Compress PDF

Reduce some PDF file sizes by rasterizing and recompressing pages with selectable compression presets.

Processing happens in your browser. Large PDFs may require significant memory and can take longer to process.

Compression rasterizes each page before rebuilding the PDF. This can reduce image-heavy or scanned PDFs, but it also flattens selectable text, links, forms, and other interactive PDF content. Some already-optimized PDFs can become larger instead of smaller.

About this tool

What is Compress PDF?

Create a smaller rasterized version of a PDF using browser-based page rendering and JPEG recompression. Choose maximum, balanced, or higher-quality compression. This approach can work especially well for scanned or image-heavy PDFs, but it flattens selectable text, links, form fields, and other interactive content.

Frequently asked questions

Questions about Compress PDF

How does this PDF compressor work?

It renders each page as an image, recompresses the rendered page, and rebuilds the PDF from those page images.

Will text remain selectable after compression?

No. Because the pages are rasterized, selectable text, links, forms, and other interactive PDF content are flattened.

Will every PDF become smaller?

No. Image-heavy or scanned PDFs can often shrink, but PDFs that are already optimized may stay similar in size or even become larger.
