Compress PDF
Make a large PDF smaller — ideal for scans you need to email or upload.
Runs in your browser — your files are never uploaded.
Pages are re-saved as images, so text in the compressed file can no longer be selected or searched. Best for scanned documents.

Questions
Why did my file not get smaller?
Text-based PDFs are often already compact. If compression would make the file bigger, the tool tells you and you can keep the original.
Are my files uploaded?
No. The tool runs inside your browser. Your PDF never leaves your device and is not sent to Accohub or anyone else — you can even disconnect from the internet after the page loads.
