🖼️ Images to PDF Converter
Photos and scans → one tidy PDF, one image per page, in your order — assembled on your device with no upload, no watermark, no page limit.
How the images to pdf converter works
Each image is embedded into a PDF page sized to match its dimensions (at your chosen DPI assumption), preserving the original image bytes for JPEGs — no re-compression, so quality is exactly what you supplied. Reorder the list before converting; the output downloads as a single document.
This is the "scan submission" workflow: photograph documents with your phone, load them here in order, download one PDF. Because JPEG bytes are embedded directly rather than re-encoded, the PDF is about the size of the images combined — compress or resize oversized photos first (the image compressor pairs well) if the upload form has a size cap.
Frequently asked questions
What image formats are supported?
JPEG and PNG natively — the two formats pdf-lib embeds directly. Other formats (WebP, HEIC) should be converted to JPEG or PNG first with the image converter, in one local step.
Does converting to PDF reduce image quality?
No — JPEG files are embedded byte-for-byte without re-compression, and PNGs are embedded losslessly. The PDF shows exactly the pixels you provided.
How do I control page order and size?
Images become pages in list order — reorder before converting. Each page is sized to its image's aspect ratio, so portrait photos give portrait pages and nothing gets cropped or letterboxed.
Why is my PDF so large?
The PDF is roughly the sum of its images. Phone photos are often 3–8 MB each; running them through the image compressor or resizer first (also local) typically cuts the result by 80%+ with no visible loss on screen.
Are my photos uploaded?
No — images are read and the PDF is assembled entirely in browser memory. For photographed IDs and documents, that is precisely the point.
