About this tool
Turning a set of photos or scanned pages into a single shareable PDF usually means a desktop app or an upload-based converter. This image to PDF converter builds a PDF from your images directly in your browser using pdf-lib, an open-source PDF library — your images never leave your device. Reorder pages before converting and choose whether each page should fit its image exactly or use a standard A4 or US Letter size.
How to use it
- 1Click the upload area or drag one or more images onto it (JPG, PNG, or WebP).
- 2Reorder images using the up and down arrows — they'll become PDF pages in the order shown.
- 3Choose a page size: fit each page to its image, or use a standard A4 / US Letter size.
- 4Click "Convert to PDF" and download the result.
Common mistakes to avoid
- Expecting a 'fit to image' PDF to print at a standard paper size — choose A4 or US Letter instead if you plan to print it.
- Mixing portrait and landscape images with a fixed page size, which can leave extra white space around narrower images — this is expected, since each image is centered and scaled to fit.
- Forgetting to reorder images before converting, resulting in pages in the wrong sequence.
Use cases
- Combining scanned receipts or documents (photographed with a phone) into one PDF to submit or file.
- Turning a set of photos into a single PDF portfolio or lookbook.
- Converting a screenshot sequence into one document for easier sharing.
Frequently asked questions
Are my images uploaded to a server?
No. Conversion happens entirely in your browser using pdf-lib, an open-source JavaScript library. Your images never leave your device.
What image formats are supported?
JPG and PNG are embedded directly. Other formats like WebP or GIF are automatically converted to PNG in your browser before being added to the PDF.
What does "Fit to each image" mean for page size?
Each PDF page is sized to exactly match its image's dimensions (converted from pixels to points), so there's no extra white space. Choose A4 or US Letter instead if you need a standard, printable page size.
