Compress PDF reduces the file size of a PDF by re-encoding the images inside it, subsetting embedded fonts to only the glyphs the document uses, and rebuilding the document's internal structure, all without uploading your file anywhere. Image-heavy PDFs are large because of their scans, and text-heavy PDFs are often large because of fully embedded fonts; the tool targets both while leaving text and vector graphics sharp, selectable, and in their original colors.

Choosing a level is simple. Low does light optimisation for when quality matters more than size. Medium is the everyday choice, a strong size reduction you generally can't see. High and Extreme squeeze the file smaller for strict upload limits, accepting slightly softer images in return. Or skip the levels entirely and use Target file size: type the exact size you need and the tool finds the best quality that fits. For text-only PDFs that can't reach a very small target without rasterizing the text, it gets as close as possible and tells you the closest size, it never blurs your text to hit a number. After processing you'll see the original size, the new size, and the exact percentage saved.

Because everything runs locally in your browser, your document never touches a server. That makes Compress PDF safe for confidential material, contracts, financial statements, IDs, and medical records, that you would not want to upload to an online service.
