About Batch and Interactive Editor

How to use Interactive Editor

  1. Choose Interactive Editor to open originals, or use Edit in editor to carry your current settings across.
  2. Edit supported text and images, add content, fill forms, place signatures or arrange pages. Undo and Redo let you try changes.
  3. Use Export to save a PDF, or save a project to keep the document editable.

Each mode retains its own session until reload. Batch keeps its settings and results when you switch modes. Nothing is saved automatically.

Some PDF content cannot be separated into editable objects. Those pages keep their original appearance as a page background; you can add content over them.

How it works

How to fill in a PDF form

  1. Add the PDF form. Its first page appears with every field ready to type into; use the page strip, Previous, Next or the page number to move through it.
  2. Click a field on the page or use the Fields in this form list in the panel. Type, tick boxes and pick options there. Tab moves to the next field on the page, and Next empty field finds unanswered fields.
  3. Click Save filled PDF, check the preview, then download it. Switch on Lock answers first if you need a flat copy, or send the result to Sign PDF to add your signature.
Try a blank practice form

Download the synthetic practice form, then open it above. It has four fields: Name (required), Session, Notes and Send a reminder.

  1. Type Ayşe Yılmaz in Name, choose Afternoon, write Practice only. in Notes and tick the reminder.
  2. Leave Lock answers off, choose Save filled PDF, download and reopen the copy. Check that the answers are still editable.
  3. Save another copy with Lock answers on. The visible answers should remain, with the interactive fields removed. Flattening does not prevent PDF editing.
Which forms work, and what changes in the file

Any PDF made with fillable fields — text boxes, check boxes, radio buttons, drop-down lists and list boxes — the kind Adobe Acrobat, Word's "Export as PDF form", LibreOffice and most government and school sites produce. A PDF that only looks like a form (a scanned sheet, or lines printed on the page) has no fields; for those, Sign PDF places text and dates anywhere on the page.

What changes in the file

Only the fields you change are rewritten, in place: pages, other fields, links, bookmarks and document information stay as they are. Each changed field gets a new appearance so every PDF reader shows the answer the same way; check boxes and radio buttons keep the form's own tick style. With Lock answers on, every field is drawn into its page and removed, so they are no longer editable form fields. This does not prevent editing the PDF itself.

Refused and special forms

Forms with restrictions open straight away, and password-protected forms ask for their password; either way the form is decrypted in your browser and the filled copy is saved without encryption. Forms that already carry a digital signature are refused, because saving a filled copy would invalidate it. XFA-only forms — "Please wait…" forms that open only in Adobe Reader — cannot be filled outside Adobe's software. Some forms carry both an XFA version and a standard one; the standard one is filled and the XFA part removed so that every reader shows your answers.

Frequently asked questions

Useful details

8 answers
Is my form uploaded?

No. Opening, rendering and filling happen in your browser. The PDF and every answer you type stay on your device and are not written to storage either — they live in this tab until you reload or close it. Website hosting and performance measurement are described in our Privacy notice.

Will the filled form still be editable?

Yes, by default. Your answers go into the form's own fields, so you or the recipient can open the file in any PDF reader and change them. Switch on Lock answers before saving to draw the answers into the pages and remove the interactive fields. This does not prevent someone editing the PDF itself.

My PDF has no fields to fill. What now?

Then it is a flat form: a scan, or lines printed on the page, with nothing to type into. Open it in Sign PDF, which places text, dates and your signature anywhere on the page. The tool offers that button when it finds no fields.

Can I type in Turkish, Polish, Greek or Russian?

Yes. Answers the standard PDF font cannot spell are drawn with Liberation Sans, an open-licensed font embedded in the file, so letters such as ş, ğ, İ, ł, ř, Greek and Cyrillic appear exactly as typed. Chinese, Japanese, Korean, Arabic, Hebrew and other scripts are drawn inside the field with your device’s own fonts, joined and right-to-left where the script needs it, while the typed text is saved as the field’s answer.

Why didn't the total calculate itself?

Some forms contain small programs that add up totals, reformat dates or check what you typed. Those scripts are not run here, so type the final values yourself. The saved file still contains the scripts, and a reader such as Adobe Acrobat may run them when the recipient opens it.

Can I sign the form too?

Yes. Fill it here, save, then use Send to → Sign PDF to draw, type or upload your signature and place it on the signature line. Empty signature boxes in the form are shown here as a reminder.

Can I fill it on my phone?

Yes. The Fields in this form list lets you type and tick boxes at phone size. You can also tap fields on the page; the page strip and page number field jump to any page.

Which forms are refused?

Forms that already carry a digital signature — filling them would invalidate it — and XFA-only forms that open only in Adobe software. Protected forms ask for their password and restrictions-only forms open directly; the saved copy has no encryption. This is not a redaction or metadata-removal tool.
