How do I merge multiple PDFs into one PDF?

Drop the PDFs onto the page, drag the cards to set the output order, optionally rotate or pick a page range for each, then click Merge into one PDF. The merged file downloads to your device immediately - nothing is uploaded.

Can I mix images and PDFs in the same merged file?

Yes. Drop any combination of PDFs and images (JPG, PNG, WebP, HEIC, GIF, BMP, SVG). Each image becomes one page; each selected PDF page is copied in. The cards keep their dropped order until you drag them.

Are my files uploaded to a server?

No. The merge runs entirely in your browser using WebAssembly. Your files never leave your device - the page works offline once it has loaded, and you can verify this in your browser's network panel.

How do I reorder PDF pages before merging?

Each file is a draggable card. Click and drag the handle on a card (or press Tab to focus it and use Space + arrow keys) to move it to a new position. The merged PDF reads top-left to bottom-right in the order shown.

Can I select specific pages from a PDF instead of merging all of it?

Yes. Multi-page PDFs show a 'Pages' field on their card. Type a comma-separated list with ranges - for example 1-3,5,7-9 - and only those pages are included in the merged output, in the order you specified.

Can I rotate pages before merging?

Yes. Every card has rotate-left and rotate-right buttons that step by 90 degrees. The thumbnail rotates live so you can preview the result. Image cards rotate the bitmap before embedding; PDF cards apply the rotation to the embedded page.

Does merging compress or re-encode the source PDFs?

No - the source PDF pages are embedded as-is, preserving the original page content stream. Images are embedded losslessly (JPG bytes are kept verbatim when rotation is 0; other formats are encoded as PNG, also lossless).

What page sizes are supported?

Auto (each page sized to its content for a zero-whitespace PDF), A4 (210x297mm), Letter (8.5x11in), and Legal (8.5x14in). Combine any size with portrait, landscape, or auto orientation, and pick a margin of None, 0.25in, 0.5in, or 1in.

Can I merge HEIC photos from my iPhone?

Yes. HEIC files are decoded locally by a WebAssembly module, converted to a canvas, and embedded into the merged PDF. Drop them alongside any other image or PDF.

Is there a file size or count limit?

No server-side limit - the tool never uploads anything. A warning shows when the total exceeds 200 MB because very large batches can stress browser memory, especially on phones. Most users can comfortably merge dozens of files at a time.

Does this work on iPhone, iPad, or Android?

Yes. The interface is responsive and the drag handles use touch-aware pointer events. Safari 16.4+ on iOS, Chrome on Android, and any modern mobile browser are supported.

Can I password-protect the merged PDF?

Not directly from the merge tool today. After downloading the merged PDF you can add a password with any PDF security app, or open it in Preview (macOS) / Acrobat to set permissions.

Will the merged PDF keep clickable links and bookmarks from the source PDFs?

Embedded page content (text, links inside the page) is preserved. Outline-level bookmarks from the source PDFs are not carried over to the merged document - this is a limitation of the browser-side merge.

Why use this instead of a desktop PDF merger?

No install, no signup, and your files never leave your computer. The tool is also reordering-first, which most desktop apps treat as a secondary feature - here drag-and-drop is the primary interaction.
