To edit all PDF pages at once, load the file onto a canvas, split it into pages, and run one written instruction across the whole set. That is how you edit a PDF with AI instead of by hand. No page-by-page clicking, no rebuilding the document from scratch, no learning a new interface. You describe the change in plain language and every page comes back changed the same way.

That is what the Bulk edit all pages of a PDF template does in Picsart Flow. It takes a multi-page document, fans the pages out into a batch, and applies a single prompt to the whole stack. The template ships with a real instruction already sitting in the prompt bar: change the font to Times New Roman, remove all emojis, make the colors magenta. Three separate edits, one run, every page.

This guide covers how the template is built, how to point it at your own file, how to change the font across a whole document, and which prompts survive a batch.

What an AI PDF editor does differently

Most PDF work is repetitive by nature. A change that takes ten seconds on page one takes ten seconds again on page two, and a forty-page deck turns a small decision into an afternoon.

A bulk PDF editor solves the volume problem. An AI PDF editor also solves the instruction problem, because you are not recording an action or configuring a rule. You are writing a sentence, and an AI document editor reads it the way a colleague would.

The difference shows up on the edits that are tedious to specify and easy to describe:

  • Swapping every typeface in a document to a single font
  • Recoloring headings, accents, and highlights to a new brand palette
  • Stripping emojis, icons, or decorative marks out of a working file
  • Flattening a mixed-format handout into one consistent look
  • Rebranding a template that was written for a different company
  • Turning an internal document into something you can post

Each of those is one sentence to a person and dozens of clicks to a mouse. That gap is the whole reason to batch the job.

It suits the documents that were built once and then kept getting reused:

  • Pitch decks and sales one-pagers going out under a new brand
  • Onboarding guides and internal handbooks
  • FAQ sheets and templated answer documents
  • Event programs, menus, and printed handouts
  • Course material and worksheets that need a consistent look

If you have ever done bulk image editing on a folder of photos, the mental model is the same. One instruction, many inputs, one pass. You can batch edit PDF files exactly that way.

How to edit all PDF pages at once

The template is deliberately small. Two nodes, one prompt, one run. Open it from the Picsart Flow template library and the canvas arrives already wired, so there is nothing to connect.

Step 1. Load your document

The Document node sits at the left of the frame and holds the file. The template ships with an eight-page FAQ document loaded, and a pager in the corner counts through it.

  • Click the Document node to swap in your own PDF
  • Use the arrows or the thumbnail filmstrip to move between pages
  • Check the page count before you go further, because that count is what gets processed

Step 2. Let the pages fan out into the batch

The Document node wires straight into a Batch node, and that connection is what turns one file into many inputs. Load an eight-page PDF and the Batch node reads “items 8” with all eight pages tiled inside it.

  • Every page becomes its own item in the batch
  • The badge on the node tells you exactly how many items are queued
  • The Add more button lets you drop in extra pages or images alongside the document

Step 3. Write one instruction for the whole document

The prompt bar runs along the bottom of the canvas. Whatever you write there applies to every item in the batch, so the instruction has to make sense on any page in the file.

The template’s own prompt stacks three edits into one line:

The template prompt

Change the font of the document to Times New Roman, remove all emojis, and make the colors magenta.

Notice what it does not do. It never names a page, never points at a specific heading, and never describes content that only exists once. Every clause is true of the whole document.

A batch-safe instruction usually has three parts:

  • The property you are changing, named plainly, such as the font or the accent color
  • The value you want it changed to, as specifically as you can put it
  • The things that must stay untouched, spelled out rather than assumed

Step 4. Set the model and the output

Under the prompt bar sit the controls for the run. The template comes preset, so you only touch these if you want something different.

  • Model is set to GPT Image 2
  • Size is set to 1024×1024
  • Quality is set to High
  • The run button shows the credit cost before you commit, which reads 40 on the eight-page default

Step 5. Run it and review the stack

Hit run and the batch processes as a set. Review the results together rather than one at a time, because what you are checking is consistency.

  • Scan for pages where the instruction landed differently
  • Look hardest at the densest pages, since they carry the most for the model to hold
  • Check that the clauses you wrote as protections actually held
  • Download the set or keep it on the canvas and wire it into the next step

How to change the font in a PDF across every page

Font is the first clause of the template’s prompt, and there is a reason it comes first. It is the change people most often want across a whole document and the one that punishes you hardest for doing it manually.

Change the font in a PDF one page at a time and you make the same decision over and over, with a fresh chance to be inconsistent each time. Batched, it is one sentence.

Three things make a font instruction land cleanly:

  • Name the typeface, or name the category. “Times New Roman” is unambiguous. “A clean sans serif” is a category, and the model will pick within it, which is fine when you care more about the feel than the exact face.
  • Say what happens to the hierarchy. Without a word about heading sizes, a font swap can flatten the structure. Tell it to keep the relative sizes.
  • Protect the wording. A typography instruction should never be an invitation to rewrite. Say the words stay as they are.

Font swap, structure protected

Change all text in the document to Times New Roman. Keep the relative heading sizes, the paragraph breaks, and the wording exactly as they are.

If the file arrived carrying three or four typefaces, which happens to any document that has been passed around, the same instruction doubles as a cleanup. One named font in, every inconsistency out.

Five prompts to run across a whole document

The prompts below are written to survive a batch. Each one describes a property of the document rather than a detail on a single page, and each one says what to leave alone.

Brand color swap

Change every heading to deep navy and every body paragraph to dark charcoal. Change all accent marks, bullets, and highlights to warm gold. Keep the layout, the spacing, and the wording exactly as they are.


Single typeface

Change all text in the document to a clean sans serif typeface. Keep the relative heading sizes, the paragraph breaks, and the wording unchanged.


Strip the decoration

Remove all emojis, icons, colored highlights, and decorative marks. Keep the text content and the layout identical to the original.


Full rebrand

Apply a warm cream background with charcoal text throughout. Change every accent color and link color to burnt orange. Do not change any wording, spacing, or layout.


Serious to social

Make the document bolder and more graphic. Increase the visual weight of every heading, add strong color blocking behind section titles, and keep all body text legible and unchanged in wording.

Start editing your PDF pages with AI

Open the Bulk edit all pages of a PDF template, drop in the file you have been putting off, and write the change as one sentence. Run it once and watch the whole stack come back consistent. Build it on the Picsart Flow canvas.
