This information helps when reporting an error
The most helpful information is the exact step at which something happens differently than expected. For example: “When splitting a five-page PDF, I entered 1-3. After I click start, the following error message appears …”
- Name or page path of the tool you used.
- Device, operating system and browser with version number.
- The steps you took and the settings you chose; for calculators, also the values and units you entered.
- The expected result, the actual behavior and the exact wording of any error message.
- For a file problem: file type, approximate size and page count. If applicable, mention password protection, digital signatures or form fields.
A description is enough to start with
Please do not include a PDF, Word file or confidential document content in your first message. The steps, settings and error message are often enough to help. If an example is needed later, a file created specifically for this purpose with made-up details is more suitable than a certificate, contract or tax receipt.
Also check screenshots for personal data, login credentials and confidential file names. The contact form does not support file attachments.
Find the right help directly
File limits and supported features lists the rules for the tools. How it works explains selecting, editing and saving. If a successfully processed PDF barely gets smaller, the guide PDF won't get smaller can help.
If you have a suggestion for improvement, it's best to describe your task and the step that could be simplified. That makes it clear how a change would help.
Messages and responses
The email link opens your own email program, where you decide whether to send the message. The form can only be used once a sending service has been set up. You can see its current status directly above the input fields.
A sending confirmation from the form means that the configured email service has accepted the message. It does not confirm a reply, nor does it yet confirm receipt in the receiving mailbox. There is currently no fixed response time.
Contact messages and your email address are transmitted via an email service. This is a separate process from the local processing of PDF files in the browser. Information about the data transmitted can be found under Privacy.
