Compress PDF online — free & private

This Compress PDF tool reduces the file size of a PDF directly in your browser. Choose a compression level, optionally fine-tune the image quality, and download a smaller file in seconds. Because everything runs locally on your device, your document is never uploaded to a server, which makes it safe for sensitive files such as scans, contracts, and forms.

The tool works by re-rendering each page and re-encoding it at a lower image quality, which is the most reliable way to shrink a PDF without any server. It is ideal for email attachments, upload limits, and storage savings. For best results on text-heavy documents, choose the Light level.

Frequently asked questions

Is my PDF uploaded to a server?

No. Compression happens entirely in your browser. The file never leaves your device and nothing is stored anywhere.

Why does the text stop being selectable after compression?

To shrink the file reliably without a server, each page is converted to an image. The text remains clearly visible but is no longer selectable. Choose the Light level to keep maximum visual quality.

How much smaller will my PDF get?

It depends on the original. Image-heavy and scanned PDFs shrink the most. The tool shows the exact before and after size so you can see the savings before downloading.

Will compression reduce the number of pages?

No. Every page is kept. Only the visual data is re-encoded at a smaller size; the page count and order stay the same.

Does it work on mobile?

Yes. It runs in any modern mobile browser, though very large PDFs may take longer on lower-powered phones.
