How Compress PDF works
Choose Low to preserve PDF features where possible, or confirm Balanced or High raster compression when a smaller image-based copy is acceptable.
Supported formats
Input: PDF. Output: a smaller PDF when reduction is possible, otherwise the unchanged original.
Privacy and limitations
Processing stays in this browser; the selected document is not uploaded to WriteCareerly or an external document service. No method can shrink every PDF. Raster modes remove searchable text, vectors, forms, links, signatures, annotations and accessibility data. Always review the downloaded result.
Compress PDF questions
Why did the size stay the same?
The source may already be optimized or contain little image data. The tool returns the original instead of claiming a false reduction.
Which mode keeps selectable text?
Use Low Compression. Balanced and High rasterize pages and therefore remove text selection.
