- Compression optimizes images and embedded resources.
- Download the smaller PDF and send it on its way.
Why use this tool

- Text stays sharp and selectable - this is not a screenshot trick.
- Ideal for email attachments, upload forms and slow connections.
- Original quality preserved as much as the compression level allows.
Frequently asked questions
How much smaller will my PDF get?
Image-heavy PDFs often shrink by 70-90%. Text-only PDFs are already small and shrink less.
Will compression damage my document?
Text is untouched. Images are re-encoded at a size that stays readable on screen and in print.
Can I choose the compression level?
A balanced level is applied automatically - it keeps quality high while shrinking the file size noticeably.
Is there a size limit for input?
Every plan accepts files up to 100 MB per file. Pro adds unlimited OCR, batch processing and priority processing.
