Frequently asked questions
Does my PDF get uploaded?
No. The PDF is processed entirely in your browser and never leaves your device.
Will text stay selectable after compression?
Document preservation mode keeps text selectable, along with links and page layout. Picture mode renders pages as images and is only used when you choose it.
What happens to digital signatures?
If the PDF is signed, compression rewrites the file: signatures remain visible but stop verifying. We explain this before processing and you decide whether to continue.
Why is the result slightly below the target?
Output is kept just under your limit with a small safety margin, so the file fits the field you are filling.
