How to Use the PDF Compressor
Upload a PDF, choose the available compression option and create a smaller copy for easier sharing or storage.
Practical Example
A 12 MB presentation PDF may be reduced to a smaller file when it contains large embedded images that can be recompressed.
Factors That Affect the Result
Image resolution, embedded fonts, vector graphics, existing compression and document complexity determine how much file size can be reduced.
Frequently Asked Questions
Will compression reduce quality?
It can, especially when image resolution or quality is lowered.
Why might a PDF barely shrink?
Files that are already optimized or mostly text/vector content may have limited savings.
Does compression change the page count?
No, normal compression should preserve the document’s page structure.
