How to Compress PDFs Best Practices

1. Select the Right Compression Level: Be aware of the trade-off between file size reduction and quality. A higher compression ratio might degrade the quality of images in the document.

2. Use Dedicated PDF Compression Tools: Software like Adobe Acrobat Pro DC and PDF Squeezer offer advanced optimization techniques to ensure the right balance between file size and quality.

3. Audit Space Usage: Tools like Adobe Acrobat Pro have features to review which elements in the PDF are using the most storage space. This can help you decide where to focus your compression efforts.
4. Choose the Right Level of Compression: It's crucial to determine the level of compression that suits your needs. A maximum compression might offer significant size reduction but could compromise image quality and document quality.
5. Select from a Wide Variety of Tools: Different tools offer varied compression techniques. Whether you prefer Adobe Acrobat, an online PDF compressor, or a tool like Google Drive, ensure the software fits your requirements.
6. Understand Your PDF Content: Before compressing, recognize the file content in your PDF. If it has numerous high-resolution images, you might experience more noticeable quality loss post-compression.
7. Maintain Originals: Always save a backup of your current PDF file before initiating compression. This ensures you have the original content if you need to revert.
8. Utilize File Browsers: When using tools, utilize built-in file browsers to locate and select the exact PDF files you intend to compress.
9. Check Compatibility: If you're looking to create an editable PDF file or convert it to other digital file formats post-compression, ensure the compression tool retains such capabilities without corrupting the file.
10. Ensure File Security: Especially when using online compression tools, prioritize file security. Ensure the platform does not retain your uploaded document or misuse your data.
11. Be Mindful of Image File Formats: Some compressors can alter the format of embedded images. Always double-check to ensure the quality and format of your images remain consistent post-compression.
