Best screen shot saver out there; does what awesome screenshot will not! Can take far larger screenshots than all the other extensions I used. Doesn't pick up repeating scrolling garbage bars on websites that Awesome Screenshot does.

Screenshot is cut into pieces of 30000 pixels height each. Why? PNG size limit is beyond 2000000000 pixels. But may be a great option if there is another practical limit.

But it doesn't stitch together the screenshot seamlessly. All of the document can be read, but there is a visible line every something-hundred pixels.

It works great but the size of page that it will save is limited. To save longer pages you will need to reduce the zoom of the page.
For saving a screen size image it's ideal.
For example at %100 zoom on google images it saved down to 15 images. when changing the zoom to %50 it saved down to 37 images, those were very poor quality and the text unreadable.
The normal 'Save Entire Page' (going by how many images were shown on the normal screen size was four) is just short of X4 of the normal screen.
That's what I've found using it on Linux, I haven't used it on Windows so the performance may be better for Windows.
Update,
I still haven't found an easier or more reliable page saver, even when the page is too large to save as a single image, the page will be saved with two images.

Simple but effective extension. Very useful to have a header and footer for url and timestamp ! Its only missing 2 features : a capture of selected area and maybe some formatting capabilities for headers and footers (like change font style and size). Works fine on Linux.

One of the Best!

its not saves entire page ...

does not scroll SPAs

This is the ONLY webpage screenshot tool that's capable of handling huge shots, because it splits up really big ones. All the other tools screw things up and either don't grab the whole thing or just give blanks.

User friendly! Awesome!

Very useful tool when I'm researching my family tree because it enables me to quickly take a screenshot of an entire transcript of a document.

I've been trying a bunch of screenshot tools hoping to find one that is capable of grabbing a huge page. None of them could. Sadly, this one couldn't either, but it came closest. It split the page into two images, which I could easily join together myself, but the first one turned out to be empty. Either way, it's very easy to use, and is really fast too. Hoping this one little bug can be fixed in the future.

Update: the quick fix sent to me by the developer worked great (gfx.max-alloc-size = 600000000). It's perfect now.

Considering the fact that Firefox has gone full SJW and will NOT let you use it"s capture on certain websites this will work just fine.

I tested many other apps that claim to be able to capture a whole webpage and none could do the job. This one does flawlessly! Thank you very much!

Was pulling my hair trying to get web pages into pdf. All the pdf addons SUCK. So... I'm using this to create a jpg. I then use a script to convert the jpg into a pdf (via magick) and then OCR it (via ocrmypdf). Works perfect!! Sent the developers a donation! Thanks. :)

To the developer:
In outlook.com, if you read an email whose bottom part you have to scroll down, using this addon Page Screenshot, it will screenshot the whole VISIBLE AREA but not the NOT VISIBLE PART that is seen only when you scroll down your email.
What I wanted was an addon that would allow me to get a screenshot in jpg or pdf of not only the visible part of the email but especially also the not visible part of the email that is accessible only when you scroll down to see it.

Therefore, I cannot use this addon because it does not do what its title says "Page Saver WE screenshot capture tool". The title should be "Screenshot of Only the visible part of the Web Page".

i tested many, and in case of long long pages, they were only grabbing part of the screen. this extension, however, is able to grab long long page. if the page is too long it will save several files. but it will get everything.

Nice tool...however sometimes the entire page do not work on javascript pages...
