Job applications: Resume uploads often capped at 500KB-2MB
Government forms: Strict limits (200KB-2MB depending on portal)
University submissions: Assignment uploads with size caps
Legal filings: Court systems with document size requirements

How to Compress PDF to Exactly 500KB (Step-by-Step)

Method 1: Direct PDF Compression

Open EverydayPDF Compressor
Select or drag your PDF file
Adjust compression level (higher = smaller file)
Check the output size preview
Download when under 500KB

💡 Compression Tip

If your PDF has many images, you'll see dramatic size reduction. Text-heavy PDFs with few images are already fairly optimized and may not compress much further.

Method 2: For Scanned Documents

Scanned PDFs are often huge (10-50MB) because they're essentially images. For these:

Extract images from the PDF
Compress each image using Image Compressor
Recombine into PDF using Image to PDF

This gives you more control over the final size and quality.

PDF Size Requirements by Platform

Why Privacy Matters for PDF Compression

Think about what's in the PDFs you compress:

Resumes: Your name, address, phone, work history
Bank statements: Account numbers, transaction history
Medical records: Health information
Contracts: Confidential business terms
ID documents: Government IDs, passports

When you upload these to a random website, you're trusting them completely with this data.

⚠️ Real Risk

In 2022, a popular PDF tool was found to be storing all uploaded documents indefinitely. Over 50 million documents were exposed, including tax returns and medical records.

Understanding PDF Compression

PDFs contain several types of data that can be compressed:

1. Images (Biggest Impact)

Most PDF size comes from embedded images. A single high-resolution photo can be 5-10MB. Compressing these images can reduce a 20MB PDF to under 1MB.

2. Fonts (Moderate Impact)

PDFs can embed entire font files. Subsetting (including only used characters) helps reduce size.

3. Metadata (Small Impact)

Author info, creation date, editing history. Usually small but can add up in documents with many revisions.

Frequently Asked Questions

Will compression make my PDF look bad?

For text documents, no visible difference. For image-heavy documents, slight quality reduction is possible at high compression levels. Always preview before sending.

Can I compress a password-protected PDF?

You'll need to remove the password first (if you have it) using PDF Unlock, then compress, then optionally re-add protection.

Why is my scanned PDF so large?

Scanned documents are images, not text. A single page scanned at 300 DPI can be 1-3MB. Use the Image Compressor method described above for best results.

Can I compress PDF on my phone?

Yes! EverydayPDF works on any device with a browser - iPhone, Android, iPad, or computer.
