What actually happened?

ERROR in node_modules/pdf-lib/ts3.4/cjs/api/form/PDFDropdown.d.ts:400:38 - error TS2502: 'provider' is referenced directly or indirectly in its own type annotation.

What did you expect to happen?

Speculation is that the merge error is caused by the TS version being too high

How can we reproduce the issue?

Merge individual PDFs into one PDF

"pdf-lib": "^1.17.1", "typescript": "3.4.3", "rxjs": "6.4.0", "@angular/core": "8.2.14",

I recently encountered a requirement to compress PDF files to below 4M? What should I do?
Please provide a complete example of using it on the browser side.
For example, can you specify the maximum compression value and compression quality?
