Image to PDF

About Image to PDF Converter

This tool converts images to PDF format. You can convert single or multiple images into one PDF file. Supports various image formats including JPG, PNG, GIF, BMP, and WebP. All conversions happen in your browser for privacy and security.

What image formats are supported?

This tool supports all common image formats including JPEG, JPG, PNG, GIF, BMP, WebP, and more. You can mix different formats in a single PDF.

Can I convert multiple images to one PDF?

Yes! You can select multiple images at once. Each image will become a separate page in the PDF. You can reorder the images before converting to arrange the pages.

How do page size and orientation work?

Page size determines the dimensions of each PDF page (A4, Letter, etc.). Orientation can be Portrait (vertical) or Landscape (horizontal). Images will be automatically scaled to fit the selected page size.

What is the difference between Fit to Page and Fill Page?

Fit to Page scales the image to fit within the page while maintaining aspect ratio, which may leave some white space. Fill Page scales the image to fill the entire page, which may crop parts of the image.

What are the file size limits?

Each individual image must be under 10MB. You can convert multiple images, but the total size should be reasonable for browser processing. The final PDF size depends on image quality settings.

How does image quality affect the PDF?

Higher quality produces better-looking PDFs but larger file sizes. Lower quality reduces file size but may show compression artifacts. Medium quality offers a good balance for most uses.

What DPI should I choose for printing?

DPI (dots per inch) is the print resolution at the placed page size. 300 DPI is the print-shop standard for sharp documents and photos; 150 DPI is fine for everyday office printing; 72 DPI is screen-only and will look soft on paper. After converting, the tool shows the effective DPI of your lowest-resolution image and flags whether the PDF is print-ready. The effective DPI is computed as image pixels divided by the placed width in inches, so a small scan stretched across a full A4 page can fall below your target even if you select 300 DPI.

Why does a very large scan look softer than expected?

To keep conversion fast and the browser stable, images larger than 4096 pixels on the longest side are automatically scaled down to 4096px before they are placed in the PDF. For most page sizes 4096px still exceeds 300 DPI, but if you are printing very large formats or need full archival resolution, check the effective-DPI readout after converting. If it falls below 300, use a smaller page size, add margins, or split the scan.

Is my data safe?

Yes! All image processing happens directly in your browser. Your images are never uploaded to any server. The PDF is created locally on your device.
