ClickPDF
Optimize PDF size directly in your browser. Your file is never sent to a server.
Use Compress PDF when a document is too large to send, upload or archive comfortably. It helps with scanned contracts, invoices, reports, presentations and image-heavy files that can exceed email limits such as Gmail’s roughly 25 MB attachment cap. Image-based PDFs usually shrink the most, while text-only or already optimized documents may reduce only slightly.
Choose a compression level based on the job: stronger compression for scans you need to share quickly, recommended compression for everyday documents, and lighter compression when keeping visual quality matters more than maximum savings. The result is a smaller PDF that is easier to email, store in cloud folders, submit through forms or keep in a document archive.
The PDF is processed on your device. ClickPDF does not upload the document to a server for compression, so sensitive invoices, contracts, bank statements and internal reports stay inside your browser session. If the tab is refreshed or closed before downloading, the generated file may be lost.
It depends on the document. Scans and PDFs made from photos can often shrink significantly because images are recompressed. Text-based PDFs, exported invoices or files that were already optimized may only become a few percent smaller.
Recommended compression is designed to keep documents readable for normal sharing. Extreme compression produces smaller files but can reduce image sharpness, especially on scans with small print or stamps.
Yes. This tool is useful when a PDF is close to an attachment limit, including Gmail’s roughly 25 MB limit. If a file is still too large after compression, try a stronger preset or split the document into sections.
Some PDFs already contain optimized images or mostly text and vector graphics. In that case there may be little redundant data to remove without damaging quality.
