About Compress PDF
Large PDF files can be difficult to upload, email, store, or share. Our compress PDF tool helps reduce the size of supported PDF documents while aiming to maintain useful document quality. You can compress PDF document files directly from your browser without installing desktop software. If your PDF is too large, you can reduce PDF size, decrease PDF size, or minimize PDF size when storage or upload limits are a concern.

You get back: A smaller PDF, with the reduction actually achieved shown next to the original size.
Good to know before you start
- You can aim for a 50% to 90% reduction, but a short text-only PDF has less to remove and may fall short of the target.
- Pages produced by this tool are drawn as images, so the text inside them is no longer selectable or searchable.
- Fine print and thin line art soften at the strongest targets, so choose 50–60% for anything you will print.
Why use this tool
Compress PDF file online
Our document compressor provides a simple way to compress PDF file online. How much compression is possible varies: image-heavy PDFs may behave differently from text-based documents.
Reduce PDF size without losing quality
Compression always involves a trade-off between file size and quality, so the best result depends on the original document. The aim is to compress PDF without losing quality as much as reasonably possible while keeping the document readable.
Compress PDF to 200KB
If you need to compress PDF to 200KB, the final size depends on the original file, page count, images, fonts, and other content. A very large or image-heavy PDF may not reach 200KB without noticeable quality reduction.
