About PDF Compressor
Large PDFs are a pain: email systems reject them, upload forms time out, and cloud storage fills up. PDF Compressor shrinks file size directly in your browser by re-encoding images and streamlining internal structures, while keeping text selectable and sharp. Because the work happens on your device, even confidential documents stay private.
The tool gives you a practical trade-off slider — push for the smallest possible file when emailing, or choose a lighter touch when print quality matters. You see the resulting size before you download, so there is no guesswork.

Frequently Asked Questions
How much smaller will my PDF get?
It depends on the content. Scanned documents with large images often shrink by 60–90%, while text-only PDFs are already efficient and compress less. The tool shows the final size instantly.
Will the text stay selectable after compression?
Yes. Compression re-encodes images and cleans up structure — the text layer remains searchable and copy-paste friendly.
Is there a file size limit?
No server means no artificial cap. Your browser and device memory set the practical limit, which comfortably covers most real-world documents.
Are my files private?
Completely. The PDF is processed locally in your browser and never uploaded to any server.
