Free Online Image to PDF Converter — Combine Multiple Photos into One PDF
There are many situations where you need multiple images in a single PDF file. Submitting scanned documents to a government office. Sending a portfolio of photographs by email. Attaching a multi-page receipt to an expense report. Creating a photo album. Combining product images for a client presentation. Each of these tasks requires the same thing: a reliable way to turn image files into a properly formatted PDF document.
The OmniWebKit Image to PDF converter does this directly in your browser. Upload any number of images — JPG, PNG, WebP, GIF, or BMP — arrange them in the order you want, choose your page size and orientation, and generate the PDF with a single click. Each image becomes one page in the PDF. The entire process runs client-side using jsPDF — your files never leave your device.
Five page sizes are supported: A4, A3, A5, US Letter, and US Legal. Both portrait and landscape orientations are available. A margin slider controls the whitespace around each image. The quality slider lets you balance between PDF file size and image clarity. Three image fit modes give you control over how each image fills the page.
PDF Page Settings — What Each Option Does
Page Size
| Size | Dimensions | Best used for |
|---|---|---|
| A4 | 210 × 297 mm | Standard international document size — used in most countries for business and personal documents |
| Letter | 216 × 279 mm | Standard US document size — used in the United States and Canada for business and professional documents |
| A3 | 297 × 420 mm | Large format — twice the size of A4. Use for posters, technical drawings, architectural plans, or large photo prints |
| A5 | 148 × 210 mm | Half the size of A4. Use for booklets, handouts, pocket-sized documents, or compact photo books |
| Legal | 216 × 356 mm | US legal format — taller than Letter. Used for legal contracts, government forms, and official documents in the United States |
Image Fit Modes
Fit
The image is scaled proportionally to fit within the printable area (page minus margins). The aspect ratio is always preserved — you never get a distorted image. If the image does not fill the entire page, the remaining space is left white. This is the best choice for most use cases.
Stretch
The image is stretched to exactly fill the printable area regardless of its original proportions. This fills the entire page with the image but may distort it — people and objects could look wider or taller than they actually are. Use this for backgrounds or textures where distortion is acceptable.
Original
The image is placed at its actual pixel size, centred on the page. If the image is larger than the page, it is scaled down to fit. If it is smaller, it is left at its original size and centred on the page with white space around it. Use this when preserving exact pixel dimensions is important.
Page Margin
The margin controls whitespace between the image and the edge of the page. A margin of 20 pt (the default) is standard for most documents. Set it to 0 for a full-bleed layout where the image extends to the very edge of the page. Larger margins work well for framed photo prints or documents that will be bound.
Image Quality
The quality slider controls JPEG compression applied to images when embedding them in the PDF. Higher quality means clearer images and a larger PDF file. Lower quality means smaller PDF file with more visible compression artefacts. At 90% (the default), quality is excellent and the file is significantly smaller than at 100%. For documents where file size matters, try 70–80%.
