A browser extension. No upload, no account, no limits with Pro.
Get it for Edge (free) See Pro 中文
Because online PDF tools upload your contracts, invoices and resumes to someone else's server. We do the opposite: everything is processed inside your browser, and it keeps working with the network unplugged.
Install it, pull your network cable, and try — every feature still works.

39 CNY not a subscription
Buy this major version once, keep it forever. Future major upgrades are half price for existing users. No auto-renewal, no account.
Payment runs through a third-party store; you get a licence key right after paying and paste it into the extension. Re-paste it on a new computer.
1. Click the extension icon → Pro in the top right → paste your key → Activate.
2. The badge turns Pro and all limits disappear immediately.
The key is verified offline — no network call, no email upload. Lost it? We can reissue from your purchase record.
Does it work in Chrome? Yes, same package. Chrome Web Store review is pending; you can load it unpacked for now.
Does it upload my files secretly? No. The extension requests a single permission, storage, and declares no network hosts.
Encrypted PDFs? Not supported — decrypt first.
Can it compress scans? Yes: compression re-encodes the embedded images. Text-only PDFs barely shrink (they are already small).
Can I get an invoice? Yes, a Chinese invoice (个体户) is available on request.
Status (12 Nov 2026): the free version is live on Edge; the Pro payment channel is being set up, so Pro is not on sale yet. Existing installs are unaffected.
