## How to compress a PDF to 5 MB

1. **Add your PDF.** Drop one or more PDF files onto the compressor above, paste them, or click to browse.
2. **5 MB is preset.** The target is already set to 5 MB, and each file is compressed to land at or just under it. You can switch to another size or a percentage to reduce by.
3. **Compress.** Click Compress. The PDF is processed in an isolated cloud sandbox and deleted afterwards.
4. **Check and download.** Check the new size, then download each file or all of them as a ZIP.

## Good to know

- 5 MB is roomy: most documents keep near-original quality, and only long scanned or image-heavy PDFs need noticeable downsampling.
- That's about 500 KB per page for a 10-page document (photos and scans stay sharp). Text stays selectable at any size; it's the scans and photos that get downsampled.
- 5 MB here means 5,000,000 bytes, a little under the 5,242,880 bytes some sites mean by 5 MB, so the result fits either way.
- PDF files are compressed in an isolated cloud sandbox created just for your job; the upload and the result are deleted automatically afterwards.

## What fits in 5 MB

Spread across the pages, 5 MB gives each page this much room. Text costs very little; scans and photos cost the most.

| Pages | Budget per page | What survives |
| --- | --- | --- |
| 1 page | 5 MB | Photos and scans stay sharp |
| 5 pages | 1 MB | Photos and scans stay sharp |
| 10 pages | 500 KB | Photos and scans stay sharp |
| 25 pages | 200 KB | Scans at good resolution |
| 100 pages | 50 KB | Text pages fine, scans get blurry |

_Rough guide. Text-only pages are often just a few KB each; a scanned page is mostly image data._

## What 5 MB is typically for

- Attaching big PDFs to an email comfortably
- Brochures and slide decks exported to PDF
- Upload forms with a 5 MB cap

Limits vary by site and change over time; check the exact number where you're uploading.

Drop the PDF onto the compressor above. The 5 MB target is already set, so just click Compress and download the result.

### Will the file be exactly 5 MB?

It aims to land at or just under 5 MB. 5 MB here means 5,000,000 bytes, so it also fits sites that count 1 MB as 1,048,576 bytes.

### How much quality will I lose at 5 MB?

5 MB is roomy: most documents keep near-original quality, and only long scanned or image-heavy PDFs need noticeable downsampling. That's about 500 KB per page for a 10-page document (photos and scans stay sharp). Text stays selectable at any size; it's the scans and photos that get downsampled.

### My PDF is already smaller than 5 MB. What now?

Then it already fits, and compressing it further would only cost quality. Upload it as it is, or pick a smaller target if you need it smaller still.

### What if my PDF can't get down to 5 MB?

Long scanned PDFs may not reach 5 MB while staying readable. Split the PDF into parts, or pick a larger size.

### What is 5 MB typically needed for?

Common reasons: attaching big PDFs to an email comfortably; brochures and slide decks exported to PDF; upload forms with a 5 MB cap. Limits vary by site, so check the exact number where you're uploading.
