PDF扁平化
鎖定表單欄位與註解，讓 PDF 無法再被編輯。
運作方式
1. Upload your file
Drag and drop or choose a PDF file from your device. Everything is checked against its real file type before processing starts.
2. We process it
Your file runs through an isolated job dedicated to 展平 PDF, with clear progress so you always know what stage it's at.
3. Download the result
Get your finished PDF file with one click. The original upload and the result are deleted automatically afterward.
您的檔案將保持私密
展平 PDF 會在獨立的處理程序中執行。您上傳的檔案與產生的結果會在下載時限結束後自動刪除——我們不會保留任何副本,下載連結也是隨機產生、僅限單次使用且會過期。
常見問題
No — this tool works without creating an account. There is no sign-up option at all right now.
展平 PDF accepts PDF files and produces a PDF result, up to 1 file per job.
Only the specific change you make is applied — everything else on the page stays exactly as it was in your original file.
Your file is processed in an isolated job and deleted automatically, along with the result, once your download window ends.
