PDF Combinerv1.0.0

Combine PDFs and images into a single, downloadable PDF directly in your browser. Process files locally for privacy, avoid uploads, and manage pages with quick actions. Follow the steps below to create a clean, professional document.

Start by selecting files. Click the upload label or drag and drop PDFs, JPGs, PNGs, GIFs, or WEBP files into the upload area. Add multiple files at once to speed up page assembly. The tool automatically detects and skips duplicate files based on a content hash.

Choose a page sizing mode. Select Fit to letter to scale content to 8.5 × 11 inches, or select Keep original aspect to preserve image ratios and adjust page height for each item. Use the live preview to verify layout before export.

Reorder, rotate, or remove pages. Drag thumbnails to change sequence. Use Rotate Left or Rotate Right for orientation fixes. Use Delete to remove any item. Add blank pages when you need separators or signature pages. Keyboard shortcuts are available: Ctrl or Cmd + Z to undo, Ctrl or Cmd + Y to redo, Delete to remove selected pages, R to rotate selected pages, and Ctrl or Cmd + A to select all.

Generate a preview to confirm output. Click Generate Preview to render a stacked mockup that reflects your chosen sizing mode and page order. When ready, click Combine to export a final PDF.

Core logic for sizing is transparent for easy auditing or reuse:

• Letter size in points: width = 612, height = 792.
• Fit to letter: scale = min(612 / originalWidth, 792 / originalHeight); draw size = (originalWidth × scale, originalHeight × scale).
• Keep original aspect: draw width = 612; draw height = 612 × (originalHeight / originalWidth).
• Rotation: apply 90, 180, or 270 degrees around the draw box center before placement.

Download the combined PDF with a file name that includes page count and sizing mode. Reopen the tool at any time; preferences such as sizing mode can persist, while file contents do not, to maintain privacy.

Streamline document workflows by merging mixed files into one well-structured PDF. Save time on packaging, delivery, and archiving while maintaining consistent formatting. The following scenarios show how this tool improves productivity.

• Client deliverables: Combine design mockups, screenshots, briefs, and contracts into a single PDF. Insert blank dividers to separate sections and rotate any sideways scans.
• Academic packets: Merge lecture slides, reading excerpts, and annotated images. Preserve original aspect ratios for charts, graphs, and tall infographics.
• Operations and onboarding: Build training manuals from mixed PDFs and images. Add signature pages as blanks and export a letter-sized packet for printing.
• Receipts and recordkeeping: Consolidate scanned receipts and photos into one file for expense reports. Rotate and delete items to fix orientation and remove duplicates.
• Creative portfolios: Assemble thumbnails, process shots, and final artwork into a review-ready document. Reorder pages to match a curated narrative.
• RFP and proposal responses: Merge forms, certifications, and diagrams into a single file that follows the requested order. Use preview to validate flow before submission.
• Legal and compliance packets: Collect exhibits, photos, and statements into one PDF with clear pagination and consistent letter sizing for printing and e-filing.

Choose Fit to letter when printing is required or when consistent page dimensions matter. Choose Keep original aspect when fidelity to image proportions is critical, such as for product photos or vertical diagrams. Validate the output with Generate Preview, then export with Combine for instant download.

Enhance accessibility and speed. Use keyboard shortcuts for frequent edits, apply ARIA-labeled controls for assistive technologies, and rely on local processing to keep sensitive content on your device. Repeat the workflow to create new packets in seconds without installing software.
