Shrink PDF file size while keeping it crisp. Pick a compression level, preview the savings, and download, all processed privately in your browser.
FernPDF’s compressor analyzes your PDF and optimizes images, fonts, and structure to cut file size while preserving sharpness. Pick a level, preview the savings, and download.
Because everything runs locally in your browser, you can compress sensitive documents (tax records, medical scans, signed contracts) without ever sending them to a third-party server.
Smaller PDFs are easier to email, faster to load, and cheaper to store. “Recommended” is visually lossless for most files; “Strong” goes further when size matters most.
