Compress PDF to 50 KB

1. Drop one or more PDFs onto the page, or click to choose them.
2. Fit to size is already selected with a 50 KB target. Pick a different size if your form needs one.
3. Click Compress and download the PDF. The result screen confirms whether each file fits.

• Aims for 50 KB and keeps the sharpest version that still fits.
• Tries lighter compression first, so text and images aren't degraded more than needed.
• Shows the total size before and after and each new file's size, and flags any file that can't reach the target.
• Compress several PDFs at once, and nothing is uploaded.

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.

Short text documents and single scanned pages usually can. A scan saved in color at high resolution, or a document with many pages or photos, often can't, even at the strongest setting.

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 50,000 bytes, the stricter reading of 50 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.
