Shrink your PDF size for easy sharing by email, WhatsApp, or uploading to websites. Choose your compression level and download the smaller file instantly.
Drag and drop or browse to select the PDF you want to compress.
Select Low (best quality), Medium (balanced), or High (smallest size).
Click "Compress PDF" and save the reduced file.
Image-heavy PDFs often shrink 50-80%. Text-only PDFs may only reduce 5-15%.
The tool re-renders pages as JPEG images, so text becomes part of an image. For text-only PDFs, reduction is minimal.
"Medium" is best for most cases. Use "Low" for maximum quality. Use "High" only when file size is critical.
No — everything runs locally. Very large files (100MB+) take longer to process.
