Compress PDF — Free Online, No Upload Shrink image or PDF file sizes down to a target for free, right in your browser. Perfect for speeding up websites, meeting upload limits, or emailing files — all without uploading anything to a server.
How to use Compress PDF Drop your image (JPG, PNG, WebP) or PDF into the box above. Pick a target output size. Download the smaller, optimized file. Frequently asked questions How can I reduce image file size without losing quality? Pick a target size close to the original — the tool only lowers quality as much as needed to reach it. Compression happens locally in your browser.
Can I compress a PDF file? Yes. Drop in a PDF and pick a target size — each page is recompressed to fit, and a smaller PDF is rebuilt for you to download. Note that any selectable text becomes part of a page image in the process.
Is this compressor free? Yes, it is completely free with no watermarks and no sign-up required.
