Compress PDF Online | Reduce PDF File Size | FlamePDF
Compress PDF files for email, job applications, and upload portals. Choose a quality level, process multiple PDFs, compare results, and download smaller files in your browser.
Reduce a PDF file size
Add a PDF, choose the available compression settings, and compare the resulting file size with the original. Review text, images, and page appearance before sharing the compressed copy.
When compression helps
A smaller PDF can be easier to email or upload when a portal enforces a file-size limit. Keep the original if you need to compare quality or repeat the export with different settings.
