Which image formats are supported?

The tool supports JPG, JPEG, PNG, WebP, GIF, and BMP. WebP, GIF, and BMP are converted to PNG internally before embedding into the PDF.

Are my files uploaded to a server?

No. All processing runs in your browser using pdf-lib and the Canvas API. Your images never leave your device.

How many images can I convert at once?

You can combine up to 20 images into a single PDF in one conversion.

What happens to image quality?

JPG and PNG images are embedded directly without re-compression. WebP, GIF, and BMP are drawn to a canvas and exported as PNG, which is lossless.

Can I create a PDF from a single image?

Yes. Upload one image and click Convert to PDF to create a single-page PDF document.

Upload your images
Drag and drop images onto the upload area or click to browse. Supports JPG, PNG, WebP, GIF, and BMP formats. Up to 20 images.
2
Reorder images
Use the up and down arrows to arrange images in the order they should appear as pages in the PDF.
3
Convert to PDF
Click Convert to PDF. Each image is fitted to an A4 page. Non-JPG/PNG formats are automatically normalised before embedding.
4
Download the PDF
Download the generated PDF directly to your device. No account required.

How multiple image formats are handled internally

PDF natively supports two image encoding types: JPEG (via the DCTDecode filter) and lossless deflate-compressed raster (via FlateDecode, used for PNG-compatible data). JPG and PNG images can be embedded directly. WebP, GIF, and BMP have no native PDF representation — they must be converted to a supported format first.

This tool converts WebP, GIF, and BMP to PNG by drawing them onto an HTML Canvas element and exporting the canvas as a PNG blob. That PNG blob is then embedded into the PDF. The conversion is lossless for BMP and GIF (both are lossless formats). WebP may be lossless or lossy depending on the source — lossy WebP converted to PNG will not recover lost information, but the PNG will be a faithful lossless copy of the WebP's decoded pixel data.

Choosing the right tool: Image to PDF vs format-specific converters

This site offers separate JPG to PDF and PNG to PDF tools in addition to this general-purpose Image to PDF converter. The format-specific tools embed images without the intermediate canvas conversion step, which is marginally faster and avoids any potential colour profile shift from canvas rendering.

Use Image to PDF when you have a mix of formats — for example, JPG photos alongside PNG screenshots — and want them combined into one document. Use the format-specific tools when all your images are the same format and you want the most direct path to a PDF. The output quality is identical for JPG and PNG images regardless of which tool you use.

File size expectations and how to reduce them

The size of the resulting PDF is determined primarily by the size of the embedded images. A PDF containing five 2 MB JPG images will be approximately 10–11 MB — the overhead of the PDF structure itself is small (typically under 50 KB).

If the output PDF is too large for email or upload limits, compress your images before converting. The Image Compressor tool on this site can reduce JPG and PNG file sizes significantly before you create the PDF. For JPGs, compressing to quality 80–85% is usually indistinguishable from the original at document viewing sizes while reducing file size by 40–60%.

Another option is to reduce the image dimensions before conversion. A scan at 300 DPI is appropriate for print; for a PDF intended to be read on screen, 150 DPI is sufficient and will produce files roughly one-quarter the size of the 300 DPI equivalent.
