Compress PDF

Make Your PDFs Smaller

Large PDF files can be difficult to send by email or upload to websites that have size limits. Our compression tool reduces the file size of your PDFs so they are easier to share, store and transfer. The tool uses Ghostscript, an industry-standard PDF engine, to compress images within the PDF while keeping text and layout intact.

Three Compression Levels

Choose the level that fits your situation. The Low setting produces the best visual quality with a modest size reduction, ideal for documents that will be printed. Medium is the most popular choice, offering a solid balance between file size and appearance for everyday sharing. High compression creates the smallest possible file, which is perfect for email attachments, web uploads, or archiving where size matters more than image sharpness.

What Gets Compressed

The tool targets embedded images, which are usually the biggest contributors to PDF file size. Text, fonts, vector graphics and document structure remain unchanged. The result is a file that looks nearly identical to the original but takes up significantly less space on disk and transmits faster over the network.

When to Compress

Email services typically limit attachments to 10-25MB. Cloud storage services charge based on space used. Website upload forms often cap file sizes. Compressing your PDFs before sharing solves all of these problems. If you regularly work with scanned documents or image-heavy reports, compression can save you a significant amount of storage and transfer time.
