How to compress a PDF to 100KB
- Add a PDF file.
- Click Compress to ~100KB.
- Download the result. The filename shows the achieved size (e.g.
omnipdf-96KB.pdf).
If 100KB cannot be reached without destroying readability, the tool returns the smallest file it found and reports the actual size.
Privacy
Everything runs in your browser. Nothing is uploaded.
Known limitations
- An exact byte target is not guaranteed.
- Text becomes rasterized; you cannot select or search it in the compressed copy.
- Very long or image-heavy PDFs may exceed 100KB even at the lowest setting.
Frequently asked questions
Why is my result 120KB instead of 100KB?
Because 100KB was not achievable without severe quality loss, or the PDF is too complex. The tool returns the smallest file it could produce and shows its size in the filename.
What if my PDF is already below 100KB?
The tool returns your original file unchanged and notes that no compression was needed.
