FreNiMi Tools

JPG to PDF Converter

Turn one or more JPG, PNG, or WebP images into a single PDF, without uploading them.

Your images stay on this device.

How to convert images to one PDF

Create a shareable document from scans, receipts, photos, presentation slides, or artwork while keeping the original files on your device.

Select your images

Choose one or more JPG, PNG, or WebP files. You can mix supported formats in the same PDF.

Check the sequence

Images become PDF pages in the order shown. Use the up and down controls beside each file to fix the order before creating the PDF.

Create the PDF

The browser builds one page per image and downloads the completed document without adding a watermark.

Convert JPG, PNG, and WebP without an upload

FreNiMi reads each selected image in your browser and places it on its own PDF page using pdf-lib. The page dimensions follow the image dimensions, which avoids automatic cropping or stretching — open your browser's Network tab while converting and you'll see no image data leave the page.

This is useful for combining photographed documents, design proofs, invoices, screenshots, and class notes into one file that is easier to email or archive. Large images and long batches can use significant device memory, especially on mobile phones — resizing oversized photos first, with the image resizer below, keeps both the process and the resulting PDF more manageable.

Supported formats and behavior

  • JPG/JPEG photos and scans.
  • PNG graphics, including transparent PNG input.
  • WebP images converted by the browser for PDF compatibility.
  • One output PDF with no FreNiMi watermark.

Frequently asked questions

Can I combine different image formats?

Yes. You can mix JPG, PNG, and WebP images in one document.

Are my images uploaded?

No. The selected images are processed in browser memory and the PDF downloads directly to your device.

Will transparency be preserved?

PNG transparency is supported by the PDF library. WebP is converted through the browser and may use a solid background.

Why is the PDF page unusually large?

The page follows the source image dimensions. Resize very large images first when you need more consistent page sizes.

Can I reorder images after adding them?

Yes. Use the up and down controls beside each filename in the list to set the exact page order before creating the PDF.
