# Compress a PDF to 1 MB

Job boards, visa and university portals often accept PDFs of only 1 or 2 MB. Pick the limit and the file is shrunk just enough to fit, keeping text selectable whenever it can.

**Quick answer:** To compress a PDF to 1 MB, open it here, keep the 1 MB target (or pick 500 KB, 2 MB or 5 MB) and download the result. Photos inside the PDF are shrunk first so text stays selectable; only if that is not enough are pages converted to images. The file never leaves your device.

## How to use it

1. Choose the PDF: a CV with a photo, a portfolio, a scanned application or a report.
2. Pick the limit the portal states: 500 KB, 1 MB, 2 MB or 5 MB.
3. Press Compress to target.
4. Check the result on the page, then download it and upload it to the portal.

## Why a 1 MB PDF usually keeps its text

In most oversized PDFs the text is only a few kilobytes: the size comes from photos and scans. So the first step shrinks just those images (to about 1400 to 1800 pixels and a lower JPEG quality) and re-packs the file. A CV with a headshot or a report with charts and photos usually lands well under 1 MB this way, with text, links and fonts unchanged, so applicant tracking systems can still read it.

Only scanned documents of many pages need the second step, where pages become images. The result tells you which step was used.

## Common PDF upload limits

| Where | Typical limit |
| --- | --- |
| Job application portals and applicant tracking systems | 1 to 5 MB per document |
| University and scholarship applications | 1 to 10 MB per document |
| Visa and government portals | Often 1 or 2 MB, sometimes 300 KB or less |
| Email attachments | 20 to 25 MB (see [reduce PDF size for email](https://sharelargefilesfree.com/tools/reduce-pdf-size-for-email)) |

Limits are set by each site and change; the upload page itself is the authority. For smaller limits use [compress PDF to 500 KB](https://sharelargefilesfree.com/tools/compress-pdf-to-500kb), [200 KB](https://sharelargefilesfree.com/tools/compress-pdf-to-200kb) or [100 KB](https://sharelargefilesfree.com/tools/compress-pdf-to-100kb).

## If it will not fit

- **Several documents in one PDF?** Many portals have one upload per document: [split the PDF](https://sharelargefilesfree.com/tools/split-pdf) and upload each part.
- **Blank or duplicate pages?** Remove them with [Delete pages](https://sharelargefilesfree.com/tools/delete-pages).
- **Portfolio for a person, not a form?** Send the full-quality original with a [download link](https://sharelargefilesfree.com/) instead, free up to 20 GB.
