What Is Compress PDF ?
Large PDFs are a pain: they fail email limits, slow down uploads, and waste storage. Compressing a PDF reduces its file size while keeping it readable, making it much easier to share and store.
Our Compress PDF tool re-encodes every page as an optimized image and rebuilds the document. This is extremely effective for scanned documents and image-heavy PDFs, often cutting file size by 50–80%. You control the balance between quality and size with a quality slider and resolution selector.
Everything runs locally in your browser, so confidential documents like contracts, invoices, and personal records are never uploaded. There is no watermark, no registration, and no usage limit.
Note: because pages are converted to images, text is no longer selectable after compression. This trade-off is what makes the file much smaller.
