Compress PDF to 1 MB

1. Drop one or more PDFs onto the page, or click to choose them.
2. Fit to size is already selected with a 1 MB 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 1 MB 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.

Usually only slightly. Fit to size tries the lightest setting that fits first, and many documents reach 1 MB without visible changes.

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 1,000,000 bytes, the stricter reading of 1 MB, so the result passes upload forms that use either definition.

Each file can be up to 100 MB, and the files you add at once can total up to 200 MB. Large, image-heavy files take longer because they are processed on your own device.
