How to Compress a PDF Online — Step by Step
Upload your PDF
Drag and drop your PDF onto the upload area, or click to browse and select it from your device. Files up to 200 MB are supported.
Choose compression level
Select Screen for the smallest file size, Web for a balance of size and quality, or Print to maintain high resolution while still reducing file size.
Compress
Click 'Compress PDF'. Each page is rendered and re-encoded in your browser — no upload required. A progress bar shows the current page.
Download
When complete, you'll see the original size vs. compressed size and the percentage saved. Click 'Download Compressed PDF' to save it.
Three Quality Modes
Screen (smallest), Web (balanced), or Print (high quality) — choose what fits your use case.
All Page Sizes
Works with A4, Letter, Landscape, and any custom PDF page size. Page dimensions are preserved exactly.
100% Private
PDF is compressed locally in your browser using Canvas rendering. Nothing is ever sent to a server.
Common Use Cases
Email Attachments
Many email providers limit attachments to 10–25 MB. Compress large PDF reports, presentations, or portfolios to stay within limits without sacrificing readability.
Website & App Uploads
Smaller PDFs load faster when embedded on websites, uploaded to course platforms, or shared through apps. Reduce load times with the Web compression mode.
Cloud Storage
Free up Google Drive, Dropbox, or OneDrive space by compressing large PDF archives. Screen mode delivers the smallest files for archived documents.
Scanned Documents
Scanned PDFs are often very large due to high-DPI image content. Compress them to manageable sizes while keeping them clearly readable.
