About PDF Compressor

PDF compressor reducing a PDF file to a target size in KB

The PDF Compressor reduces the size of a PDF to the limit your form requires, such as 100 KB or 200 KB. You enter a target size, the tool tries a lossless optimisation first and, if that is not enough, compresses the pages step by step until the file fits.

When strong compression is needed, pages are converted into compressed images, so text can no longer be selected. For most scanned documents this makes no visible difference. The whole process happens in your browser and your file is never uploaded.

Tips

Enter a target size to let the tool keep compressing until the file fits.

If a lossless optimisation is enough, your text stays selectable.

Compressing to a very small size turns pages into images, so text is no longer selectable.

Very large PDFs (over 150 pages) should be split first.
