Split PDF.
Extract Pages.

Yes. SmartFiles processes all PDF splitting locally in your browser. Your files are never uploaded to a server, ensuring that your sensitive documents remain private and secure on your own device.

No. Our tool works entirely within your web browser. There is no software to install and no extensions required.

No. Since the splitting happens directly in your browser's memory, we have no access to your data, and we do not store, view, or analyze your files.

We utilize powerful WebAssembly modules within your browser to handle PDF operations. This turns your browser into a local desktop-like application that splits your documents without needing an internet connection to process files.

SmartFiles is completely free, with no accounts, sign-ups, or subscriptions required. You can split PDFs as often as needed.

Yes. Our tool allows you to extract specific page ranges, individual pages, or split by a set interval, giving you full control over how your document is divided.

No, the splitting process extracts your PDF pages content-as-is, preserving the original quality, text, images, and formatting of every page included.

Yes. Since SmartFiles runs in your web browser, you can use our PDF splitter on iPhones, iPads, Android devices, and desktop computers without needing to install an app.

Because a PDF counts pages from the first page of the file, not from the first page bearing a printed number. A document with a cover sheet and a contents page therefore has its first printed page numbered 2 or 3, which means the two numbering schemes are offset. This is the detail that catches people out when extracting a range, and confirming the numbering visually before you select is the reliable way to avoid extracting the wrong page and sending it to someone.

Page content survives perfectly, but anything belonging to the document as a whole does not. Text remains selectable and searchable, images keep their original resolution, and vector graphics stay sharp at any zoom level, which is what makes extraction genuinely lossless for the pages you keep. Internal links that pointed to a page which was not extracted no longer resolve, so a document with a clickable table of contents may lose that navigation, and bookmarks and outline entries are not rebuilt for the extracted pages. Digital signatures covering a whole file may also stop validating, for the same reason they do after a merge.

No, the pages are copied as-is, so nothing is re-encoded and nothing degrades. Interactive form fields also remain on the pages that contained them and keep working. This is what makes extraction a safe operation for legal, financial and official documents where fidelity to the original matters, and it means you can run the tool repeatedly on the same source to pull out several different sections while the source stays available for the next request.

Extract first. Pulling out the two pages that matter and compressing that short extract gives a much better result than compressing forty pages and trimming it afterwards, because each step is easy to verify on its own and the compression engine is not spending effort on pages you were going to discard. The same logic applies to reordering: extracting a range and then merging it back into the position you want is far more reliable than trying to reason about a complex multi-step operation in one go.

It depends on what you extracted and what it is for. Document metadata, including the original title and author, is copied rather than rewritten, which can occasionally make a small extract's file properties misleading. Watch for mixed page sizes too: extracting pages from a landscape insert into a portrait document produces a file that prints awkwardly even though every page is technically correct. For a formal submission, keep page numbering intact and include any front matter a reviewer might expect; for an emailed document, being as small as possible while staying legible is usually the better priority.

Because sending only the relevant pages is both considerate and safer. Nobody wants a forty-page attachment for a one-page request, and the pages you did not need to send are no longer in the recipient's copy. It is also simply faster and better than compressing an entire long document hard enough to fit a size limit, because you are no longer degrading content that was never going to be read.

Select from the visual overview rather than from arithmetic, and check the page count and order in the preview before you download. A one-minute check at that point prevents the most common and most annoying outcome, which is an extract that looks right in the preview and is missing something on closer inspection. When you need a large portion of a document rather than a small part, extracting a range is considerably more efficient than selecting pages one at a time and produces exactly the same result.
