About Compress PDF
Most oversized PDFs are heavy because of the images inside them, not the text. Compression re-encodes those images at a lower quality so the file fits an email limit or an upload form.
How to use it
- Upload the PDF you need to shrink.
- Pick a compression level — low, medium or high.
- Download the smaller file.
Worth knowing
Compression is lossy and cumulative: compressing an already-compressed file mostly costs quality rather than size. Always start from the original when you can.
Common questions
- How much smaller will it get?
- It depends entirely on the contents. Image-heavy scans can shrink dramatically; a text-only PDF may barely change.
- Will the text stay sharp?
- Text is stored as vectors and is not degraded. Photographs and scans are where the loss shows.
