Uh hello guys uh welcome to this video.
0:02
So in this video I'll show you I built
0:04
out a react project which allows you to
0:07
edit your PDF files directly in the
0:10
browser. So this is actually a complete
0:12
application that I developed. I'm
0:13
running it on localhost 5173.
0:16
So this is the actual interface of the
0:18
application. So we have actually have
0:21
this button here. You simply click this
0:23
button to select your PDF document. So
0:27
once you select your PDF document, it
0:29
will load all the pages inside the PDF
0:32
file here. As for example in this it
0:34
contains two pages. So it actually loads
0:37
both the pages in the PDF document. You
0:39
can actually read the PDF file directly
0:41
in the browser. And now we also have the
0:44
option to actually highlight and
0:47
annotate the PDF file. We have various
0:50
options. We can either add text, images,
0:53
we can highlight everything. So let me
0:56
show the option one by one. So if you
0:59
need the source code of this application
1:01
guys, I've given the link in the
1:02
description. You can directly purchase
1:04
the full source code. So this will be
1:07
the directory structure you will get.
1:09
This is will a complete react project.
1:12
Each and every component is divided into
1:14
its appropriate TypeScript file here. As
1:16
you can see, I basically coded this
1:19
project from scratch. So I'm selling
1:22
this source code. I have given the link
1:24
in the description of the video. So
1:27
for the demo, I'm running this project
1:30
locally on my system npm runep. So after
1:34
you purchase it, it's very easy to run
1:36
the system lo to run this project
1:39
locally or also you can deploy this to a
1:41
domain name as well. So now after that
1:44
we can actually
1:46
click the add text button. As I click
1:49
it,
1:50
you can basically
1:53
add the text in the PDF file and you can
1:57
even control various properties as well
2:00
such as you can change the color of the
2:02
text as well.
2:04
Here you can even control the size of
2:07
the text as well and then you can using
2:10
the select tool you can actually place
2:12
the text accordingly wherever you need
2:14
to place the text. After you are happy
2:16
you can go to the next page. Now in the
2:19
next page, let's suppose you want to add
2:21
a image. You also have the support here
2:23
to add an image, insert image. So right
2:27
here you can actually search for your
2:30
file
2:32
and then after you selected your file,
2:35
you can click on insert image and then
2:38
you can control actually the size of
2:40
this image and just place it accordingly
2:43
wherever you want to play place it
2:45
inside your PDF file. just place it. And
2:49
then we also have the support for adding
2:52
different kinds of shapes.
2:55
You can actually do this. And then we
2:58
also have the pen button where you can
3:01
actually highlight anything
3:05
just and here you can even change the
3:08
color here.
3:13
So here you can actually
3:16
highlight something or annotate
3:18
something. It's very easy. You can see
3:20
how easy it is. Just you need to
3:26
place your mouse and then automatically
3:29
it will be highlighted. And then you can
3:31
even put your signature as well.
3:34
Just click signature. You can upload
3:37
your signature by using an image or you
3:40
can draw your signature manually. So you
3:42
can even using your mouse you can draw
3:45
your signature and just click insert
3:48
signature and then you can place your
3:51
signature accordingly.
3:53
So after that you can click
3:56
the export go to the file menu export
4:00
and then you can export this to a image
4:03
file.
4:05
You can individually select which page
4:07
you want to export or you want to export
4:10
all the pages and just select PDF and
4:13
click on export and after that the PDF
4:16
will be exported and then here you can
4:18
save your PDF file accordingly wherever
4:20
you need to save it and now you can see
4:23
that my PDF has been successfully
4:26
downloaded with all the changes that
4:27
I've done such as the highlighted
4:31
annotation everything addition of text,
4:34
images, every result has been reflected.
4:37
So this is a complete PDF editor I
4:40
developed in ReactJS and I'm selling the
4:43
source code. If you are interested in
4:45
this, you can directly purchase it. The
4:47
link is given in the description. So
4:49
once you purchase it, you will get all
4:51
this source code and you will be able to
4:53
see how I coded this project from
4:55
scratch
4:57
and it is very easy. I basically code it
5:00
in such a way that you will not find any
5:02
sort of difficulty in understanding the
5:04
code. It's really easy to understand.
5:06
And let me show you the package.json
5:09
file here.
5:10
And if you still face any sort of error,
5:13

5:15
help you. So we are using some third
5:18
party libraries which are PDF lib, PDFJS
5:22

5:25
libraries that we are using. PDF lib is
5:27
a very popular JavaScript PDF generation
5:30
library and same goes with PDFJS disc
5:33
library as well. These two are external
5:36
libraries but they are completely free

and we are using the latest React
5:42
version and we are also using React PDF
5:45
as well. React PDF as well which is
5:48
again a PDF generation library. So these
5:51
are quite a number of packages that we
5:54
are using. So you will basically
6:00
be if after getting the source code you
6:03
will be able to if you are know the code
6:07
you can modify the source code and add
6:10
