Compress PDF to 200 KB brings a PDF under 200 KB, a common limit for online applications, marksheets and supporting documents. It tries lighter compression first so the document stays readable, and it runs in your browser without uploading anything.
This tool runs entirely in your browser. Your files are processed on your own device and are never uploaded to a server. Your original file is never changed, and leaving or reloading the page clears it from the tool.
For a few pages of text or scans, yes. Fit to size keeps the sharpest version that fits, so it only uses the strongest compression when it has to.
The tool tells you and still gives you the smallest version it could make. To go further, remove pages you don't need with Delete PDF Pages, split the document with Split PDF and upload the parts, or rescan paper documents at a lower resolution or in black and white.
BoringPDF aims below 200,000 bytes, the stricter reading of 200 KB, so the result passes upload forms that use either definition.
No. The file is processed by your browser on your own device and is never uploaded. Closing or reloading the page clears it from the tool.
