Merge PDF

No. This free PDF merger runs 100% in your browser with no server uploads. Your files are never uploaded anywhere - all merging, rendering, and processing happens entirely on your device. Merge PDF files without uploading to any server.

Combine PDF and images into one PDF - supports PDF, JPEG (.jpg/.jpeg), PNG, and WebP. PDFs are merged page-by-page preserving vectors and quality. Images are scaled to fit A4-sized pages and centered. WebP images are converted to JPEG during the merge since PDF does not natively support WebP.

PDF files up to 50MB each, JPEG up to 15MB, PNG up to 20MB, and WebP up to 10MB. The total combined size across all files cannot exceed 200MB.

There is no hard page limit. You need at least 2 selected pages - select specific PDF pages to merge with full flexibility. The practical limit depends on your browser's available memory. Files with hundreds of pages work fine on most devices.

Yes. Reorder PDF pages online free by dragging thumbnails. All pages from all uploaded files appear in a single grid - drag any thumbnail to any position to interleave pages from different documents freely.

Yes, two ways. Deselect a page's checkbox to select specific pages to merge (excluded pages stay visible but faded). Or hover over a thumbnail and click the red delete button to permanently remove it.

Everything is saved to your browser's IndexedDB - uploaded files, page selections, rotations, and merged output. Refreshing restores everything exactly as you left it. Click Clear All to remove all stored data.

No. PDF pages are copied directly, preserving all vectors, text, and image quality. Images (JPEG, PNG, WebP) are embedded at their original resolution, scaled to fit A4 dimensions.

Drag and drop PDFs and images directly onto this online merger without uploading to any server. The area highlights when files are dragged over it. Click Add Files to browse, or use Back To Files after merging to return to the file grid for editing. Multiple files can be added at once.

Every page of every uploaded PDF is rendered as a visual thumbnail directly in your browser. Images (JPEG, PNG, WebP) are shown directly. All thumbnails are displayed at a uniform size with the filename and page number below each one.

Drag individual page thumbnails to reorder PDF pages freely across all files. This PDF merger with page reorder lets you interleave pages from different documents or rearrange pages within a single document.

Click the checkbox on any page thumbnail to select specific pages to merge. Use Select All and Deselect All buttons in the toolbar for bulk actions. Deselected pages appear faded. At least 2 pages must be selected to merge.

Type a range like "1-4, 3-8" in the toolbar and click Apply to select only those pages by their position. This is faster than clicking individual checkboxes for large documents.

Hover over a page thumbnail and click the rotate button to rotate it 90 degrees clockwise. Click multiple times for 180 or 270 degrees. Rotation is applied during the merge process directly in your browser.

Hover over a page thumbnail and click the red delete button to permanently remove it. A confirmation dialog appears before deletion. If all pages of a file are deleted, the file is automatically removed.

Combine PDFs and images into one PDF file in your browser. Each image is scaled to fit an A4-sized page (landscape-aware) and centered. WebP images are automatically converted to JPEG during the merge process.

Per-file limits protect your browser from running out of memory: PDF 50MB, JPEG 15MB, PNG 20MB, WebP 10MB. The total combined limit across all files is 200MB. Files exceeding these limits are rejected with a clear error message.

Enter a custom name in the Filename field in the top bar. Invalid characters are automatically stripped. The .pdf extension is added automatically if omitted. If left empty, the file downloads as "merged.pdf".

Merge and Download are separate actions. Click Merge to process the selected pages — the container switches from Input to Output view showing the merged PDF. Click Download when ready to save the file. Click Back To Files to return to the file grid for further edits before re-merging.

During merging, a spinner overlay appears over the container with a "Merging All Files..." message. Once complete, the container switches to Output view displaying the merged PDF with page count and file size shown in the label.

After merging, the same container switches to Output view and renders the merged PDF page by page with drop shadows on a gray background. Scroll to inspect every page before downloading. Click Back To Files to return to the input grid.

Your uploaded files, page selections, rotations, and merged output are saved to your browser’s IndexedDB. Refreshing the page restores everything exactly as you left it. Click Clear All to remove all stored data.
