Why compress PDFs to 50kb
PDF files have a way of being larger than expected, even when the content inside is fairly straightforward. A document with a few images, a scanned page or two, or some embedded graphics can quickly grow beyond the file size limits set by email providers, job application portals, or university submission systems. When that happens, you're often left scrambling to find a way to make the file smaller before you can actually send or submit it.
Compressing a PDF to 50KB strikes a good balance for documents that contain a mix of text and images. At that size, you've got enough room to preserve the general look of the document while still keeping it well within the limits of most platforms. Zamzar's online PDF compressor makes it simple to get there: upload your PDF and you'll have a smaller version ready to download in just a few steps. This is particularly handy for things like CVs with a logo or photo, short reports with charts, or scanned documents that you need to send off by email. It's also a practical option if you're uploading files to a shared drive or project management tool where keeping individual file sizes down helps everything run a bit more smoothly.
