pdfAbout PDF to Scanned Look
PDF to Scanned Look is a free, in-browser PDF tool. Apply a realistic scanned-document effect to a PDF with noise, skew, and grayscale options. The page exposes a small surface — input, controls, output — so a first-time visitor can complete the job without reading documentation.
Anyone who works with PDF document workflow on a casual basis — small-business owners sending invoices, teachers distributing course handouts, freelancers sharing scanned receipts — finds PDF to Scanned Look a quick way to get the result. The page loads in under a second, the controls are visible from a single screen, and the result downloads or copies in one click.
PDF to Scanned Look parses your file with Mozilla's PDF.js renderer entirely inside the browser, applies the options you selected, and returns a download. The processing has no network step, which means a slow or intermittent connection does not slow down the work — once the page is loaded, only your CPU and RAM are involved.
Technically, the work is done by Mozilla's PDF.js renderer, loaded as part of the page. Inputs in PDF format are recognised automatically and validated before the engine begins processing. Files up to 200 MB are supported per run; that ceiling keeps browser memory usage stable on a wide range of devices.
Reach for PDF to Scanned Look when you need a predictable result on a single file. The page works on the first visit, the controls are visible without a menu, and the output is delivered the moment the engine finishes.
PDF to Scanned Look sits in a small group of related tools. Useful neighbours include PDF Dark Mode, Flatten PDF, Add Image to PDF, and Resize PDF. They are designed to compose: the output of one is a sensible input to the next, so a multi-step task is usually a sequence of single-click operations.
The download is delivered as `{name}-scanned.pdf` the moment processing completes — no email link, no "your result will be ready in 5 minutes" queue, no expiry timer. The file is generated in your browser and saved by your browser's normal download flow.
The only practical limit is the 200 MB per-file ceiling, which keeps the tool responsive across a wide range of devices. Run the tool ten times in a row, run it ten thousand times — it behaves the same way and produces the same quality of result.
PDF to Scanned Look is honest about scope: it handles a single, well-defined PDF document workflow step. Specialist edge-case work — uncommon formats, very large inputs, or pipelines that need scripting — is what dedicated desktop apps are for. This page handles the common case quickly.
A short note on how PDF to Scanned Look came to look the way it does: every iteration started by watching how someone unfamiliar with the tool actually used it, then removing whatever got in their way. That is why the upload area dominates the screen, the run button is bigger than the secondary controls, and the result panel is unmissable when the job finishes.
If you want to get the most out of PDF to Scanned Look, three small habits help. Drag-and-drop is faster than the file picker once you get used to it. The keyboard shortcut for downloading the result is whatever your browser uses for "save link as," because the result is a normal download. And if you are working on a sensitive file, processing in an Incognito or Private window is a good extra layer — it leaves no trace in browser history when the tab closes.
Common gotchas worth flagging: PDF to Scanned Look only accepts PDF, so if your file is in another format you will need to convert it first. The 200 MB ceiling is per-file, not per-session; you can run as many separate jobs as you like, but a single oversized input will be rejected on load.
PDF to Scanned Look produces deterministic output: the same input plus the same options always produces the same result. That predictability matters when the result has to match an upstream specification or be reproducible later.
PDF to Scanned Look is intentionally narrow in scope so the common case is fast and the result is predictable. If you ever need a variation it does not cover, browse the rest of the catalog — there is a good chance an adjacent tool already exists, and switching between tools is just a matter of opening another tab.
How it works
- 1Open the PDF to Scanned Look workspace above. The interface is a single page, so there is nothing to navigate.
- 2Add your PDF input by dropping it onto the page or browsing for it.
- 3Adjust the options to match what you need. Sensible defaults cover the most common case, so you can usually skip this step.
- 4Hit the run button. Mozilla's PDF.js renderer does the work in your browser tab.
- 5Grab the output named `{name}-scanned.pdf` as soon as the run completes. You can also copy the result instead of downloading if the next tool in your workflow accepts pasted input.
- 6Repeat the process for additional inputs whenever you need to. The page stays loaded, so subsequent runs are quick.

FAQ
Why simulate scanning?
Some workflows require scanned-look documents, or you want a vintage paper aesthetic.
Effect levels?
Light (subtle), Medium (realistic scanner), and Heavy (old photocopy) effects.
Color modes?
Keep color, convert to grayscale, or convert to black and white.
Private?
Yes — runs locally.
File size?
Scanned-look PDFs may be larger because pages become rasterized images.
OCR compatibility?
The effect produces images, not selectable text. Original text layer is replaced.
Does PDF to Scanned Look work in Safari, Firefox, Chrome and Edge?
PDF to Scanned Look works in any modern browser released in the last few years — Chrome, Edge, Firefox, Safari, Brave, Arc and the major Chromium derivatives are all supported. The underlying engine relies on widely-supported web APIs, so there is nothing exotic to install. If you are on a very old browser version and the tool fails to load, updating to the latest release of your preferred browser is the only fix needed.
How fast is PDF to Scanned Look?
Most jobs finish in seconds. Speed scales with input size and with how many CPU cycles your browser tab has available — the engine runs in your browser, so it shares resources with whatever else you have open. For inputs near the 200 MB ceiling, expect anywhere from a few seconds to roughly a minute on a typical laptop. Closing other heavy tabs noticeably speeds things up.
How is PDF to Scanned Look different from desktop apps that do the same thing?
Desktop apps usually have more advanced features but require installation, maintenance and (often) a licence. Paid online tools are convenient but route your file through their servers and gate downloads behind accounts. PDF to Scanned Look sits in between: free, instant, and private, but intentionally narrow in scope. For one-off jobs and the common PDF document workflow operations, it is usually the lowest-friction choice; for highly specialised work, a dedicated app is still the right answer.
Does PDF to Scanned Look ask for any browser permissions?
PDF to Scanned Look 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.
Can I trust the output of PDF to Scanned Look for important work?
PDF to Scanned Look is built on Mozilla's PDF.js renderer, which is the same class of engine used by professional PDF document workflow pipelines. For deterministic operations, the output is byte-identical to what an equivalent CLI run would produce; for operations involving a codec or a model, the result is well within the range of what comparable tools generate. If you have a specific reference output you need to match, run a small test job first to confirm the configuration produces what you expect.
Does PDF to Scanned Look have an API?
PDF to Scanned Look is a browser-only tool by design and does not expose a hosted API. The reason is the same as the privacy story: there is no Favtoo backend doing the work, so there is no service to call. If you need to script the same transformation, the underlying engine (Mozilla's PDF.js renderer) is open-source and can be used directly from your own code.
Do I need to install anything to use PDF to Scanned Look?
No installation is needed. PDF to Scanned Look runs as a normal web page, with no browser extension, no native helper, and no separate desktop client to download. That is partly a privacy choice — extensions can request broad permissions, while a regular page is sandboxed by default — and partly a convenience one: you can use PDF to Scanned Look on any computer you have temporary access to without leaving anything installed on it.
