Frequently asked questions
Can I compress a PDF to 100 KB here?
No, this tool handles images. Use Compress PDF for PDF files.
Is 100 KB the same as 0.1 MB?
Close: 100 KB is 102,400 bytes, about 0.098 MB. Forms that say 100 KB almost always accept files reported as 100 KB or less.
Why does the form say my file is still too big?
Some sites count 1 KB as 1,000 bytes instead of 1,024. If that happens, set a target a few KB lower.
