Compress PDF
Drop a PDF, choose a quality level, and download the compressed file.
Large PDFs slow down email attachments, fail upload limits, and take forever to load on mobile. Our compressor re-encodes each page as an optimized JPEG image inside a new PDF, dramatically reducing file size while keeping text and images readable.
Use the quality slider to balance compression and fidelity. A setting of 70–80% delivers a great balance for most documents. Lower for scanned pages or diagrams where you need the smallest possible file.
The entire process runs in your browser — your document never leaves your device. No signup, no watermark, no file size cap beyond your device's memory.
