How It Works: Filling PDFs Made Easy
PDF Otter makes filling out PDFs a breeze. Simply upload your PDF, select where you want to add text, and start filling out the fields. You can customize the style of your text to match your needs.
Once you're done, download or print your filled-in document. Your documents are deleted after 24 hours for privacy. You can optionally sign up to save your files for future use.
Frequently Asked Questions About PDF Otter
How is PDF Otter free? We built this editor to showcase the PDF Otter API. Our API clients help keep this tool available for free.
Can I add a signature to the PDF? Yes, you can use a script font like Dancing Script to create a signature. While this is usually acceptable, it is not a legally binding e-signature. For true digital signatures, it is best to use a proper e-signature service.
How do I fill in checkboxes or radio buttons? Simply type 'X' in the checkbox or radio button to indicate your selection.
What kind of PDFs does PDF Otter support? We support PDFs under 10MB with consistent page sizes. Contact us if your PDF isn’t supported.
Can I save my template to reuse it? Yes, by signing up. Your templates and files will be saved, and we won’t delete them after 24 hours. You can delete them manually when you choose.
When can I add an image to my PDF? Currently, this feature is not supported, but it is on our roadmap. Contact us to request this feature.
