Key Features

Why Use This Image to PDF Converter?

🔒

Browser-side processing — your images never leave your device — The PDF is generated entirely in your browser using jsPDF. No image data is sent to any server at any point. This makes it completely safe for passport photos, ID documents, medical records, financial statements and any other sensitive images that you would not want uploaded to a third-party server. There is also no file size limit imposed by server upload restrictions.

↔

Drag to reorder pages before converting — After adding images, drag the thumbnail cards to arrange them in any order. The page number badge on each thumbnail updates live to show the new position. The PDF will have pages exactly in the order shown. This is the most requested feature absent on basic image-to-PDF tools which process files in upload order only.

📄

5 page sizes with auto orientation — A4, Letter, A3, A5 and Legal. Auto orientation detects whether each image is wider or taller and sets the page orientation accordingly — so a landscape photograph becomes a landscape page and a portrait photo becomes a portrait page, without any manual switching. Override to force all pages to portrait or landscape if needed.

📸

Multiple formats: JPG, PNG, WebP, GIF, BMP — Any image format your browser can display is supported. Mix formats in the same PDF — combine a JPG photo with a PNG screenshot in one document. PNG files with transparent backgrounds are composited on white. WebP and GIF frames are extracted via canvas. All are embedded as JPEG in the PDF for compact file size.

⚙️

Quality and margin controls — The JPEG quality selector lets you trade file size against image quality: 95% for print-quality output, 85% (default) indistinguishable from lossless for most use cases, 70% for email attachments, 50% for maximum compression. The margin control sets page margins in mm (default 10mm, set to 0 for bleed-to-edge photos).

Guide

JPG, PNG and WebP to PDF — Which Format, Which Settings?

JPG to PDF — best for photographs

JPG is the most common format for converting photos to PDF. For photographic images, JPEG compression is ideal — 85% quality is visually indistinguishable from lossless but reduces file size by 60–70%. Use “Contain” fit mode for photos so the entire image is visible within the page margins. A 10mm margin on A4 is standard for document-style output. For print-quality output (sending to a print shop), use 95% quality and no margin for bleed-to-edge printing.

PNG to PDF — screenshots, graphics and diagrams

PNG files are common for screenshots, diagrams, charts and graphics with text. PNG supports transparency — this tool renders transparent areas on a white background when converting to PDF. For screenshots from a mobile device (portrait, approximately 9:19 aspect ratio), A5 portrait page size is a good match. For desktop screenshots (16:9 landscape), use A4 or Letter landscape. The 85% JPEG quality setting maintains text legibility in screenshots — use 95% if small text must remain sharp.

How to combine multiple images into one PDF

Add all images at once (or in batches) using the file picker or drag and drop. Each image becomes a page. Drag thumbnails to arrange pages. Use Auto orientation so portrait images get portrait pages and landscape images get landscape pages within the same PDF. This is common for scanning documents with a phone camera — photograph each page, add all images here, reorder if needed, and download as a single PDF to send by email or upload to a document system.
