FAQ
How do I compress a PDF to 300KB?
Add your PDF, keep the limit on "Under 300KB" and press Build. Pages are re-encoded just enough to land below the limit.
Are my documents uploaded?
No. Everything runs in your browser. Your files are never sent to a server.
Will the text still be selectable?
If the result is already under the limit, pages are copied as they are and text stays selectable. If compression is needed, pages become images, so text is no longer selectable.
How is the limit counted?
In decimal KB (1KB = 1000 bytes) with a small safety margin, so the file passes whichever way the portal counts.
