About Compress PDF
Shrink supported photographs inside a PDF without turning its text into pictures. Text, fonts and masks remain untouched, while unsupported image types are skipped. Documents containing mostly text may have little to reduce. If the rebuilt PDF is not smaller, the original is returned.
Compress PDF runs locally without uploading your selected file or requiring an account. Although file selection allows up to 1 GB, available device memory can limit this particular task.
