Images → PDF
Combine one or more images into a single PDF — each image becomes one page.
How to Use
- Drop one or more images into the input area, in the order you want them in the PDF.
- Pick a page size: A4 (210×297mm, international standard), Letter (8.5×11", U.S.), Legal (8.5×14", U.S.), or "Fit each image" (each page matches its image exactly).
- Pick orientation: portrait (taller than wide) or landscape (wider than tall).
- Adjust JPEG quality — lower values shrink file size at some cost to image fidelity.
- Click Make PDF — the file generates entirely in your browser and downloads automatically.
- Each image becomes one page of the PDF.
Notes
Frequently Asked Questions
How are images embedded in the PDF?
JPEG images are embedded directly using DCTDecode (PDF's JPEG container) — no quality loss. PNG images are re-encoded to JPEG for smaller output, with the quality setting you choose. If you need lossless PNG embedding for graphics with transparency or sharp edges, you'll need a different tool (most browser-based image-to-PDF tools convert to JPEG).
What page size should I use?
A4 (210×297mm) for international audiences and most of the world. U.S. Letter (8.5×11") for U.S.-only use. Legal (8.5×14") for legal documents. "Fit each image" uses each image's exact dimensions as the page size — useful when images are diverse sizes and you don't want letterboxing or stretching.
Will the PDF be searchable?
No — image-to-PDF embeds images, not text. The PDF will contain visual content but no selectable or searchable text. For OCR (image-to-searchable-text PDF), use the OCR Extract tool to pull text out, or use a desktop tool like Adobe Acrobat that includes integrated OCR.
How big will the PDF be?
Roughly the sum of the JPEG-compressed image sizes plus a small overhead. A 10-page PDF with high-quality scans (q=0.95) might be 30MB; the same pages at q=0.7 might be 5MB. The 'Fit each image' option produces the smallest files because no resizing/recompression happens for images already JPEG.
Can I add page numbers, headers, or watermarks?
Not in this simple converter. For added text, watermarks, or headers, generate the basic PDF here and then post-process with a more advanced PDF tool (Adobe Acrobat, PDFescape, or our PDF info viewer).
Is the PDF generated in the browser?
Yes. The conversion runs entirely client-side using a JavaScript PDF library — your images are never uploaded to a server. You can safely combine sensitive documents (tax forms, medical records, financial statements) without exposure.
