How to use Compress PDF
Add one or more PDFs.
Choose a compression level. "Recommended" suits most files.
Press "Compress PDF" and download the smaller file.
Questions
Which compression level should I pick?
"Light" keeps everything exactly as it is and removes waste, so savings are small. "Recommended" and "Strong" save pages as images for much smaller files, but text can no longer be selected.
I need my PDF under a specific size, like 100KB.
Use Compress PDF to 100KB, 200KB, 500KB or 1MB. Those tools keep trying until your file fits.
Why did my file not get smaller?
Some PDFs are already well optimised. If compressing would make the file bigger, Dekiko gives you back the original and tells you.
Are my files uploaded to a server?
No. Dekiko processes your files inside your own browser. They are never uploaded, so nobody else can see them, and they are gone when you close the tab.
