Compress PDF
Reduce PDF file size for email, sharing, or storage. Choose quality-preserving, balanced, or stronger compression; the file never leaves your device.
Smaller files, honest results
Your PDF is processed on your device and is never uploaded by this tool.
- Three clear compression levels for different needs.
- Keeps selectable text, links, forms, and Arabic content.
- Never replaces the original when compression makes it larger.

Computers can use files up to 100 MB; phones and low-memory devices up to 50 MB.
Large PDF: processing stays on this device and can temporarily use several times the file size in memory. Keep this tab open; you can cancel at any time.
Compression level
Balanced works well for most documents. The actual saving depends on how the PDF was created.
Pages are not turned into screenshots. Searchable text, Arabic text, links, and forms remain part of the PDF.

PDF compression FAQ
Is my PDF uploaded?
No. Compression and download happen locally in your browser.
Will Arabic text remain searchable?
Yes. The tool does not rasterize pages, so embedded Arabic and other selectable text remain text.
Why did my file barely shrink?
Many PDFs already contain compressed images and streams. The tool reports the real result and keeps the original if rewriting would make it larger.
Does strong compression reduce quality?
It can reduce the quality of compatible JPEG images. Text and vector content stay sharp; use Preserve quality when visual fidelity matters most.
