Image to PDF

Purpose

Combine multiple JPG, PNG or WebP images into a single PDF, with control over page size (fit-to-image or A3/A4/A5/Letter/Legal), orientation and image order. Runs locally in your browser; images are never uploaded. Free, unlimited file count, no watermark. Ideal for turning phone-shot contracts, receipts and notes into a PDF for expense submission or archival; combining ID photos into a single document; building photo albums.

Steps

1. Drag or pick multiple images (JPG / PNG / WebP)
2. Review the thumbnail grid
3. Drag thumbnails to reorder pages
4. Pick page size: "Fit image" (each page equals the source image), or a standard sheet (A3/A4/A5/B4/B5/8K/16K/Letter/Legal)
5. Pick orientation: "Portrait" or "Landscape"
6. For fixed sheets, further pick image alignment (centered/stretched)
7. (Optional) Enable "Auto-rotate" so landscape images get landscape pages
8. Click "Process"
9. The generated PDF downloads automatically

FAQ

Will my images be uploaded?

No. The image-to-PDF wrap-up uses browser-local pdf-lib; images are read into memory and embedded directly into the new PDF — no upload, no outbound requests.

What are the size/count limits?

Per-image practical ceiling is ~50MB. There's no hard count limit; 100 images of ~5MB each on an 8GB-RAM machine work stably. Pre-compress large images via imgbox first for smoother handling.

Will image quality drop?

With "Fit image", images are embedded without re-encoding — quality is fully preserved. For fixed sheets, scaling may visually shift the appearance, but the underlying pixels are still the original data.

What if the output PDF is bigger than the source images combined?

PDF containers add metadata overhead, and multiple high-res JPGs make the total roughly equal to sum of inputs. To shrink, pre-compress images via imgbox, or run the output through the Compress tool.

Do you support HEIC (iPhone photos)?

Not directly — only JPG/PNG/WebP. Convert HEIC to JPG with imgbox first.

Use cases

• Combine phone-shot receipt photos into one expense PDF for finance
• Stack front-and-back ID photos into one PDF for online verification
• Merge per-page contract photos into a complete archive PDF
• Build a travel photo album PDF for sharing with family
• Assemble design sketches into a single PDF for client review

Tip

For contract scanning, use a "document scanner" app (or your phone's built-in scanner) for perspective correction and cropping first — it beats raw photos. For A4-sized submissions, pick fixed A4 + center, not "Fit image".
