Compress PDF to 300KB

1. Upload your PDF (up to 50 MB).
2. The compressor automatically targets 300 KB or under.

300 KB is a comfortable target — most PDFs fit easily with minimal compression. Perfect for exam portals, forms, and email attachments.

300 KB is the target for portals and forms that need small PDFs but also want readable quality. Most documents fit easily with minimal compression, preserving sharp text and readable images.

The compressor analyzes the PDF, downsamples embedded images to appropriate resolution, and iterates until the output is 300 KB or under. Text is preserved losslessly.
