Which image formats can I convert to PDF?

JPEG, PNG, WebP, and GIF are all supported. WebP and GIF are converted to JPEG internally before embedding, so they display correctly in all PDF viewers.

Is there a limit on how many images I can add?

There is no hard limit. The practical constraint is your device's available memory. Most modern devices handle dozens of large images without difficulty.

Where does image processing happen?

All processing happens locally in your browser using pdf-lib. Your images stay on your device.

What is the page size in the output PDF?

Each page is sized to match its source image exactly, so the PDF preserves the original dimensions without scaling or cropping.

Technical specification

Algorithm or formula: pdf-lib creates a new PDF document, embeds each image via embedJpg or embedPng, and adds a page sized to the image. WebP and GIF are first re-encoded to JPEG through the Canvas API because pdf-lib does not embed those formats directly.
Browser API or library: pdf-lib 1.17 (lazy-loaded). Canvas 2D API for WebP and GIF preprocessing.
Input limits: Each image up to 50 MB and 50 megapixels. No hard cap on image count; practical limit is device memory.
Output: Single PDF (.pdf) document with one image per page, downloaded as a blob.
Known limitations: No OCR or text layer is added (output is image-only PDF). Page orientation matches the source image, so mixed portrait and landscape inputs produce mixed-page PDFs.
