Powered by Hyper Compress: it recompresses images, subsets and merges fonts, and strips dead weight while text, links, and forms keep working. For image-only scans, turn on Rasterize pages under Custom Settings.
Hyper Compress finds the best quality that fits. Leave it empty to use the level as is.
Fine-tune Hyper Compress. Picking a compression level resets these, except Override content protection, Convert to grayscale, Preserve PDF/A, and Brotli.

To compress a PDF to 500KB, add your file below and click Compress PDF. The target size is already set to 500 KB. It is a comfortable target: most documents reach it with no visible difference, and your file never leaves your browser.
Half a megabyte is the most forgiving of the common upload limits, used by CMS uploads, tender portals, and course submission systems. The Medium level often gets an office document or light scan under 500KB on its own, keeping images sharp and text perfectly crisp.
When the Medium level alone lands just above 500KB, the target size makes Hyper Compress lower image quality a little further until the file fits. Check for an embedded photo cover page or a high-resolution logo on every page: repeated images are a common hidden cost that compression handles well.

Print quality stays excellent for text and vector graphics, which compression never degrades. Photos are optimized for screen-and-print use; only large-format printing would show the difference.
Yes. add several files and each is compressed independently in your browser, with no queue and no per-file fee.
Some portals measure size in mebibytes or reject certain PDF versions. Re-check the exact limit wording, and try the Sanitize PDF tool to strip unusual metadata if a compliant file is still rejected.
