How PopDF works, what its messages mean, and how to reach us. Most answers are a few lines.
Need a person? Email technical@liqtek.com. Tell us what you were doing, what you expected and the exact message you saw. Never send us a PopDF link: links hold the key to your document, and we don't need them to help. We answer within one working day (Malta time).
Getting started
- Send a contract for signature. In the app, choose Send a contract, upload a PDF (up to 8 MB), add the signers, drag the fields (signature, name, date and so on) onto the pages, and send. You get a private link for each signer, to share by email, WhatsApp, Teams or QR code, and an owner link for you.
- Agree the wording first. Choose Edit and agree a document and upload a Word document (.docx). Everyone edits it in the document editor, saving versions, until each person presses Agree. Then it becomes a PDF with signature blocks and goes for signing.
- Sign. Open the link you were sent, add your details, agree to sign electronically and fill in your fields. On a phone, PopDF takes you through them one at a time.
Guests and accounts
- Signers need nothing: they sign as guests, with their details kept in their browser.
- Senders confirm their email with a 6-digit code we email them. There's no account to create and no password. The free plan includes 1 contract a month, counted by that email address.
- Optional: keep everything you send, sign or agree in one list on every device, opened with a passkey or a recovery code.
- Your passkey or recovery code unlocks that list. It is encrypted, and we can't open it. Keep the recovery code safe: if you lose both, we can't recover your list. You can make a new recovery code, add passkeys and turn on two-step sign-in from your account page.
- Close your account from its page. You can also pop everything you sent at the same time.
Links
- Each person gets their own link. The part after the # holds the key to the document, and browsers never send it to any server. That's why we can't read your documents, and also why we can't recover a lost link.
- The owner link opens the sender's controls: status, re-sharing links, reminders, popping. Copy it, email it to yourself or save it as a file when you send. If you've set up your list, it's in there too.
- A signer lost their link? Open your owner link and press Share link beside their name, or Send a reminder.
Popping
- The countdown at the top of every document says how long until it pops. Unsigned links stop working after 7 to 90 days, as the sender chose. Once everyone has signed, the envelope pops 1 to 365 days later.
- Download your sealed copy before it pops. After that, nothing is left on our servers, not even the encrypted file.
- The sender can pop an envelope at any time from the owner link.
Files
- PDFs up to 8 MB and 200 pages. Password-protected or restricted PDFs can't be used: open them and save or print a new copy without the password. Scripts, actions that run on opening and attached files are removed before anything is encrypted. Fillable forms are shown as they are, so fill them in first.
- Word documents (.docx) for editing. PopDF takes the text: headings, paragraphs, lists and tables. Pictures, comments, headers and footers are left out, and PopDF tells you what was left out. Older .doc files: save them as .docx first.
- Languages: PDFs PopDF makes cover every European language, including Maltese, Greek and Cyrillic. Chinese, Japanese, Korean, Arabic and Hebrew letters can't go into those PDFs yet. PDFs you upload can be in any language.
- Logo and watermark: when sending, you can add your logo and a watermark to the final sealed copy.
The checks PopDF shows you
- "Checked: this PDF is exactly the wording you agreed to" means the PDF you're signing was rebuilt from the agreed text and matches it exactly.
- "Do not sign yet" means something doesn't match. Don't sign it; ask the sender.
- "Your copy matches" on a sealed PDF means it is byte-for-byte the same as everyone else's.
Common messages
- "This link is incomplete": part of the link is missing. Copy the whole link again, including everything after the #.
- "This envelope has popped": it was deleted, on schedule or by the sender. If you need it again, the sender has to send it again.
- "Someone saved a newer version while you were editing": your changes are still in the editor. Look at theirs with Show changes, then save yours again.
- "First, confirm your email": the sender asked signers to prove their address. You'll get a 6-digit code by email; there's no account to create.
- "Too many … today": a safety limit. Try again tomorrow, or sign in.
