Large PDF files can be difficult to share via email or upload to websites. FreePDFNest compresses your PDFs by rendering each page as an optimized image and rebuilding the document. This can dramatically reduce file size, especially for image-heavy documents.
Compression Levels Explained
Low compression renders at 200 DPI with high image quality — minimal visual difference, moderate size reduction. Medium compression renders at 150 DPI — good balance for most documents. High compression renders at 100 DPI — maximum size reduction, suitable for documents where smaller file size matters most.
Frequently Asked Questions
How much will my PDF shrink?
It depends on the content. Image-heavy PDFs (scans, photos, presentations) can shrink by 50-80%. Text-heavy PDFs with few images may see smaller reductions.
Will text remain selectable?
Compressed PDFs render pages as images, so text will not be selectable in the output. If you need selectable text, use low compression or consider other tools.
Is there a file size limit?
No limits. All processing happens in your browser, limited only by your device's memory.
Are my files safe?
Yes. Everything happens locally in your browser. Your files never leave your device.
