Drop the PNG into the panel above and press Compress. Your browser re-encodes the file locally and reports the exact before and after size. Note that PNG is a lossless format, so there is no quality setting that trades detail for a smaller file: a re-encode mainly strips metadata and only sometimes saves a meaningful number of bytes.
No. PNG stores pixels losslessly, so a quality factor does not shrink the file the way it does for JPEG. To remove real bytes, resize the image to fewer pixels, or convert it to WebP instead.
No. Decoding and re-encoding both happen inside your own browser using the Canvas API, so the file never leaves your device and there is no server-side copy to delete.
There is no artificial limit because nothing is uploaded; the only ceiling is your device memory. Very large images take longer to decode, that is all.
