Reduce the file size of your PDF documents while keeping their layout and quality. All processing is done inside your browser, keeping your documents secure.
Choose a PDF document to shrink its file size.
Large PDF files are difficult to share via email, upload to web portals, or store in cloud databases. Our Compress PDF tool provides an easy, browser-based solution to optimize your PDF files. By downsizing images, compressing font streams, removing redundant metadata, and cleaning up cross-reference tables, the tool slashes file size while maintaining excellent visual readability.
Unlike other services that require you to upload private files to their servers, our compression engine runs 100% locally. Using optimized WebAssembly code, it compresses embedded image streams (such as converting heavy PNGs to optimized JPEGs) and strips structural bloat right in your browser, keeping your documents completely private.
Step 1: Drag and drop your heavy PDF file into the file upload box or browse from your device.
Step 2: Select your target compression level: High Compression (lower quality), Medium Compression (recommended balance), or Low Compression (maximum quality).
Step 3: Review the estimated output size and quality settings.
Step 4: Click "Compress PDF Document Now" to start local optimization.
Step 5: Once processing is complete, download the compressed PDF file instantly.
