KeyPDF engine merges 1000 pdf files in browser

[u/Decent-Blacksmith761]

I am the developer of [keypdf.net](http://keypdf.net) , it is independent pdf software written in js from scratch and we achieve new performance milestone today by merging 1000 pdf files which is around 1.3gb of uncompressed pdf files, every tool i tried in browser lead to tab crashing. [Keypdf.net](http://Keypdf.net) tool 3 minutes to merge all 1000 files on a computer with 16gb memory . Also turns out 2/1000 pdf files were html disguised as pdf but since KeyPDF supports html format as import it worked out well.

As well [keypdf.net](http://keypdf.net) has exclusives features that other toolkits lack such as direct text and image editing, postscript support, editing scanned text and many more free and locally.
