Ckeditor5: Base64UploadAdapter: Limit image size

[eleave]

📝 Limit image size (Feature request)

Hi everyone!
I use base64 adapter for images:
https://ckeditor.com/docs/ckeditor5/latest/features/image-upload/base64-upload-adapter.html

I choose a big picture and it converted to base64 string:

And it is very very very big long base64 string :)
It would be useful to add some size limits for image, set max width or max height in configuration

I remember that browsers don't like such large strings and it may occur an error or bad response on submit

That's right. Putting big pictures as base64 encoded images definitely impacts the performance.

you can use this
https://github.com/cristianizzo/ckeditor5-build-classic/blob/stable/src/modules/base64uploadAdapter.js#L84

it resizes the image to 1.5mb, you can change here
https://github.com/cristianizzo/ckeditor5-build-classic/blob/stable/src/modules/imageCompressor.js#L6

I am using document verzion of ck and also using base 64 for image upload.
My editor is getting crash if I upload a large image.
So for that, I was thinking to restrict the user to upload the image of large size just image below 1mb will be allowed to upload in the editor.

So for that, I have added the "imageCompressor.js" as you mention above but seems it's not working or I may have not to implement it correctely. I have set up the built form online of the document version of CKeditor 5.
