Resize PDF Pages

Runs in browser PDF Editing & Annotation

Put every page (or a selection) on a new page size, keeping proportions, filling the page or stretching, with automatic orientation. Content is scaled as vectors, so text stays sharp and selectable.

How are watermarks, page numbers and page sizes changed in a PDF?

A watermark, header, footer or page number is content drawn onto each page — text or an image appended to the page's content stream, or added as a stamp annotation — so it becomes part of the page like the original text, printed and copied with it. Page size and margins are separate: ISO 32000 defines them through the MediaBox and CropBox rectangles, so resizing a page or adding a margin changes those boxes and scales or offsets the existing content rather than redrawing it.

Frequently asked questions about Resize PDF Pages

What is the difference between Fit, Fill and Stretch?

Fit keeps the whole page visible with the same proportions (it may leave white bands), Fill scales until the page is covered (edges may be cut), Stretch distorts the content to the exact size.

Does resizing reduce quality?

No. The page is embedded as a vector form and scaled mathematically; text and lines stay vector graphics at the new size and are never turned into pixels.

Can I scale by a percentage?

Yes — choose "Scale" and enter a factor such as 50% or 200%; the page size and its content scale together.

Is my PDF uploaded to a server?

No. The file is opened and processed by your browser with WebAssembly and JavaScript; nothing is sent to Mutqan Soft or anyone else. Close the tab and the file is gone. Downloading the result needs a free account — no subscription, no payment.

Can I use it on a password-protected PDF?

Yes, if you know the password: the file list asks for it once and every operation then works on the decrypted pages. The output is saved without a password unless you protect it again.

Technical notes

Each source page is embedded as a form XObject (embedPages) and drawn onto a new page of the target size with the computed scale and offset; the source /Rotate is re-applied so the visual result matches. Non-selected pages are copied unchanged.
