Image to PDF

📖 Tool Introduction

A tool for combining a batch of images into one PDF. Select or drag them in, put them in order, and one click produces a PDF. JPG and PNG are supported and can be mixed freely, with the order following the list from top to bottom.

The long edge can be capped: original size is sharpest but heavy, while 1200 to 2000 pixels balance appearance against file size, which helps when sending or archiving. Page orientation can follow each image or be forced uniformly to landscape, so presentations do not end up with a mix of portrait and landscape pages.

Images are scaled proportionally to fill the page and are never stretched out of shape. When done you see the image count and output size before downloading. Everything happens locally in the browser, with no upload to any server.

A few common jobs have a direct recipe. Combine several receipt photos from a phone into one PDF for reimbursement, merge scanned identity documents into a single submission, gather a set of screenshots into a briefing document, or turn photos from an album into a digital collection. The default long edge cap of 1600 pixels stays sharp enough on screen while keeping the file to a sensible size; choose original size when printing, or drop a step lower when sending to someone else.

One last note: images are embedded in the PDF as they are, with no additional recompression, so if you feed in already compressed pictures the result keeps exactly that quality, neither worse nor better. Start from the original images if you want the best possible outcome.

Why order matters: the PDF is built page by page from the top of the list down, so the first image becomes the first page, with no cover and no table of contents. Put the invoice first for reimbursement material, or the identity document first for a submission, and do not expect to rearrange afterwards; either sort it here or generate again. The up and down arrows exist for exactly this, and ten seconds of arranging saves redoing the whole thing.

✨ Key Features

• Combine any number of images, with JPG and PNG mixed freely
• Reorder with up and down arrows; the PDF follows the list exactly
• Four long-edge caps to balance sharpness against file size
• Orientation follows the image or is forced uniformly landscape
• Images scale proportionally to fill the page and never distort
• Local browser processing, images never uploaded

🚀 How to Use

1. Click the upload area to pick images, several at once, or drag them in
2. Use the up and down arrows to arrange the order
3. Choose a long-edge limit and page orientation
4. Press start and wait for the progress bar
5. Press download to save the PDF

⚠️ Things to Note

• More images mean a bigger file: At original size, high resolution photos can produce a very large file, so consider capping the long edge
• Very large images hit memory limits: A single huge image or too many at once can fail, so process in batches
• Only JPG and PNG are supported: Formats such as WebP or HEIC may not decode in some browsers
• Transparency becomes white: Transparent PNG pixels render as a white background in the PDF
• Nothing is kept on a server: Output stays on this device and a refresh means processing again
