How do I compress a PDF to 100 KB or 200 KB?

Upload your PDF, enter the target size such as 100 KB or 200 KB, and download the compressed file. The tool keeps reducing the size until it fits the limit.

Will text in my PDF stay readable after compression?

Yes. The compressor keeps text sharp and mainly reduces images. Grayscale and monochrome modes make scanned documents even smaller.

Why do government and exam portals limit PDF size?

Portals such as SSC, UPSC, scholarship and KYC sites accept only small uploads, often under 100 KB to 500 KB, so documents must be compressed before submitting.

Is my PDF uploaded when I compress it?

No. Compression runs in your browser and your PDF never leaves your device.
