# PDF247 Compress PDF

> Compress a PDF online with clear, balanced, or smaller output. Pages are processed locally in your browser without file uploads.

PDF247 reduces size by rendering and re-encoding every PDF page at one of three quality levels. Page dimensions stay unchanged, and the original file is kept when compression provides no saving.

## How to use it

1. Choose or drop one PDF up to 200 MB. A document password can be entered locally when needed.
2. Choose Clear, Balanced, or Smaller according to your sending or upload limit.
3. Compress, compare the before and after sizes, and download the resulting PDF.

## Features and limitations

- Three levels trade image detail for file size: Clear, Balanced, and Smaller.
- Page dimensions are preserved, and the original PDF is used when the new file is not smaller.
- Pages are rasterized, so searchable text, links, forms, and vector structure are not retained.
- Each PDF may be up to 200 MB and is processed in the browser without a file upload.

## Frequently asked questions

### Does PDF compression affect clarity?

It can. The tool lowers page image resolution and encoding quality. Clear keeps more detail; Smaller is intended for stricter file-size limits.

### Can I still search or copy text?

Not reliably. Current compression turns each page into an image, so searchable text, links, forms, and vector content are not preserved.

### Why did my PDF not get smaller?

An already compressed, short, or mostly simple vector PDF may offer no saving. PDF247 keeps the original rather than returning a larger file.

### Is the PDF uploaded for compression?

No. Reading, rendering, re-encoding, and PDF generation take place in the current browser.
