Question 1

Are my PDF files uploaded to a server?

Accepted Answer

No. Every tool runs inside your browser tab using JavaScript. The file you pick is read from local disk into memory, edited there, and written back out as a download. Nothing is transmitted, so there is no upload queue and nothing for us to store or delete.

Question 2

Is there a file size limit?

Accepted Answer

There is no artificial limit — the practical ceiling is your device's available memory. Files above roughly 50 MB will show a warning because rendering page thumbnails and rewriting the document takes noticeably longer on phones and older laptops.

Question 3

Why can't I open a password-protected PDF?

Accepted Answer

Encrypted PDFs cannot be parsed without the password, so the other tools detect the encryption and stop with a clear message instead of failing silently. Open Unlock PDF, enter the password you normally type to open the file, and download the unrestricted copy — then merge, split, compress or convert it as usual.

Question 4

How much smaller will my file get after compression?

Accepted Answer

It depends on what is inside the PDF. Scans and photo-heavy documents often drop by half or more because their images are re-encoded at a lower quality. A text-only PDF is already compact, so savings there are small and the output can occasionally be slightly larger.

Question 5

Do I need an account, and is it really free?

Accepted Answer

No account, no email, no trial. Because processing happens on your device there are no per-file server costs, so the tools are free to use as often as you like and the output carries no watermark.

Question 6

Can I convert a PDF to an editable Word document?

Accepted Answer

Yes. The PDF to Word tool extracts the text layer of your PDF and rebuilds it as a .docx file with headings, bold and italic runs and paragraph flow preserved. It runs entirely in your browser, so the document is never uploaded. Complex layouts such as multi-column pages, tables and images are flattened into plain paragraphs, and a scanned PDF has no text layer to extract, so it needs OCR first.

Question 7

Can I turn PDF pages into JPG or PNG images?

Accepted Answer

Yes. The PDF to Image tool renders every page to a JPG, PNG or WEBP file at screen, standard or print quality and lets you download a single page or all of them together in a ZIP archive. Rendering happens on your device, so nothing is uploaded.

Question 8

Can I make a PDF from photos or scans?

Accepted Answer

Yes. Image to PDF accepts JPG, PNG, WEBP, GIF, BMP and AVIF images, lets you reorder them, and writes one page per image. Choose A4 or Letter pages to centre each image with your chosen margin and orientation, or fit-to-image so the page matches the photo's own dimensions.

Question 9

Can I add a password to a PDF?

Accepted Answer

Yes. Protect PDF encrypts the document with the standard PDF security handler using AES-256 or AES-128, so any reader will ask for your password before opening it. You can also decide whether printing and text copying stay allowed. The encryption runs in your browser, so neither the file nor the password ever leaves your device — and because there is no copy on a server, a forgotten password cannot be recovered.

Question 10

Can I sign a PDF without printing it?

Accepted Answer

Yes. Sign PDF lets you draw a signature with your finger or mouse, type your name in a handwriting style, or upload a photo or scan of your signature. Drag it onto the page you need, resize it, and download a signed copy. The signature and the document are only ever handled inside your browser, so nothing is uploaded.

Question 11

How do I fix a sideways scanned page?

Accepted Answer

Open Rotate PDF, drop the file in, and rotate individual pages left or right from the thumbnail grid — or rotate every page at once. Rotation is stored as page metadata, so text and image quality are untouched.

Question 12

Does it work on a phone or tablet?

Accepted Answer

Yes. The layouts, drop zones, and thumbnail grids are touch-friendly and adapt to small screens. Very large documents will be slower on mobile hardware than on a desktop.

Question 13

Does it work offline?

Accepted Answer

Once the page has loaded, the tools keep working without a connection because the PDF engine is already running in your browser.
