About Compress PDF
Large PDFs are hard to email and slow to share. This tool re-saves your PDF in optimized form, dropping unused objects and duplicate data, which often makes the file smaller without touching a single page.
One honest limit: pictures inside a PDF are not recompressed here, so a PDF that is mostly scanned images may shrink only a little. For documents with text, forms and unused data, the saving is usually noticeable - and the tool always shows you the before and after size, so you can judge for yourself.
How to use it
- Choose your PDF file.
- Press Compress & Download.
- Compare the old and new sizes shown, and keep the smaller file.
Frequently asked questions
How much smaller will my PDF get?
It depends on the file. PDFs with unused objects, duplicate fonts or old edits shrink well; PDFs made of scanned images shrink little, because images are not recompressed in the browser.
Will my PDF lose quality?
No. Pages, text and images are copied unchanged - only the file structure is rewritten.
Is my PDF uploaded?
No. Compression runs entirely in your browser.
