What is Images → PDF?

Turning images into a PDF is a task most people do a handful of times a year — but always in a hurry, and always with slightly sensitive content: passport scans, ID copies, receipts, or contract snapshots taken with a phone. This tool builds the PDF entirely in your browser using pdf-lib, so images never leave your device. JPG and PNG are embedded directly; WebP, GIF, and BMP are transparently re-encoded to PNG in a Canvas before embedding. You can choose A4, Letter, or auto-size pages, set a margin, pick contain vs fill scaling, and reorder the images before assembly.

How to convert images to PDF online

  1. 1Drop images (JPG, PNG, WebP, GIF, BMP) onto the drop zone, or click 'Choose images' and multi-select.
  2. 2Reorder them with the up/down arrows on each tile if needed.
  3. 3Pick a page size (A4, Letter, or auto), orientation, fit mode, and margin.
  4. 4Click 'Build & download PDF'. Your browser generates the PDF locally — nothing is uploaded.

Tips & Best Practices

  • ▸Auto page size makes each page match the image's aspect ratio — perfect for photo albums with mixed portrait/landscape sources.
  • ▸Use 'Contain' to preserve the aspect ratio; 'Fill' will stretch to fill the page and may distort images.
  • ▸72 pt (about 1 inch) is a comfortable default margin for scans; use 0 for edge-to-edge photos.
  • ▸PNG source stays lossless; JPG source keeps its original compression — this tool never re-encodes JPG.
  • ▸For very large batches (hundreds of high-res photos), your browser may run out of memory. Split into smaller batches.

Frequently Asked Questions

Which image formats are supported?

JPG and PNG are embedded directly. WebP, GIF, BMP, and other formats supported by your browser are transparently converted to PNG on your device before being embedded — no quality loss for lossless sources.

Can I reorder the images?

Yes. Each image tile has up/down arrows to reorder. The final PDF follows the on-screen order.

What page sizes are available?

A4, US Letter, and 'Auto' (each PDF page matches the image dimensions exactly). Auto mode is useful for photo albums; A4/Letter with margins is right for scan-style output.

Is my image uploaded?

No. Everything runs in your browser using pdf-lib. Files never leave your device.
