What Fill PDF forms does

Use Fill PDF forms to choose a PDF form, enter field values and save either editable or flattened answers. The form fields and their values stay inside the tab, and flattening is offered when recipients should not edit them. Filozy starts the document engine only after you choose a file, performs the work inside this tab, and creates a new result for you to save. Your selected document, its filename, and its contents are not sent to Filozy.

How to fill pdf forms in your browser

  1. Choose a PDF formSelect a PDF form from the dropzone. Filozy reads it locally and shows the relevant preview or controls before changing anything.
  2. Review the settingsUse the page preview and available options to decide exactly how fill pdf forms should handle this document.
  3. Create and check the resultRun the tool, review the reported page count, size, or notes, then save the newly created file while keeping the original.

Limits worth knowing

  • The result depends on the structure and quality of the source document, so visually inspect the exported file before relying on it.

Essential questions

Does Fill PDF forms upload my file?

No. The selected file is opened and processed by code running in this browser tab. Document bytes and filenames are not sent to Filozy.

Will this change my original file?

No. Browsers cannot silently overwrite the file you selected. Filozy creates a separate result for you to save or pass to another local tool.
