Terms of use
Last updated on 4 November 2026. By using TweakPDF you agree to these terms.
The service
TweakPDF (tweakpdf.app) fixes and replaces text in existing PDF files and lets you add your own signature to them. It is run from Poland. You can reach us at support@tweakpdf.app.
Your files
Your files stay yours. We use them only to show and change them for you, and for nothing else. A file is deleted from the server two hours after you stop working; a downloaded result stays 24 hours so you can download it again.
Fair use
Change only documents you have the right to change, and sign only with your own signature. Do not use TweakPDF to forge or falsify documents, such as bank statements, pay slips, certificates, diplomas, IDs or signed contracts, or to deceive anyone. Do not try to break, overload or scrape the service. We may close an account that breaks these rules.
Free and Pro
The free plan gives 3 downloaded files a month per Google account; the count resets on the 1st of each month (UTC). Pro gives up to 1000 files a month for $6 a month, $24 for six months or $36 a year. Pro renews at the end of each period until you cancel. You can cancel any time from the account menu, and Pro stays on until the paid period ends.
Payments
Stripe sells Pro as the merchant of record: it takes the payment, sends the receipt and handles sales tax and VAT. Prices are in US dollars and include tax. Stripe's terms also apply to the payment.
Refunds
If Pro did not work for you, write to support@tweakpdf.app within 14 days of a payment, from the address you signed in with, and we will refund that payment in full, no questions asked. This does not limit your rights as a consumer.
Check before you send
We work to keep every result clean, but rare fonts, damaged files and complex pages do not always come out perfectly. The preview shows the finished file before a download counts against your limit; check it before you use or send the file. TweakPDF is provided as it is. As far as the law allows, we are not liable for indirect losses, and our total liability is limited to what you paid us in the last 12 months.
Changes
We may change the service or these terms; the date at the top shows the current version. If a change makes Pro worse for you, we will tell you by email before it applies, and you can cancel. You can stop using TweakPDF at any time.
Law
These terms are governed by Polish law. If you use TweakPDF as a consumer, you also keep the protection of the mandatory law of the country where you live and can go to its courts.
