Free Tools › Compress PDF
Make big PDFs small enough for email, visa portals and job applications. Pick a level and download.
- ✓ Runs in your browser: your files are never uploaded
- ✓ 3 compression levels
- ✓ Greyscale option
How it works: each page is redrawn as an optimised image inside a new PDF. This shrinks scanned and photo-heavy PDFs the most. Text in the new file is not selectable, so keep your original if you need to copy text.
How to use the Compress PDF
- Choose the PDF you want to shrink.
- Pick Strong, Recommended or Light, and colour or greyscale.
- Tap Compress PDF. You will see the old and new size before it downloads.
Works best on scanned documents and PDFs full of photos, which is where most oversized files come from. Each page is redrawn as an optimised image, so text in the new file cannot be selected. Keep the original if you need to copy text.
Frequently asked questions
How much smaller will my PDF be?
Scanned and photo PDFs often shrink a lot; text-only PDFs may not shrink. The tool shows the exact result and will not hand you a bigger file.
Will the quality drop?
Strong gives the smallest file with softer images. Light keeps quality high.
Is it safe for passport and ID card copies?
Your file is processed on your own device and never uploaded.
