在线压缩PDF
在不影响清晰度的前提下缩小文件大小，满足邮件或上传限制。
使用流程
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 压缩 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.
您的文件将保持私密
压缩 PDF 在隔离的处理任务中运行。您上传的文件和生成的结果会在下载有效期结束后自动删除——我们不会保留任何副本,下载链接也是随机生成、仅限单次使用且会过期的。
常见问题
No — this tool works without creating an account. There is no sign-up option at all right now.
压缩 PDF accepts PDF files and produces a PDF result, up to 1 file per job.
The visible content and page layout stay the same — this tool changes how the file is stored or processed, not what it looks like.
Your file is processed in an isolated job and deleted automatically, along with the result, once your download window ends.
Not yet — it's still being finished on our end so it can ship as a fully working tool rather than a half-working one.
