Frequently Asked Questions

How many images can I convert at once? ▼

There's no hard limit — you can upload as many images as your browser's memory allows.

What image formats are supported? ▼

JPG/JPEG, PNG, and WebP are fully supported. GIF and TIFF may work but are not officially supported.

Will the image quality be reduced? ▼

The tool preserves your original image quality. Use the Compress PDF tool afterwards if you need a smaller file.

How the Conversion Works

jsPDF creates the PDF document in your browser. Each image is read via the FileReader API and embedded as a full-page visual element. Choose between fitting pages to image dimensions (preserves aspect ratio), standard sizes (A4/Letter for printing), or add custom margins for a document-like appearance. JPEG, PNG, and WebP are all supported. HEIC files from iPhones should be shared as JPEG first. All images stay in your browser — nothing is uploaded.

For the best multi-image results: upload all images at once, use the drag-and-drop reorder interface to arrange them correctly, then convert. This is far faster than any approach requiring software installation. After creating the PDF, run it through Compress PDF if image-heavy output needs size reduction for email or upload.
