When this is useful
An attachment above the email limit
Compress a report with photos so it fits the send.
Forms with a size limit
Sign-up portals usually ask for files of a few MB.
Scanned PDFs
High-resolution scanned sheets become much lighter.
Tips for a good result
- Start with the Balanced option and only raise the compression if needed.
- Plain-text PDFs barely shrink: the weight comes from the images.
What this tool does not do
- If the PDF is only text and vectors, the saving will be small.
- High compression can reduce the sharpness of photos.
Frequently asked questions
- Is the text still selectable?
- Yes. Text, fonts and vectors are not rasterized; only photographic images are recompressed.
- Which option is best?
- Balanced covers most cases; use High quality when the images matter.
