Returning a filled PDF form without flattening it means sending a document the recipient can edit before filing it. For a signed quote or an administrative request, that is a weakness.
How it works
Drop your file on the page, or click to pick it from your folders.
Start the job. It runs inside your browser: nothing is sent to a server.
Download the result. No account, no watermark, no queue.
When this really helps
Return a form
Your answers can no longer be altered afterwards.
Archive a file
The document freezes in the state it was approved in.
Make printing reliable
Some readers do not print form fields; flattened, the problem disappears.
What the conversion keeps, and what it loses
Working inside a browser comes with limits a hosted service does not have. Here they are in plain words, so you know what to expect before you start.
What is kept
- The values you entered, in place
- Layout and fonts
- The document text, selectable
- Images and drawn signatures
What is not carried over
- The editability of the fields — that is the point
- Dropdowns and checkboxes, now drawings
- The form’s automatic calculations
- Certificate-based electronic signatures, which become invalid
Worth knowing about the format
Flattening relies on pdf-lib: field appearances are drawn into the page content, then the form is removed. If an appearance cannot be regenerated, the form is simply deleted — what is already displayed stays visible.
Not the right tool?
- Sign a PDF — Pour apposer une signature avant de figer le tout.
- Clean the metadata — Pour nettoyer ce que le fichier révèle avant de l'envoyer.
- Sanitize a PDF — Pour retirer en plus le JavaScript et les pièces embarquées.
Why it's free
Online converters receive your file on their servers, process it, then promise to delete it. Every document costs them computing time: that is why they charge, and why they cap file sizes.
Here, the work happens on your own computer. The page contains no server code: your document cannot be received, because it is never sent. So there is nothing to bill, nothing to cap, and nothing to delete afterwards. Cut your connection once the page has loaded — everything keeps working.
Frequently asked questions
Do my answers stay readable?
Yes, and in exactly the same place. They simply stop being editable fields and become page content.
Can I undo it?
Not on the produced file. Keep your original — a general rule with these tools.
What if my PDF has no form?
The tool says so and simply re-saves the document, changing nothing.

Edit the text in a PDF — Fix a line that is already written, even on a scanned document. This is the feature other services charge for, and the natural starting point when you need to retouch before converting.
