pdfAbout Add Blank Page
Add Blank Page is the kind of utility you bookmark and reach for when you need it. Insert blank pages into a PDF at the start, end, after a specific page, or at regular intervals. It loads quickly, works on any modern browser, and produces a result you can download or copy in a single click.
The processing pipeline is straightforward: your input is parsed by the open-source pdf-lib JavaScript library, transformed according to the options you select, and serialised back into a downloadable result. Accepted input formats are PDF. The 200 MB per-file ceiling matches what a typical browser tab can handle without paging to disk.
Add Blank Page works well as a bookmarked utility you reach for when you need it. The first visit shows you what the tool does; the second is when you realise it is a low-friction option for the task and worth keeping in your tab list.
The execution model is straightforward: your file is bytes in the tab's memory, the engine reads those bytes, computes the result, and hands the result back to the browser. The transformation happens locally, which is why the tool keeps working when your network connection drops mid-job and why it produces the same result every run for the same input.
Constraints worth knowing about: inputs are capped at 200 MB to keep memory usage in a sensible range, one input is processed per run, and the tool must be loaded over HTTPS for the in-browser engine to work. These are properties of the architecture.
Workflow tip: Add Blank Page pairs well with Add Cover Page and Remove Blank Pages. Other adjacent tools you may find useful are Duplicate Pages and Create Booklet. Because every tool is a separate page, you can mix and match the steps that match your job. Bookmark the ones you reach for the most.
Add Blank Page is shaped around the recurring needs of two audiences: HR teams handling onboarding documents, who use it as a quick utility between bigger tools, and freelancers sharing scanned receipts, who use it as their primary way of getting the job done. Both groups get the same defaults and the same speed.
Once the engine finishes, `{name}-blanks-added.pdf` is offered as an immediate download. There is no preview gate, no email-wall, and no "register to download" intermediary — the file is yours the moment it is ready.
Add Blank Page is built around steady iteration on a small set of options rather than feature creep. Every additional setting attracts a slightly different audience, but a long settings panel makes the common case slower for everyone. The current controls reflect what users of the tool actually use.
From a product perspective, Add Blank Page is one of the simplest possible expressions of "do one thing well." The catalog contains dozens of related tools that each handle a slightly different PDF document workflow task, and every one is a separate page rather than a tab inside a larger app. That separation keeps each tool fast to load and easy to bookmark.
Tips from users who reach for Add Blank Page regularly: process one input first to confirm the settings produce what you expect before committing to a batch; treat the page as the working surface and avoid leaving large jobs running in a backgrounded tab where the browser may throttle JavaScript; and if a particular file fails, check whether the source is intact by opening it in its native viewer — most "tool errors" are actually input errors.
Add Blank Page is built around the moment of need: a focused page you open when you have a specific task, complete the task, and close. The catalog contains many adjacent tools so the same model serves the surrounding parts of a typical PDF document workflow workflow.
If the result is not what you expected, the most common causes are easy to check. Confirm the input is under the 200 MB ceiling — files just above the cap fail silently because the engine refuses to allocate the buffer. Confirm the input is one of the supported formats. And if the page itself feels slow, try closing other heavy tabs to free up memory; the engine runs in your browser, so it competes for the same resources as everything else open.
That is the whole tool. Use Add Blank Page for as long as it stays useful to you, and if it does, the catalog has many more tools built the same way. Each applies the same single-purpose discipline, so the way you used this page transfers to the next one you try.
How it works
- 1Land on the Add Blank Page page. The tool is ready to use the moment the page renders.
- 2Add your PDF input by dropping it onto the page or browsing for it.
- 3Tweak the controls if the defaults are not quite right for your input. The options are kept short and labelled in plain language.
- 4Hit the run button. the open-source pdf-lib JavaScript library does the work in your browser tab.
- 5Download the result as `{name}-blanks-added.pdf`. The file is generated in your browser and saved through your normal download flow.
- 6Repeat the process for additional inputs whenever you need to. The page stays loaded, so subsequent runs are quick.

FAQ
Where can I insert blanks?
At the start, end, after a specific page, or after every N pages (e.g., every 2 pages).
Page size?
Blank pages can match the existing page size or use a standard size like A4 or Letter.
Multiple blanks?
Yes — add 1 to 50 blank pages at each insertion point.
Private?
Yes — processing runs locally.
Duplex printing?
Adding blanks after specific pages helps ensure content starts on the correct side when printing duplex.
Undo?
Use the Remove Blank Pages tool to strip them out later.
Can I use Add Blank Page on iOS or Android?
Add Blank Page runs in any modern mobile browser — Safari, Chrome, Firefox and the in-app browsers in most messaging apps all support the underlying APIs. Performance depends on the device: a recent phone handles typical inputs nearly as fast as a laptop, while older devices may take a few seconds longer near the 200 MB ceiling. The interface lays out cleanly on small screens, so you do not need to pinch-zoom to see the controls.
What is the maximum file size for Add Blank Page?
Inputs are capped at 200 MB per file, which keeps memory usage stable across phones, tablets and older laptops. You can run Add Blank Page as often as you need; every run produces a full-quality result.
Does Add Blank Page support batch processing?
Add Blank Page processes one input at a time by design — it keeps memory usage predictable on lower-end devices and makes results easier to verify. To handle a folder, run the tool once per file; the page stays loaded between runs and remembers your last-used settings, so the second run is essentially instant.
How accessible is the Add Blank Page interface?
Add Blank Page uses native HTML controls wherever possible, which means keyboard navigation, focus rings, and screen-reader labels work the way the platform expects. The drop zone accepts files via the keyboard-accessible file picker as well as drag-and-drop, and result downloads use standard browser download flows. If you spot an accessibility gap, Favtoo treats it as a bug worth fixing.
Which file formats does Add Blank Page accept?
Add Blank Page accepts PDF. If your input is in a format that is not directly supported, convert it first using one of Favtoo's converter tools — every Favtoo converter outputs a file that is a clean input to the next tool in the chain.
Where does my file actually go when I use Add Blank Page?
Your file is processed inside your browser by the open-source pdf-lib JavaScript library. The engine reads the file's bytes from your tab's memory, computes the result, and writes the result back into the tab. You can confirm what the page does by opening developer tools and watching the Network tab during a run — the requests you see are for the tool's static assets only.
Why is my browser prompting me when I open Add Blank Page?
Add Blank Page only needs the standard web platform — file picker access for the inputs you choose to load, and optionally clipboard access if you copy the result rather than downloading it. There is no microphone, camera, geolocation or background-permission request, because none of those are needed for the work the tool does.
