Does not resize PNG image as expected under certain conditions

[zehawki]

Describe the bug
Does not resize an image

To Reproduce
Steps to reproduce the behavior:

1. Go to https://fengyuanchen.github.io/compressorjs/
2. Use the image from https://www.transparentpng.com/download/happy-st-patricks-day-_34433.html
3. Set maxWidth to 1035px or higher
4. Image wont resize

Expected behavior
Should resize to 1035px or higher

Screenshots

Additional context
Any maxWidth < 1035px correctly resizes the image.

This same kind of behavior is seen with different images, with different values of maxWidth. This library is unexpectedly buggy.

For your case, you may need to set the strict option to false.

Nope, there is something really wrong here. I'm trying with another PNG image that is ~3000 x 4000 px. Asking for maxWidth = 2500 blows up the image size massively.

This is why the strict option should be set to true by default, as it is hard to compress PNG images.

For compressing PNG images:

• Set the mimeType option to image/jpeg.
• Or set the convertSize option to a small value.
