PDF files are widely used in daily work and study, but file size often becomes a problem. This article will help you fully understand and handle PDF file size issues from three aspects. Continue reading to find out the answer.
What Factors Affect the Size of a PDF File?
Understanding the main factors affecting PDF file size will help you manage and compress files more effectively.
- PDFs contain a large number of images: PDF files containing many high-resolution images are generally much larger than plain text PDFs.
- PDFs are scanned documents: Scanned PDFs are usually larger than plain text PDFs because each scanned page is an image, not text.
- PDFs contain embedded data: Additional content embedded in PDFs, such as annotations, forms, audio, or video, also increases file size.
- PDFs are in color mode: Color PDFs are generally larger than black-and-white or grayscale PDFs. This is because color images require recording data across multiple color channels, typically resulting in more than three times the data volume of grayscale images.
Why Do You Need to Resize PDF Under 100/200/300/500KB?
Large PDF files can be inconvenient in daily use, so in many cases it’s necessary to compress them to 100KB, 200KB, 300KB, or 500KB or less. The main reasons are:
- Email attachment limits: Most email services have size limits on attachments. For example, Gmail allows a maximum attachment size of 25MB. Excessively large PDF files may not be able to be sent or uploaded.
- Faster uploads and downloads: Large files take longer to upload to websites or cloud storage, and downloads also take longer.
- Storage limitations: For devices with limited storage capacity, large files can easily fill up storage space. Compressing PDF files can save storage space.
- Platform compatibility: Some online platforms, recruitment websites, or certain work environments have size limits on uploaded PDF files.
