Make image-heavy PDF files smaller and easier to share. Everything stays private in your browser.
About this tool
Compress PDF Online
This PDF compressor is designed for scanned documents, photo portfolios, and other image-heavy PDFs. It rebuilds pages with compressed page images, which can make large visual documents easier to email or upload.
The conversion happens on your device. Because pages are flattened during compression, selectable text, forms, links, and advanced PDF features may not remain interactive.

Common questions
PDF Compressor FAQ
Does the PDF leave my device?
No. The selected file is processed in your browser and is not uploaded to Plain North.
Why did my PDF become larger?
This method is optimized for image-heavy documents. Very small, text-based, or already optimized PDFs can grow when each page is rendered as a new image.
Will links and selectable text still work?
The compressed document is flattened into page images, so links, form fields, annotations, and selectable text may no longer work. Keep the original file as your editable master.
