What is Image to PDF Converter?

Converting images to PDF is one of the most common document workflows — turning a collection of JPEGs or PNGs into a standard PDF document that can be signed, printed, emailed, or submitted to official systems. PDF is the universal document format: it looks identical on every device, can be password-protected, is accepted by virtually every institution, and preserves image quality without the recipient needing any image viewer software.

This tool places each uploaded image onto its own PDF page, maintaining the original aspect ratio while fitting the image within standard paper dimensions (A4 or US Letter). All conversion happens in your browser using the jsPDF library — your photos are never uploaded to any server. Multiple images are combined in your chosen order, and the final PDF downloads instantly.

How to Use Image to PDF Converter

1

Click "Select Images" or drag and drop JPEG, PNG, or WebP files onto the upload area

2

Review the image order shown in the list — drag images to change the page order

3

Choose your page size (A4 or US Letter) and orientation (portrait or landscape)

4

Optionally set image quality: High (larger file), Medium (balanced), or Low (smaller file)

5

Click "Convert to PDF" — the PDF downloads automatically to your device

Privacy First

Every image is processed locally using jsPDF in your browser. No photos are uploaded to or stored on our servers at any point — sensitive documents like IDs and receipts stay on your device.

Reduce File Size

For sharing by email, use the "Medium" quality setting which targets 150 DPI — visually identical to high quality for recipients but reduces file size by 60-70%. For print quality, always use "High".

EXIF Orientation Handling

Photos taken on iPhones and Android phones store rotation information in EXIF metadata rather than physically rotating the image. This tool reads and applies EXIF orientation automatically, so portrait photos will appear correctly in the PDF without you needing to rotate them manually.

Frequently Asked Questions

How many images can I convert at once?
There is no hard limit on image count. However, converting 50+ high-resolution images may be slow due to browser memory constraints. For very large image sets (100+ images), convert in batches of 20-30 and then merge the resulting PDFs using the Merge PDF tool.
Will the image quality be reduced in the PDF?
At the "High" quality setting, images are embedded at full resolution — the PDF will be large but the image will look exactly as it does on screen. At "Medium", images are resampled to 150 DPI (suitable for screen viewing and most printing). At "Low", images target 72 DPI (smallest file, screen viewing only).
Can I control the margin or padding around images in the PDF?
Yes — the page margin setting controls how much white space surrounds each image. A standard 10mm margin leaves a clean border. Set to 0 for full-bleed images that fill the entire page edge to edge.
Why does my portrait photo appear as landscape in the PDF?
Some camera apps embed EXIF rotation data in photos instead of physically rotating the pixels. This tool reads EXIF orientation and applies the correct rotation before embedding. If the rotation is still incorrect, rotate the image in your photo viewer first and re-save, then convert.
Can I add a cover page or title page to the PDF?
Not directly in this tool — it is designed for image-only PDFs. For a cover page, create a title slide in a presentation tool, export it as JPEG, and add it as the first image in the conversion.
Are my photos sent to a server when I convert?
No. All image-to-PDF conversion happens locally in your browser using jsPDF. Your photos are never uploaded, transmitted, or stored on our servers. The conversion runs entirely in browser memory.

How This Tool Works

Each uploaded image file is read as a data URL using the FileReader API. Before embedding, EXIF orientation metadata is extracted using a lightweight parser and applied as a canvas rotation if needed. Each image is then drawn onto an off-screen Canvas at the target resolution, and the resulting image data is embedded into its own PDF page using jsPDF's addImage() method, scaled to fit within the chosen page dimensions with margin. The final PDF is generated as a Blob and offered for download.
