# Compress a PDF to 300 KB

300 KB is a common limit for supporting documents: mark sheets, experience letters, proof of address. It holds several readable scanned pages when the PDF is compressed step by step.

**Quick answer:** To compress a PDF to 300 KB, open it here, keep the 300 KB target and download the result. The tool first shrinks the images inside the PDF and keeps the text; only if that is not enough are pages turned into images at a lower resolution. Three to five scanned pages usually stay readable at 300 KB. Nothing is uploaded.

## How to use it

1. Choose the PDF that is too big for the form.
2. Keep 300 KB, or pick 200, 400 or 500 KB to match the limit.
3. Press Compress to target and wait while it tries the gentlest method first.
4. Check the pages on screen, then download and upload the PDF.

## Pages that fit in 300 KB

| PDF | At 300 KB |
| --- | --- |
| Typed document of any common length | Usually fits, text kept |
| 1 to 2 scanned pages | Sharp |
| 3 to 5 scanned pages | Readable |
| 10 or more scanned pages | Small print gets soft; use 500 KB or split the file |

## Keeps text when it can

PDFs made in Word or Google Docs are mostly text and fonts, which take little space; their size usually comes from embedded photos or logos. Shrinking those images often gets the file under 300 KB with every word still selectable and searchable. Only scans, which are photos of pages, need to be turned into lower-resolution images, and the tool tells you which step it needed.

## If it still does not fit

- Upload fewer pages: [split the PDF](https://sharelargefilesfree.com/tools/split-pdf) if the form accepts several files.
- Make scans grey with [Grayscale PDF](https://sharelargefilesfree.com/tools/grayscale-pdf).
- For a single image, [compress image to 300 KB](https://sharelargefilesfree.com/tools/compress-image-to-300kb) instead.

The PDF is compressed in your browser and never uploaded to us.
