How to reduce a PDF file size
Start with Keep original quality to optimize file structure without resampling images. Compare actual output sizes and page previews. Stronger settings rebuild pages as images and remove searchable text, links and fillable fields.
- Choose the PDF you want to make smaller.
- Select a quality setting and, if needed, a maximum file size.
- Update the preview, inspect small text using detail zoom, and download the result.
Will the result always meet my chosen size limit?
The tool checks the actual output size, but some documents cannot fit the chosen limit. Choose a larger limit or fewer pages. Keep original quality retains text and form fields; stronger compression may reduce visible quality. If compression would make the file larger, the original is retained.
