Questions
How do I compress a PDF to 100 KB?
Add your PDF, keep 100 KB selected as the target and press Compress. The tool lowers the picture quality of each page until the file fits under 100 KB.
Will the text in my PDF still be selectable?
No. To reach a small size, each page is turned into a compressed picture. This looks the same on screen but the text can no longer be selected or searched.
What if my PDF cannot get down to 100 KB?
Very long PDFs or very small targets can make pages blurry. We use the best quality that fits and tell you if the result is not readable enough. Try a bigger target, black and white, or split the PDF first.
Is my document uploaded?
No. All of the work is done by your browser on your own device.
