想必大家平时和图片打交道时,多少会遇到一些棘手情况,比如说去水印啦,像素太低等等。今天就给大伙儿推荐三个在线小工具,可以无损放大图片,可以一键去掉照片不需要的元素,还可以让黑白照变成彩色。

1、无损放大

有时咱们会遇到那些尺寸很小的图片,等你想放大看清一点,就会发现,整张图片都糊了。

这个时候咱们不妨试试无损放大的在线网页Bigjpg。

先来看看效果,这是一张像素 71x72 的狗头。

如果你单纯地放大,就成了这样。

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)

看看最终放大后的效果,是不是清晰了很多。

这个网站依靠了深度卷积神经网络,将噪点和锯齿的部分进行补充,来实现图片的无损放大。

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。

其实到这个分辨率了,应该也不用放大了吧……

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。

2、老照片修复

在很多年之前,照片都是黑白的。

想必差友家里都存了一些长辈的老照片,有没有想过把它们还原成是彩色。

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……

所以又去找了另外一款能免费用的工具。

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。

这是上色后的效果。

有一说一,效果图出来后,我还是挺惊讶的。

人的肤色、服装以及背后的瓦房、树木,颜色都非常真实。

而且它居然自动把清晰度加了几倍,然后就被林徽因给美到了。

但看到泰戈尔时,差点没崩住,像是橡皮泥捏出来的……不过情有可原,原图里泰戈尔确实太糊了,对智能算法来说难度确实太大了点。

此外,这个网站还可以修复破损,划痕的老照片,甚至是让照片变成动态的。

不过这些需要开会员,有需求的差友们可以考虑氪金一下。

3、去除照片里不必要的元素

相信大家平时都会遇到一张本来挺好的照片,但里面掺进了一些多余的元素,可烦人了。

你想把他们去掉吧,就要把它线条勾出来抠掉,再补上背景。

但这一步,首先你得会 PS 不说,最主要的是麻烦、耽误时间。

今天给大家推荐这个网站,可以一键去除照片里不需要的元素。

比如我们想去掉这个大灯泡招牌。

只需要上传照片,把招牌涂满,等待七八秒。

然后招牌就这么没了……

别说这玩意抠得还挺逼真,看这玻璃,像是有人直接把招牌搬走了一样。

另外,它也可以快速去除一些简单的水印。

试了几个,效果都还行。

比如你在差评君微博看到这只丑丑的修勾火锅,很想要来做表情包,但是有水印。

我们把水印涂满后,松开鼠标,就发现水印消失了,火锅的毛发和草地也自动补了上来。

或者你想改个文案,也可以继续涂抹。

对比下前后效果,就像是原图有没有?

当然了,这种基于 AI 算法的工具,肯定会有智障的时候。

遇到一些复杂的,它就顶不住了,我们可以多涂抹几次试试。

注意,网站有时会遇到无法下载的情况,可以换个时间再看看。

可能有小伙伴发现,有些工具之前我们介绍过类似的。

确实,但是他们要么收费太贵,要么关闭了。

比如消除元素的,之前介绍过 MagicEraser

,但他现在免费版只能下载 600 px 的图片,原图版得10美元/月。。

但你又不能不让人家收费,不然哪来资金持续运营下去。

只能说,现在免费又好用的工具太难找了,所以各位差友接受我们推荐付费工具吗……

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 71x72 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.

Web site:

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.

Web site:

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

has been introduced before, but now he can only download 600 px images for free, and the original version costs $10 a month.

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?
