Is this tool really free?

Yes! This tool is completely free to use. No signup required, no watermarks added, and no hidden fees. Perfect for occasional use.

Do you store my files or data?

We take privacy seriously. Files are processed in real-time and are not stored on our servers. Generated PDFs are stored for 1 day and deleted permanently after that.

Is there a file size limit?

For the free tool, we support files up to 20MB in size. For larger files or batch processing, check out our API plans.

How can I automate this process or use it in workflows?

To use this tool in automated workflows, integrations, or at scale, you'll need to subscribe to one of our plans. Our API allows you to integrate PDF compression into your applications, workflows, and automation tools like n8n, Make, or Zapier. Check the main pdf noodle site for pricing and API documentation.

What compression levels are available?

We offer three compression levels: Low Compression (best quality, ~15-25% reduction), Medium Compression (balanced quality and size, ~35-50% reduction), and High Compression (maximum compression, ~55-75% reduction). Choose based on your quality and file size needs.

Will compression affect PDF quality?

Compression may reduce image quality depending on the level chosen. High Compression provides the most file size reduction with some quality loss, while Low Compression maintains the best quality with minimal reduction. Medium Compression offers a balanced approach.

Can I compress PDFs with text and images?

Yes! Our compression tool works with all types of PDFs, including those with text, images, forms, and annotations. The compression algorithm optimizes both text and image content.

How much can I reduce the file size?

Compression results vary depending on the original PDF content. PDFs with large images typically see the most reduction (often 30-70%), while text-heavy PDFs may see smaller reductions (10-30%).

How do I compress PDF under 50kb?

The final file size depends on your initial PDF size, as each compression level removes a percentage of the original size: Low Compression (~15-25% reduction), Medium Compression (~35-50% reduction), and High Compression (~55-75% reduction). You should try High Compression first for maximum reduction. If your PDF is still above 50kb after compression, try removing unnecessary pages or images before compressing, or use High Compression again on the already-compressed file.

How do I compress PDF under 100kb?

The final file size depends on your initial PDF size, as each compression level removes a percentage of the original size: Low Compression (~15-25% reduction), Medium Compression (~35-50% reduction), and High Compression (~55-75% reduction). You should try High Compression first for maximum file size reduction. If your PDF is close to 100kb, Medium Compression may also work while maintaining better quality. Experiment with both levels to find the best balance.

How do I compress PDF under 200kb?

The final file size depends on your initial PDF size, as each compression level removes a percentage of the original size: Low Compression (~15-25% reduction), Medium Compression (~35-50% reduction), and High Compression (~55-75% reduction). You should try Medium Compression first for a balanced approach between quality and file size. If your PDF is significantly larger, switch to High Compression for more aggressive reduction. PDFs with many images typically compress well and can easily reach under 200kb.

How do I compress PDF under 300kb?

The final file size depends on your initial PDF size, as each compression level removes a percentage of the original size: Low Compression (~15-25% reduction), Medium Compression (~35-50% reduction), and High Compression (~55-75% reduction). You should try Medium Compression first, as it usually works well for most PDFs while maintaining good quality. For larger files or PDFs with many high-resolution images, try High Compression to achieve more significant size reduction. Experiment with different compression levels to find the best balance for your needs.
