Image Compressor

Merge Images to PDF

Combine several images into a single multi-page PDF — without uploading them anywhere.

Multi-page PDFs from images are the common shape of a scanned document, an application packet, a portfolio submission, a printable photo album. This tool lets you drop a batch of images, reorder them with a tap, and build a single PDF you can email or print.

Everything runs in your browser — useful for client work, internal scans, and any document set you'd rather not upload to a third-party converter.

Frequently asked questions

Are my images uploaded?
No. The PDF is assembled entirely in your browser. Each image is embedded as a page in the PDF and the file is offered as a direct download.
Can I reorder the pages?
Yes — each item in the queue has up/down buttons to move it before or after its neighbours. The PDF's page order matches the queue order.
How many images can I merge?
There is no hard limit, but very large batches (hundreds of high-resolution photos) will be slow because every image is decoded in your browser. For batches under fifty images the build is near-instant.
What's the difference between A4 and original size?
A4 puts every image on a portrait A4 page, scaled to fit with a small margin — best for printable documents. Original size makes every page exactly the image's pixel dimensions — best when each image already has its intended size.
Do you preserve image quality?
JPG inputs are embedded byte-for-byte — no re-encoding. PNG and WebP inputs are re-encoded as JPG at quality 85 before embedding, which is the trade-off for using PDF as the wrapper. If you want a pure-PNG document, use the Image to PDF tool with single PNGs.
