Merge PDF is a free online tool that lets you combine multiple PDF files into one perfectly ordered document — entirely in your browser, with no uploads and no server processing. Whether you are assembling a multi-chapter report, combining scanned invoices, merging presentation decks, or stitching contracts together before signing, this tool handles it all in seconds.
Once you drop your PDFs onto the page, every single page from every document is rendered as a visual thumbnail so you can see exactly what you are working with before producing the final file. You are not limited to reordering whole files — drag any individual thumbnail to a new position to interleave pages from different sources in any order. Click the trash icon on any thumbnail to exclude that page from the output without touching the originals.
The entire process runs client-side using WebAssembly and pdf-lib, so your documents never leave your computer. This makes it the right choice for confidential contracts, personal records, financial statements, tax documents, medical files, and any sensitive material where uploading to a third-party server is not an option. There is nothing to install, and the tool works on any modern browser — Chrome, Firefox, Safari, and Edge on both desktop and mobile.
Need to go further? After merging, you can compress the result to reduce file size, split it back into separate files, add page numbers, or convert it to Word format — all without leaving this site. iLoveDocsTools is a complete browser-based document toolkit used by students, professionals, legal teams, and small businesses worldwide to handle everyday PDF tasks privately and without cost.
Upload one or more PDF files using the drag-and-drop zone or file picker — you can add files in multiple batches. The tool reads each file with pdf-lib and renders thumbnail previews for every page across all documents in a unified grid. Drag thumbnails to reorder pages in any sequence, mixing pages from different files freely. Click the trash icon to remove any page. When the arrangement looks right, click "Merge & Download". The tool assembles a new PDF with only the visible pages in the displayed order, then triggers a browser download. Source files are never modified.
Upload your PDFs
Drag and drop one or more PDF files onto the upload area, or click "Choose Files" to open the file picker. You can add more files at any time before merging.
Preview every page
After uploading, every page from every document appears as a thumbnail. Scroll through to confirm you have the right files and pages loaded.
Drag to reorder
Click and drag any page thumbnail to move it to a new position. You can freely mix pages from different source PDFs into any order you like.
Remove unwanted pages
Hover over any thumbnail and click the trash icon to exclude that page from the merged output. The original files are never changed.

100% Private — No Uploads
Everything runs inside your browser using WebAssembly. Your files never touch our servers, making this safe for sensitive and confidential documents.
Page-Level Control
Unlike most merge tools that only combine whole files, you can reorder, remove, or rearrange individual pages from different documents before merging.
No Quality Loss
pdf-lib copies pages at the binary level — text, images, fonts, and vector graphics are preserved exactly as in the originals with no re-encoding.
No Install Required
Open the tool and start working immediately — no software to download. Use free for files up to 40 MB, sign up free to raise your limit to 80 MB, or upgrade to Pro for 250 MB per file.
Works Everywhere
Chrome, Firefox, Safari, and Edge on Windows, macOS, Linux, iOS, and Android — the tool runs identically across all modern browsers and devices.
