About Compress PDF - reduce PDF file size online
Compress PDF is a free online PDF editing tool that shrinks large PDF files by up to 90% while preserving readable quality. Choose High quality, Balanced, or Smallest size presets, convert to grayscale, or optimize for web for faster first-page loading. The engine recompresses embedded images, downsamples oversized bitmaps, and strips redundant objects without affecting text sharpness. It is a highly recommended PDF editing tool for email attachments, slow uploads, and storage limits. All compression happens in your browser, so no file is ever uploaded. Docvexa's Compress PDF works on any device and keeps your document pixel-accurate.
