Frequently asked questions

Are my PDF files uploaded to a server?

No. Every tool on this site runs entirely inside your browser using JavaScript, so your PDFs are processed on your own device and are never sent to a server. Once a tool's engine has finished loading, which starts the first time you add a file, you can even disconnect from the internet and the work still happens on your device. Nothing is uploaded, stored, or logged.

Is there a watermark, page limit, or sign-up?

No to all three. The tools add no watermark, impose no page or file-count limit as an upsell, and never ask you to create an account. Merge needs at least two files; split and compress work on a single PDF of any length.

Are password-protected PDFs supported?

Not directly. A PDF locked with an open password cannot be read, so the tool will report that the file may be corrupt or password-protected. Remove the password first by opening the file in your PDF viewer with the password and saving an unprotected copy, then run that copy through the tool.

How can I check for myself that nothing is uploaded?

Two ways, and neither takes long. Open your browser's developer tools, switch to the network panel, and watch it while you run a job: you will see the page's own files and the PDF engine load from this site, and no request carrying your document. The blunter test is better still. Open a tool and run one small job online first, so the engine is fully loaded. Then turn off your Wi-Fi and run the job again. It finishes and the download appears, which could not happen if the file had to reach a server.

Does this site show ads, and can they see my documents?

The pages carry ads served by Google, which is what keeps the tools free, and that is the one third party involved. The ad code sees an ordinary page request, the same thing it sees on any site that runs ads. It is not part of the tool pipeline: your file is only ever handed to the PDF engines running in your own tab, those engines send nothing anywhere, and we have verified with a network capture that no file data leaves the device while the tools run. The privacy page covers what the ad system does collect.

What happens to a file I drop on the home page before I pick a tool?

It waits a few seconds in your browser's own storage. Dropping files on the home page is a shortcut that saves them into a small local database on your device; the tool page you then choose reads them out and deletes them straight away, and anything left behind is discarded once it is more than a minute old. None of that round trip leaves your machine.

How do I merge several PDFs into one file?

Open the Merge PDF tool, drop in two or more files, drag them into the order you want (or use the arrow buttons), and click Merge to download a single combined PDF. It all happens in your browser. For step-by-step methods on Windows and Mac, see the guide on how to merge PDF files.

How do I extract only certain pages from a PDF?

Open the Split PDF tool and either click the pages you want or type a range such as 1-3, 7. You can save the selected pages as one combined PDF or as a separate file per page, then download. Nothing is uploaded.

Will merging or splitting reduce quality?

No. Merging and splitting copy pages exactly as they are into the new file, so text stays sharp and searchable and images are untouched. Quality is only lost with workarounds that print or re-scan pages instead of copying them.

Can I merge just a few pages out of each file?

Not in a single step. Merge works on whole files: every page of every PDF you add goes into the result, in the order you set. To end up with a subset, either trim each file first in Split PDF and merge the trimmed copies, or merge everything and then run the result through Split PDF to keep only the pages you want. The second route is usually faster.

Why is my PDF so large?

Usually because it is a scan. A scanner saves each page as a photograph rather than as text, so a color scan at high resolution can reach several megabytes per page. Oversized embedded images and embedded fonts add more. See why is my PDF so large for the full breakdown.

How much can compression shrink a PDF?

It depends on what is inside. Scanned and image-heavy PDFs routinely drop by 70-90% because their images are re-encoded at a resolution suited to screens. Text-only PDFs are already small, so there is much less to remove. Try the Compress PDF tool to see the new size before you download.

Will compressing a PDF make the text blurry?

This tool re-encodes every page as an image, so the text becomes part of the picture: it is no longer selectable or searchable, and very aggressive settings can soften it. At moderate settings it stays easy to read on screen. If you need selectable text at the smallest size, your PDF app's reduce-file-size export is the better fit.

What happens to links, bookmarks, and form fields when I compress?

Compression here rebuilds the document out of page pictures, so anything that was not part of how a page looks cannot make the trip: clickable links, a bookmark outline, and fillable form fields are not carried into the compressed copy. That is the honest cost of the size reduction. Keep your original whenever the document is interactive, and compress a copy only when what matters is how the pages read.

Is there a file size limit?

None is written into the tools, so there is no cap to hit and no upgrade prompt waiting at one. The real limit is your device's memory, because the whole file is held in the browser tab while the work happens. A large scan usually just takes longer on a laptop; an older phone with a lot of apps open may run out of room and reload the tab instead of finishing.

How many files or pages can I process at once?

There is no count limit either. Merge needs at least two files and accepts as many as you add; split, compress, rotate, and PDF to JPG work through however many pages the document has; images to PDF takes as many pictures as you drop in. Memory and patience are the only constraints, and progress is reported page by page so you can see how far a long job has got.

Why does a very large PDF get slow, or fail?

Compressing and converting to JPG draw every page at full size before saving it as an image, which is the most demanding thing these tools do, and all of it runs on your own hardware. On a long document that takes time, and on a device short of memory the browser may give up partway. If a job stalls, pull out a chunk of pages with Split PDF and work through the document in pieces, or move to a computer rather than a phone.

Does it work offline?

Once a tool page and its PDF engines have finished loading, yes. Adding a file starts that load if it has not happened yet, and everything after the engines are in happens inside the tab, so you can disconnect and the job still finishes and still downloads. The safe check is to run one small job first: if it completes, everything the tool needs is loaded. What you cannot do is open the site for the first time with no connection: there is no installed offline app, so a fresh visit still has to fetch the page.

Does it work on phones and tablets?

Yes. The tools run in any modern browser and work the same on desktop, tablet, and mobile, with no app to install. The processing happens on your own device: nothing is uploaded, and once a tool’s engine has finished loading, no connection is needed either.

Is it really free?

Yes, completely free. There is no paid tier, no trial, and no account. The tools are free to use as often as you like.

How do I turn a PDF into JPG images?

Open the PDF to JPG tool, pick a quality, and every page is rendered as a JPG image in your browser. One page downloads as a single image; multiple pages arrive together in a ZIP.

Can I fix a PDF that is sideways or upside down?

Yes. The Rotate PDF tool shows every page as a thumbnail; click a page to turn it, or rotate them all at once. Rotation only updates each page's orientation setting, so quality is untouched.

How do I make a PDF from photos?

Open the Images to PDF tool, drop in JPG or PNG files, put them in order, and download a single PDF with one page per image. Your photos never leave your device.

Which image formats can Images to PDF accept?

JPG and PNG files go into the PDF exactly as they are, with no re-encoding and so no quality loss at all. WebP, GIF, BMP, and AVIF work too when your browser can open them, and those are converted to JPEG on the way in, a small quality cost you are unlikely to notice. Anything the browser cannot decode is skipped, and the tool tells you how many images were left out.

Can I convert only some pages to JPG, or get PNG instead?

No on both counts: PDF to JPG converts every page of the document, and JPG is the only format it writes. If you want one page, extract it first with Split PDF and convert that single-page file. That also gets you a plain .jpg download instead of a ZIP, since a one-page PDF produces one image.

How do I rotate a single page instead of the whole document?

Click that page's thumbnail in the Rotate PDF tool. Each click turns it another quarter turn and a small badge shows how far it has been turned, while pages you never click are left exactly as they were. The two rotate-all buttons are there for the common case of a whole document that came out of the scanner sideways.
