a 5-second clip. Compared to the previous two tools, Airbrush performed slightly better. The results generated in the output video seemed visibly enhanced compared to the original clip. 

airbrush video resolution enhancer online

Our Experience on This Video Resolution Enhancer

Our experience at Airbrush was fine and not as bad as compared to the earlier AI video resolution enhancersthat we tested. We had uploaded a 5.5 MB video of 4 minutes 10 seconds, so it processed efficiently without trouble. After processing, it gave us options to compare the original and preview videos. And the results showed visible enhancement. Even the user interface was simple and easy to work with. However, based on a 5-second preview clip, we can’t confirm whether it’s worth upgrading to the pro version.

4. Flixier 

Trustpilot Ratings4.0/5

Supported OS - video resolution enhancer online

Flixier is a renowned AI-based online video resolution enhancer proven to enhance and upscale videos to 4 K. Harnessing powerful AI, it makes any video look great effortlessly. Plus, it also gives manual controls to adjust the video output for a more personalized look and feel. With Flixier, you can not only sharpen and detail enhancement, but also correct color, filters, noise, and other necessary parameters. 

Speed and Effectiveness Test

We run the same music video here as well. Overall, it took approximately 8 to 10 seconds to upload and process the video. Going by the effectiveness, with Flixier, we could adjust the video, effect, color, and audio outputs. However, the enhanced results did not stand out in terms of clarity or quality. 

flixier online video resolution enhancer

Our Experience on This Video Resolution 

Unlike the previous video resolution enhancer online,working with Flixier wasn't easy. It required a certain level of knowledge to upload the video clip and work with it as per our requirements. We fine-tuned the controls, tweaked the color, applied effects, and even experimented with the audio output. While our end result had everything in effect, in the free version, we couldn’t find the actual ‘enhancement.’ Overall, maybe upgrading to the pro version yields better results. However, the best part was that, unlike other online tools that offered only a 1-second or 5-second preview, here we could download the full video length without hassle. 

Pros

  • Facilitated bulk video uploads and processing.

  • Gives advanced controls over the exported (enhanced) video.

  • Easy drag and drop functionality for convenience.

  • Heavy controls, effects, and options for customized output.

Cons

  • The editing and enhancement require a bit of technical knowledge for smooth processing.

  • Requires some extent of technical expertise to work with the video clip.

  • The exported video has a watermark logo.

  • The free version does not have visible video enhancements.

  • Requires signing up and account credentials to download the adjusted (enhanced) video clip.

Trustpilot Ratings1.1/5

Supported OS - video resolution enhancer online tool

Fotor is a powerful video resolution enhancer onlinethat can instantly improve video quality. It can quickly enhance low-light videos, tweak sharpness, brightness, and make the footage clearer. Powered by AI, it gives an unparalleled viewing experience in a single click. Supporting MP4, MOV, and WebM formats, you can upload a 5-minute video up to 4K with 60 fps and not exceeding 1 GB.

Speed and Effectiveness Test

Finally, we tested Fotor for its speed and effectiveness. Testing the same clip for all the video enhancer tools, Fotor took over a minute to generate a 3-second video clip. Considering effectiveness, there was barely any visual enhancement in the processed clip. In fact, the 3-second preview clip showed visible noise and distortions. 

fotor video resolution enhancer online

Our Experience on This Video Resolution Enhancer

To be honest, unlike the website claims, working with Fotor was quite a disappointment. It lacked manual controls for personalized and customized output. Plus, the resultant video didn’t seem to undergo any AI transition. The preview video clip had the same video resolution as the original one (256 x 144 px). Even to download the full video in the free version, we were required to spend 100 credits. But it had the exact resolution as the preview clip, with no signs of enhancement anywhere. 

Pros

  • Can be used on any device or platform without any software download.

  • No annoying ads or pop-ups on the website.

  • Simple UI and easy navigation with no unnecessary functions on the homepage.

  • Works with popular video (digital) formats such as MP4, MOV, and WebM.

Cons

  • Takes over a minute to generate a 3-second preview video clip.

  • Requires 100 credits to download the full video (without enhancement).

  • Requires sign-up and account credentials to explore the full functionality of the platform.
