Compress PDF
Reduce PDF file size for email, uploads, and client delivery while keeping a result-first comparison before you download anything.
Before you upload
- Works with one `.pdf` file at a time and keeps processing in your browser.
- Best results usually come from PDFs with duplicate structure or inefficient object streams.
- Image-heavy or already optimized PDFs may shrink only a little, or not at all.
What you get
You will see the original size, optimized size, and savings before deciding to download the output file.

- Compression is file-dependent. Already optimized or image-heavy PDFs may not shrink much.
- If savings are minimal, you can skip the download and keep your original file.
Common use cases
- Prepare PDFs for email attachments and approval loops
- Reduce upload size for portals, forms, and client handoff systems
- Check whether a PDF can be made lighter before sending or archiving
Quick FAQ
- Will every PDF shrink a lot? No. Already optimized files or image-heavy exports may only change a little.
- Why show the result before download? Because some files are not worth replacing if the savings are too small.
- Is this a full PDF optimizer? No. It is a practical browser tool for lighter exports, not a complete document editing suite.
