FAQ
Is it free? Any daily limit?

Yes — no paywall and no daily quota. Device memory is the practical limit for very large files.

Does my file get uploaded?

No. Processing is local. Only normal site scripts and WASM engines load from the CDN.

Password-protected PDFs?

Unlock them first. Encrypted PDFs cannot be processed while still locked.

Compress barely reduced my file?

Optimize is lossless and may change little on already-tight or image-heavy PDFs. Try Balanced or Strong for scans.
