# Compress PDF to 500KB.

Make a PDF smaller for 500KB upload limits with smart compression, page trimming, and output size preview.

For half-megabyte limits, Medium often keeps the file clear while High gives you a smaller fallback if the upload still fails.

## Target

500KB target

## Example Result

- Original: 3.2 MB
- BitePDF output: 480 KB
- Saved: 85% smaller

## Why This Workflow Works

- Medium mode for balanced quality and size
- High mode for last-mile file limits
- Side-by-side size result
- Merge, extract, sign, and erase in the same workspace

## How To Use It

1. Drop the PDF into the page.
2. Review the automatic Medium result.
3. Switch to High only if the target is still missed.

## Good For

- resume uploads
- client forms
- online submissions
- small email attachments

## Questions

### Does BitePDF show the compression result before checkout?

Yes. BitePDF shows original size, output size, and saved percentage before you choose an export plan.

### Can I change compression strength?

Yes. The compression picker lets you choose Low, Medium, or High. Low favors quality, Medium balances quality and size, and High targets the smallest export.
