Aurora PDF Compressor — Compress PDFs locally in your browser. No uploads. No limits. No account.

Hi Product Hunt! 👋

We built compress.aurorapdf.com because we kept running into the same problem.

Every time we needed to shrink a scanned contract or a heavy report to squeeze it under a 25MB email limit, the only options meant uploading the file to a third-party cloud server. For sensitive work documents, that never felt right to us.

So we built something different.

Here is how it works:

- 🔒 100% local processing — Your file never leaves your device. Everything runs inside your browser tab using your machine's memory. No server. No storage. Nothing.

- 🎚️ Three compression levels — Extreme, medium, and light. The light preset is specifically tuned to keep scanned text sharp instead of turning it into a blurry mess.

- ✅ No account. No watermark. No daily cap. Open the page, drop your file, get a smaller one back.

Where we are still improving:

Very large files on low-RAM machines will slow your browser down. Client-side processing has limits and it is something we are actively working on.

If you handle sensitive documents and want to keep them off third-party servers, we think you will find this genuinely useful.

We would love to hear how it holds up with your files. Drop any questions or feedback below 👇
