Which PDFs Can Get Smaller?
This web version repackages the PDF structure. An already optimized document may shrink only slightly. Reducing large scans and photos substantially also requires adjusting image resolution and quality.
Stronger Compression for Business Email
The Windows application includes Balanced, Strong and For Email options. Enter a target such as 3 MB to try progressively stronger compression. The achievable size varies: check both the output size and the readability of small text.
This web version repackages the PDF structure; it does not reduce the resolution of scanned images. Balanced, Strong, For Email and target MB options are in the Windows application.
Frequently Asked Questions
Will every 20 MB PDF become 3 MB?
No. The result depends on page count, images and existing compression. A target size is a processing goal, not a guarantee.
Is my original overwritten?
The browser tool downloads a separate output. Keep the original and inspect the downloaded pages before using the result.
