Compress PDF

Reduce PDF Size Efficiently

Our tool helps you shrink large PDF files by recompressing pages at a selectable quality level and resolution. By adjusting these specific parameters, you can significantly decrease the file size while maintaining acceptable visual quality. This process is ideal for documents containing many images or high-resolution scans. Because the compression happens automatically based on your chosen settings, it provides an easy way to make large files manageable for email attachments or web uploads.

Secure Local Processing

Your privacy is our priority. Unlike many online tools that require you to upload documents to a remote server, our PDF compressor works entirely within your web browser. This means the file never leaves your device during the compression process. By processing data locally, we ensure that sensitive information remains private and secure at all times. You can compress your files with complete peace of mind knowing that no third party ever accesses your data.

Optimized for Scanned Documents

This tool is specifically designed to optimize image-heavy documents and scans. During the compression process, pages are rasterized to reduce their size effectively. Please note that once a PDF is rasterized, the text will no longer be selectable or searchable. If your primary goal is reducing the file size of a scanned document or a presentation with many graphics, this tool provides an effective solution while maintaining the visual integrity of your original content.

Is it safe to use this online PDF compressor?

Yes, your data is completely safe because the compression happens locally in your browser. Your files are never uploaded to a server or shared with third parties. The process stays on your device, ensuring that sensitive information remains private and secure throughout the entire operation.

Can I still select text after compressing the PDF?

Because the tool uses rasterization to reduce file size, text will no longer be selectable or searchable after compression. This method is specifically optimized for image-heavy PDFs and scanned documents where reducing the overall file size is the primary goal for easier sharing.

How can I get the smallest file size possible?

To achieve the smallest size, you can lower the quality and resolution settings in the tool. If the initial result is still too large, try reducing these values further. This allows for more aggressive compression of images and graphics within your document to meet specific requirements.

Why does it say my file is already highly compressed?

If you receive a message stating no savings were made, it means the PDF is already optimized. To achieve a smaller size in this case, try lowering the quality or resolution settings further to force a more aggressive compression of the image data.
