The portal wants 5 MB. Your PDF is 18 MB.
Reduce PDF file size for email, upload portals, storage, and handoff without sending the document to an upload-first service.

The document is ready, then the upload limit starts acting royal.
Compress the PDF in the browser and download a smaller output file when a safe reduction is possible.
No upload-first habit
For standard PDF tools, file content is processed locally in your browser instead of starting with a cloud upload.
Simple flow
Choose the job, adjust the settings, and download a new output file. The original stays where it was.
Real PDF work
The toolbox covers everyday fixes and heavier document cleanup without turning every PDF into an installation project.
