How to compress a PDF to 500 KB
University, scholarship and visa portals often allow around 500 KB per document, which is plenty for sharp scans if they're compressed well. This page is set to 500 KB and keeps as much quality as the limit allows.
Add the PDF, such as transcripts or bank statements.
Leave 500 KB selected.

What 500 KB is good for
Half a megabyte is a common per-file limit on application systems and document portals, and a realistic size for a complete multi-page scan. Ten to fifteen pages of black-and-white text at 200 DPI usually fit without downscaling, and a colour scan of a few pages keeps most of its quality. It is also a sensible size to aim for when a form has no stated limit but keeps timing out on upload.
As with every preset here, the target is 500,000 bytes and the result note tells you the final size.
Scanned versus typed documents
Typed PDFs contain text as characters, which compress almost to nothing, so a 200-page thesis can be smaller than a two-page scan. If a typed PDF is over 500 KB, the bulk is in embedded images or fonts; the compressor re-encodes the images and leaves the text sharp. Scanned PDFs are images on every page, so their size is roughly proportional to page count, and splitting into parts with Split by Size is the fallback when compression alone is not enough.
