How do I compress a PDF to 100KB for government job forms?

Upload your PDF document to NexifyLabs PDF Compressor, click the '100 KB' quick preset button (or enter 100 in the target size box), and click 'Compress PDF'. The tool uses an adaptive rendering loop to guarantee the file is under 100KB while preserving sharp text.

Are my private documents and marksheets safe when compressing?

Yes, 100% safe. NexifyLabs processes documents entirely inside your web browser using WebAssembly and client-side JavaScript. Your PDF files are never uploaded to any remote server or stored in the cloud.

Why do recruitment portals like SSC and UPSC reject uploaded PDFs?

Most exam portals have strict file size limits (usually 100KB or 200KB max) and reject any document that exceeds this threshold by even 1 kilobyte. Using our exact target size preset ensures your PDF complies with portal requirements on the first attempt.
