Compress PDF files for upload and email
Use this PDF compressor when a PDF is too large for email attachments, form uploads, or document portals.
Compression depends on the PDF content. Some PDFs are already optimized, while image-heavy PDFs usually have more room to shrink.
Common uses
- Reduce PDF attachments before sending email.
- Make scanned PDFs smaller for upload limits.
- Try browser-based PDF compression before installing software.
How to use it
- Choose one PDF file.
- Pick the compression level.
- Compress and download the result.
Will text remain selectable?
Some stronger compression modes may rasterize pages, so text may no longer be selectable.
Are my files uploaded?
No. Supported tools process files inside your browser and do not upload them to this server.
Is this tool free?
Yes. No login, payment, or membership is required.
Can I use it on mobile?
Yes. Tool pages use a single-column layout and card results on small screens.
