About the Images to PDF
This tool combines several images into a single PDF file, placing one image per page in the order they are added. It accepts any common image format, converts each one internally for reliable embedding, and builds the final PDF entirely in your browser, so your photos are never uploaded to a server — handy for turning phone photos of a paper document into one shareable file, or bundling a batch of receipts into a single PDF for an expense report.
How to use the Images to PDF
- 1
Upload the images you want combined, or drag several in at once.
- 2
Choose 'Fit to each image' to make every page match its image exactly, or pick A4 or Letter for a fixed page size.
- 3
Check the image count shown once the PDF is built.
- 4
Download the combined PDF.
What people use it for
Turning phone photos of a document into a PDF
Photograph each page of a paper document and combine the photos into a single PDF ready to email or file, without a dedicated scanning app.
Submitting a photo assignment or portfolio
Combine several separate image files into one PDF when a form or platform only accepts a single document upload.
Archiving a set of scanned receipts
Bundle a batch of receipt photos into one dated PDF instead of keeping dozens of loose image files.
Why every image is converted before embedding
PDF files can only embed images in specific formats they understand natively, and browser-captured photos increasingly arrive as WebP or other formats a PDF library cannot embed directly. Rather than trying to detect and branch on every possible source format, each image here is first redrawn onto a canvas and re-encoded as PNG, a format every PDF library handles reliably, before being placed on its page. This adds a small, unnoticeable processing step and sidesteps format compatibility problems entirely.
Fit to each image versus a fixed page size
'Fit to each image' sets every page's dimensions to match its source image precisely, so nothing is cropped, stretched or padded with empty space — the natural choice when the images don't need to look like a formal, uniformly sized document. Choosing A4 or Letter instead places every image on a page of that fixed size, scaled down if necessary and centred with a margin, which is generally what you want if the pages will be printed together or need to look consistent when viewed as a document rather than a photo album.
Tips
- Photograph documents straight-on and well-lit for the clearest, smallest resulting PDF.
- Because images embed as lossless PNG, a large batch of high-resolution photos can produce a sizeable file — resize very large photos first if file size matters.
- Add images in the order you want the pages to appear; there is no separate reorder step.
