11zon's "Compress PDF to 200KB" page produced 209.92 KB from our 2.04 MB scan in both of our tests, over its own title and with no warning, and 11zon's privacy policy says files are stored on its servers for processing. CompressKaro produced 180.5 KB without uploading. Both offer a Hindi interface.

Where 11zon is better

  • Hindi interface (CompressKaro has it too) and a very wide range of tools.
  • Batch processing with a single ZIP download.
  • Well known in India.

Where CompressKaro is better

  • Actually under 200 KB on the 200 KB task (180.5 KB vs 209.92 KB).
  • You set the size in KB, not a percentage.
  • No upload: the file stays on your device.

Which should you use?

If you use 11zon, check the "New size" before uploading to a portal. For limits that must be met, use a tool that targets the KB size you type.

How we tested

On 17 October 2026 we ran each tool in Chrome with the same synthetic 2.04 MB scanned PDF, measured the file each one produced for a 200 KB limit, and logged every network request that could carry the file. Numbers can differ with other files. Full method and its limits: how we test. Results for all tools: compare PDF compressors.
