先来看看效果，这是一张像素 71×72 的狗头。
但如果把图片上传到 Bigjpg 后，选择放大效果为 4 倍。
等待一会儿。（说是 5 分钟，其实只用了 10秒钟）
网站免费使用，不过你想放大更多倍数，比如 8、16 倍就得开会员了。
觉得平时 4 倍也够用了。
另外免费版的上传图片也有大小限制，在 5M，3000x3000px 以内。
此外这个工具还提供 Windows、Android、iOS、macOS 的客户端，大家有需要也可以下载。
我们在 3 年前给大家推荐过一个老照片上色网页，但就在前几天准备用的时候，发现它在 2020年就已经停止运营了……
下图是 1924 年，泰戈尔访问中国，林徽因、泰戈尔、徐志摩三人留下了的珍贵合影。
但这一步，首先你得会 PS 不说，最主要的是麻烦、耽误时间。
当然了，这种基于 AI 算法的工具，肯定会有智障的时候。
1. Lossless amplification
Sometimes we come across those very small pictures, and when you want to enlarge and see clearly, you will find that the whole picture is burned.
At this time, we might as well try a lossless enlarged online web page & nbsp;Bigjpg.
Let’s take a look at the effect first. this is a pixel 71×72 dog’s head.
If you simply zoom in, it’s like this.
But if you upload the picture to Bigjpg, choose a magnification of 4 times.
Wait a minute. (& nbsp; says it takes 5 minutes, but it only takes 10 minutes nbsp; seconds)
See if the effect after the final magnification is much clearer.
This site relies on a deep convolution neural network to supplement noise and jagged parts to achieve lossless magnification of the image.
The website is free to use, but if you want to magnify more times, for example, 8 or 16 times, you have to open a member.
I think four times as much as usual is enough.
In addition, there is also a size limit for uploaded images in the free version, which is less than 3000x3000px at 5m.
In fact, at this resolution, there should be no need to zoom in.
In addition, this tool also provides Windows, Android, iOS, macOS clients, you can also download if necessary.
2. Restoration of old photos
Many years ago, the photos were all black and white.
You must have saved some old photos of your elders at home. Have you ever thought of restoring them to color?
We recommended an old photo coloring page to you three years ago, but just a few days ago, when we were ready to use it, we found that it had ceased operation in 2020.
So I went to find another free tool.
The picture below is a precious group photo left by Lin Huiyin, Tagore and Xu Zhimo during Tagore’s visit to China in 1924.
This is the effect of coloring.
One by one, I was surprised when the effect map came out.
People’s skin color, clothing, as well as behind the tile houses, trees, colors are very real.
And it unexpectedly automatically increased the clarity several times, and then it was beautiful by Lin Huiyin.
But when I saw Tagore, I almost didn’t collapse, like it was made of plasticine. However, it is understandable that Tagore in the original picture is really too thick, and it is a bit too difficult for intelligent algorithms.
In addition, the site can also repair broken, scratched old photos, or even make them dynamic.
However, these need to open members, there are needs of friends can consider krypton gold.
3. Remove unnecessary elements from the photo
I believe that everyone will usually come across a good photo, but it is mixed with some superfluous elements, which is annoying.
If you want to get rid of them, you have to tick out the lines and scratch them out, and then fill in the background.
But this step, first of all, you have to PS do not say, the most important thing is trouble, delay.
Today, I recommend this website to remove unwanted elements from photos with one click.
For example, we want to get rid of this big light bulb sign.
Just upload the photo, paint the sign all over, and wait seven or eight seconds.
And then the sign just disappeared.
Not to mention that this thing is quite lifelike, look at the glass, it looks like someone has directly removed the sign.
In addition, it can also quickly remove some simple watermarks.
I tried a few, and the results were all right.
For example, when you see this ugly hotpot on Weibo, you really want to make a meme, but there is a watermark.
After we smeared the watermark full, we released the mouse and found that the watermark had disappeared and the hair and grass of the hot pot were automatically mended.
Or if you want to change a copywriter, you can continue to apply it.
Compare the effect before and after, just like the original picture, do you have it?
Of course, this tool based on the AI algorithm is bound to be mentally retarded.
When we encounter something complicated, it can’t stand it, so we can try it a few more times.
Note that sometimes the website cannot be downloaded. You can take a look at it another time.
Some partners may find that there are some tools that we have introduced similar before.
Yes, but they either charge too much or turn it off.
For example, to eliminate elements, MagicEraser
But you can’t help but let others charge, otherwise there is no way to keep the funds running.
It can only be said that now free and easy-to-use tools are too difficult to find, so do you accept our recommended paid tools?
