Smart Compression, Not Just Shrinking

We compress what matters and leave everything else exactly as it was.

Up to 90% Smaller

Our compression engine removes redundant data, downsamples embedded images, and strips hidden metadata — shrinking most PDFs by 50–90%.

Three Quality Levels

Choose between Maximum compression for email attachments, Balanced for everyday sharing, or High quality for print-ready output.

Text Stays Sharp

Text, fonts, and vector graphics are never degraded — only embedded raster images are compressed. Reading quality is always preserved.

Fast Processing

Most PDFs are compressed in under 10 seconds regardless of page count. Large scanned documents are processed on priority servers for Pro users.

Metadata Stripped

Hidden author info, edit history, and embedded thumbnails are removed — reducing file size and protecting your privacy at the same time.

Never Stored

Files are processed entirely in your browser session and deleted immediately. Nothing is stored on our servers after you download.

Frequently Asked Questions

Everything you need to know about this tool

Compression results depend on what's inside your PDF. Scanned image PDFs with large embedded photos often shrink by 70–90%. Text-heavy PDFs with few images may only reduce by 20–40%, since the text and fonts are already compact.

Yes — text and vector graphics are never re-encoded or degraded. Only embedded raster images are compressed. At 'High quality' mode, even image quality loss is imperceptible.

Maximum compresses images aggressively (72 DPI equivalent) — best for email where file size matters most. Balanced (150 DPI) is good for everyday sharing. High quality (220 DPI) retains near-original image quality with modest size reduction.

Yes — enter the password when prompted and the tool will compress it normally. The output file retains the same password protection.

Free users can compress files up to 10 MB. Pro users can compress files up to 500 MB — useful for large scanned document archives.
