🖼️ Images to PDF
Combine JPG and PNG images into a downloadable PDF.
Process your document
Select JPG or PNG images and convert them into PDF pages. Large images are scaled down to fit A4-size bounds.
No files selected.
How it works
The PDF is processed in your browser using the open-source pdf-lib library. Documents are not uploaded to OpenToolKit servers. A library script is initially downloaded from a third-party CDN; processing happens locally after it loads.
Limitations and privacy
Files are limited to 30 MB each and 20 files per operation. Memory-intensive documents may fail on older devices. Password-protected or malformed PDFs may not load. The output may not preserve every advanced feature in complex PDF documents. Review the downloaded PDF before relying on it.
For confidential files, remember that the library must load from the CDN on first use. Don't upload documents into other websites to troubleshoot this tool.
More PDF tools
Practical example: Combining scanned receipts
Select two JPG or PNG receipts. The tool makes a PDF containing one page per selected image in selection order.
What to check before using the result
Page dimensions follow the scaled image rather than guaranteed A4 paper dimensions. Very large image files can exhaust browser memory.
Frequently asked question
Does this perform OCR?
No. The pictures remain images and the tool does not recognize text.
