About Image to PDF
What it does
Image to PDF turns one or more images into a single PDF document — each image becomes a page, in the order you choose. It accepts JPG, PNG, WebP and HEIC, and lets you reorder, rotate, and set the page size (fit-to-image, A4 or Letter) before downloading.
How it works
- The PDF is assembled in the browser with
pdf-lib. - JPG and PNG images are embedded directly — no re-compression, no quality loss.
- WebP and HEIC (and any rotated image) are drawn to a canvas and re-encoded once at your chosen quality, since PDF can only embed JPEG and PNG. HEIC is decoded via a lazily-loaded converter so non-HEIC users never download it.
- Page layout (fit / A4 / Letter, orientation, margin) is computed per image and the picture is centered to fit.
Limits
- Max 30 MB per image.
- One image per page in this version; multi-image page grids are planned.
Privacy
Browser-only, like every ChoreCrush tool. Your images are read into memory, converted locally, and downloaded as a blob. Nothing is uploaded.
