# Resize PDF Files

Resize your PDF to a smaller file size while maintaining document quality and readability.

"Resize a PDF" usually means one of two very different things, so it's worth being clear: this tool reduces a PDF's file size — its weight in megabytes — not its page dimensions. Your pages stay the same physical size; they just take up less space on disk and travel more easily. If you came here to fit a fat PDF under an email or upload limit, that's exactly what this does, by recompressing the embedded images and tightening the file structure until the megabytes drop while the document stays readable. (If you actually need to change page dimensions — say, scale A4 down to A5 or change the paper size — that's a different operation this tool doesn't perform.) For the common case of an oversized scan or image-heavy report, drop it in and you'll get a lighter version back. Everything runs in your browser, so the file is resized down without ever being uploaded, keeping private documents private.

## How it works

1. **Upload PDF** — Select or drag and drop the PDF you want to compress
2. **Optimize** — The tool analyzes and optimizes your PDF structure automatically
3. **Download** — Get your smaller PDF file, ready for sharing or storage

## Use cases

- **Email-Ready Files**: Resize a heavy PDF down so it clears attachment limits
- **Faster Sharing**: Lighten files for quick sending over chat and messaging apps
- **Portal Uploads**: Bring documents under a website's file size restriction
- **Disk Savings**: Reduce the on-disk weight of a growing PDF collection

## Tips

- **It's File Size, Not Page Size**: This shrinks the megabytes, not the paper dimensions. Your pages stay the same physical size.
- **Aim at a Limit**: If you're resizing to clear an attachment cap, check the result against that limit before sending.
- **Images Are the Lever**: Most of the weight is in embedded images, so picture-heavy files resize down the most.
- **Keep the Original**: Save your full-size file in case you ever need the maximum image detail back.

## FAQ

### Does 'resize PDF' change my page dimensions?

No. Here, resizing means reducing the file's weight in megabytes. The page dimensions and layout stay exactly the same.

### How does it make the file smaller, then?

By recompressing the images inside the PDF and tightening its structure, which lowers the file size without altering the visible pages.

### Can I scale my pages from A4 to A5?

Not with this tool — it reduces file size, not paper dimensions. Changing page size is a separate operation.

### Is the file uploaded when I resize it?

No. The work happens in your browser, so the PDF never leaves your device.

## Problems solved

- Confusing file size with page size
- Heavy PDFs that won't attach to email
- Documents over a portal's upload limit
- Large files slow to share or sync

## Stats

- **Megabytes** not page dimensions
- **Readable** pages unchanged
- **Private** in-browser only
