Why use ShiftTools to convert images to PDF?

A4, Letter & A3 support

Choose the exact paper size you need. Each image is scaled to fill the page while keeping its original aspect ratio — no cropping, no distortion.

Instant, no waiting

PDF generation happens in milliseconds using your device's CPU. No server queue, no upload progress bar — the file downloads the moment you click.

100% private

Your images never leave your device. No server receives your files, no account is needed, and the tool works offline after the page loads — safe for sensitive documents.

Drag to reorder pages

Arrange your images in any order before converting. Drag the thumbnail cards into sequence — page numbers update live. Works on touch screens too.

JPG, PNG, WEBP & HEIC

Mix and match image formats in the same PDF. Convert iPhone HEIC photos, web WEBP images, scanned PNGs, and classic JPGs all at once into one unified document.

High quality or compressed

Print-ready at 95% JPEG quality, or shrink the output by up to 80% with the Compressed mode — perfect for email attachments, form uploads, or messaging apps.

Frequently asked questions

Everything you need to know about converting images to PDF with ShiftTools.

To convert images to PDF with ShiftTools, simply drag and drop your JPG, PNG, WEBP, or HEIC files onto the upload zone — or click “browse files” to open your file picker. Your images appear as thumbnail cards in the page strip below. Select your preferred page size (A4, Letter, or A3), choose Portrait or Landscape orientation, pick between High Quality or Compressed output, and click “Download PDF.” The PDF is built entirely inside your browser using the Web APIs — no files leave your device, and the download starts instantly.
Yes, that is exactly what this tool is designed for. You can add as many images as you need — there is no enforced limit — and each image becomes one page in the output PDF. The thumbnail strip lets you see all pages at a glance. You can drag the cards to rearrange the page order before downloading, and remove individual images by clicking the × button on any card. This makes it perfect for combining scanned document pages, photo collections, receipts, or presentation slides into a single shareable file.
Your images are never uploaded anywhere. ShiftTools runs the entire image-to-PDF conversion locally in your web browser using the HTML5 File API, Canvas API, and client-side JavaScript. No file is transmitted over the internet, no account is required, and no personal data is collected. This means the tool works completely offline once the page has loaded — making it safe for sensitive documents like ID scans, medical records, or confidential business paperwork.
ShiftTools Image to PDF supports all major raster image formats: JPEG / JPG, PNG, WEBP, and HEIC / HEIF (on compatible browsers). You can mix formats in the same PDF — for example, combine a PNG logo page with JPG photo pages. SVG and animated GIFs are not supported as PDF page sources.
These are standard paper sizes used when printing or viewing PDFs:
  • A4 (210 × 297 mm) — international standard, used in Europe, Asia, and most of the world.
  • Letter (8.5 × 11 in) — standard in the United States and Canada.
  • A3 (297 × 420 mm) — twice A4, ideal for wide layouts, posters, and engineering drawings.
Your image is scaled to fill the selected page size while maintaining its aspect ratio.
High Quality embeds images at near-original resolution (95% JPEG quality) — ideal for printing or archiving. Compressed applies heavier JPEG compression, reducing file size by 60–80% with minimal visible quality loss — ideal for emailing, uploading to web forms, or messaging apps. You can switch modes and re-download without re-uploading your files.
Yes. After adding images, the page strip shows each image as a numbered thumbnail. Simply drag and drop the cards into your desired sequence — page numbers update automatically. You can remove pages with the × icon and add more with the + button. Drag-to-reorder works on both desktop and touch devices.
Yes, ShiftTools Image to PDF is fully responsive and works on iOS (Safari) and Android (Chrome) without any app installation. Tap the upload area to open your camera roll, configure settings, and tap “Download PDF.” HEIC photos from iPhone are supported — Safari converts them automatically via the File API.
