    How to Compress a PDF File

    Large PDF files can be a headache — too big for email attachments, slow to upload, and eating up storage space. Our PDF compressor reduces file size by optimizing internal streams and removing redundant data.

    How it works: Upload your PDF and we'll apply lossless compression techniques to reduce the file size. The visual quality of your document stays the same — text stays crisp and images remain clear.

    When to Compress PDFs

    Common scenarios include: reducing PDFs to meet email attachment limits (typically 25MB), optimizing scanned documents that are unnecessarily large, shrinking files for web upload, or saving storage space on cloud services.

    Results vary depending on the original file — PDFs with embedded images typically see 20-60% reduction, while text-heavy PDFs may see 5-20% savings.
