How to Compress a PDF

Big PDF files can be a hassle — they clog email attachments, fail to upload on portals, and slow down sharing. Compressing your PDF makes it lighter and easier to send, all while keeping your content clear.

Step-by-Step Instructions

1. Open the Compress PDF tool.

2. Drag and drop your file or click to upload.

3. Choose the Recommended setting — it balances file size reduction with image quality.

4. Wait a few seconds while your file is optimized.

5. Download the smaller version of your PDF and check that the text and images still look great.

Why Compression Helps

• Email limits: Most providers cap attachments at 20–25 MB.
• Faster uploads: Smaller files are easier to send on slow connections.
• Storage savings: Light files take less space on your device or cloud.

Pro Tips

• If your file is still too big, try Split PDF to cut it into sections before compressing.
• For scanned files, grayscale reduces file size without hurting readability.
• Combine multiple PDFs with Merge PDF, then compress the final document to keep it email-friendly.
