Compress PDF to 500KB

500 KB is a very common ceiling for document uploads, and luckily it's also a size where most documents still look good. This page starts the compressor with a 500 KB target already set. Drop your PDF, click Compress PDF, and the tool automatically increases the compression until the file is at or below half a megabyte. You don't have to guess between low, medium and high; the target size handles it for you.

At 500 KB, a scanned document of around ten pages usually stays clear, and photos inside a report remain recognizable rather than blocky. That makes this target a good choice for rental applications, school enrollment packs, supporting documents for claims, and portfolios with a handful of images. If your source is a huge scan from a multifunction printer — those can easily reach 30 MB — you'll see the most dramatic reduction.

Remember how the compressor works: each page is redrawn as an optimized JPEG image. That keeps the look of the page but removes selectable text and clickable links, so this is best for scans and image-heavy files. If your PDF is mostly digital text and is only slightly over 500 KB, it can be worth checking whether it contains unnecessary pages instead. All processing is local, so the file never leaves your computer or phone, and you can compress as many documents as you need.

If you're preparing several attachments for the same application, compress each one separately to 500 KB rather than merging everything first; that way each file stays well within the limit and the reviewer can open them individually.
