What This Tool Does

It reduces the file size of your PDF. Upload the file, the tool compresses it, and you download a smaller version. The tool shows you the original and compressed sizes so you can see exactly how much was saved.

Processing happens in your browser. Your file does not leave your device.

How to Use It

• Click Choose PDF and select your file.
• The original file size is displayed automatically.
• Click Compress PDF to start.
• Download the compressed file and check the size reduction.

How Much Will It Compress

Results vary depending on what is inside the PDF. Documents with large embedded images compress significantly. Text-heavy PDFs with minimal graphics may see smaller reductions since there is less redundant data to remove.

The tool optimizes the PDF structure and removes unnecessary internal data without altering the visible content. Text remains fully readable and selectable after compression.

Common Uses

• Reducing a PDF before attaching it to an email with size limits
• Compressing a scanned document before submitting it to a portal
• Shrinking large PDFs before uploading to a cloud storage service
• Reducing file size for faster sharing over messaging apps

Frequently Asked Questions

Will the text still be readable after compression?

Yes. Text quality is not affected. Only redundant structural data is removed.

Why is my compressed file almost the same size?

If the original PDF was already optimized or contains mostly text with no images, there is limited data to remove. The tool compresses what it can.

Is there a file size limit?

No server-side limit. Processing happens locally on your device.

Will the layout change after compression?

No. The visual layout, fonts, and structure all remain the same.
