I’m trying to upload a PDF to a website, but the file is almost 10MB and the site only allows PDFs under 5MB. Is there a way to compress the PDF without losing too much quality? I need a quick solution since I’m on a tight deadline.

You can refer to this guide: Compress a PDF in Preview on Mac - Apple Support
I have also used Preview to compress files before. It sometimes works well, but sometimes the exported file is even larger than the original.
You can use an online PDF compressor if your files are not private and you only need to convert a few files. There are many good online tools on Google that you can try. If you often compress files and are afraid of the risk of information leakage, it is more recommended to use an offline PDF compressor such as adobe and cisdem.
How much size can be compressed depends on how much useless data there is in the file. I’m not an expert, so I can’t dive into all the technical details. If you’re looking for better compression, you might need to try a PDF product like Adobe, or PDFgear if you need a free one just to compress that PDF.
Thanks for the guide. But unfortunately, the file is about 6MB after compressing with Preview, so I still can’t upload it.
I can't say no when there's a free choice, and PDFgear compressed my file to 4MB, which is able to be uploaded now. Thank you for the help.
If the file is still over 5MB, try re-compressing with a slightly higher compression setting or cropping unnecessary pages/images.
