Questions
Why did my PDF barely shrink?
Text-only PDFs are already compact. The biggest savings come from PDFs with photos or scans. Try the Strong level for scanned documents.
Are my files uploaded to a server?
No. The tool runs in your browser using your own device. Your file is never sent to us or anyone else — you can even disconnect from the internet after the page loads.
Is it really free?
Yes. There is no account, no watermark and no daily limit.
Is there a file size limit?
There is no fixed limit. Very large files depend on your device memory — a modern phone or laptop handles files of several hundred MB.
