Compress PDF under 100KB online

A 100KB PDF limit is strict. This page helps you prepare the file and explains when you may need to reduce pages, scan resolution, or source image size first.

Open the PDF compressor with a 100KB target

The current PDF compressor reduces file size and shows the output after processing. Exact KB compression depends on the source file, so check the downloaded size and try removing pages or resizing source images if needed.
