PDF File Compressor

Upload a PDF file to reduce its size while maintaining readable quality.

Frequently Asked Questions

The tool reduces file size by downsampling embedded images, removing redundant data, and applying compression to the PDF streams.

Yes. Text is not affected by compression. Only embedded images are downsampled.

Typical reduction is 30 to 70 percent depending on how many images the PDF contains and their original resolution.

Yes. Scanned PDFs contain images, which are the main target of compression. The tool downsamples the images to reduce file size.

Yes. Text content is not affected by compression. The PDF remains searchable and selectable.

Compressing a signed PDF may invalidate the digital signature. Remove signatures before compressing if needed.

Lossless compression reduces size without affecting quality. Lossy compression (image downsampling) reduces size more aggressively but may reduce image sharpness.
