Questions
Which level should I choose?
Medium suits most documents. High makes the smallest file by lowering image quality more; Low keeps images closest to the original.
Why didn’t my file get much smaller?
Most of a PDF’s size is usually its images. A PDF that is mostly text is often already small.
Is it free?
Yes. No account and no watermark. Files can add up to 25 MB per job, and you can run about 20 jobs an hour. A Docluster account (free for 14 days) gives you more room and keeps your documents organised.
What happens to my files?
Your files are processed on our servers and the result is kept for one hour so you can download it. After that the result is deleted for good. We don’t keep your original files, and we don’t ask who you are.
