## Answer

Drop your PDF into the compressor below. It’s pre-set to 4,882 KB so the file stays under 5 MB by either kilobyte definition. Most text documents and many multi-page scans fit with little or no quality loss. Use this when a course portal or client asks for “under 5 MB”.

## What fits comfortably

Most text PDFs unchanged, or a long scan of thirty-plus pages at good quality.

## What is squeezed

Very large photo-heavy bundles at lower DPI if needed.

## Context

5 MB is a common assignment and LMS limit, and a practical target when emailing a multi-page pack without hitting Gmail’s much larger 25 MB ceiling.

If Keep text already lands under 5 MB, stop there — Target size is only needed when the file is still oversized.

## Tips

- **Try Keep text first** on the main [Compress PDF](https://mypdf.space/tools/compress) tool if you are not sure you need Target size.
- **Split huge bundles** with [Split PDF](https://mypdf.space/tools/split) when the portal allows multiple uploads.
- **Remove blank pages** before compressing so you do not burn the budget on empty sheets.

## FAQ

### How do I compress a PDF to under 5 MB?

Use this page. The compressor is pre-set just under 5 MB, tries a lossless pass first, then lowers resolution only if needed.

### Is 5 MB enough for email?

Yes for most personal email. Gmail’s advertised cap is 25 MB; 5 MB is a safer everyday target when you want a smaller attachment.

### Does this upload my assignment?

No. Compression runs entirely in your browser.
