AI Tools Finder · July 11, 2026
Need to merge a batch of images — phone photos of receipts, scanned document pages, screenshots — into a single PDF file to email or print? You don’t need to install any software or upload your images to some random website. Do it right in your browser, and your images never leave your device.

Why use a tool that runs locally?
Most “image to PDF” sites out there make you upload your images to their server. For receipts, ID documents, or internal files, that’s an unnecessary risk — your images could end up stored or indexed somewhere.
The Merge Images → PDF tool processes everything 100% in JavaScript, right in your browser: there’s no step where your data gets sent anywhere, and it even works offline once the page has loaded.
4 steps to merge images into a PDF
- Add images — drag and drop, or click to select multiple images at once (JPG, PNG, WebP, GIF, BMP, and more).
- Reorder them — drag each image, or use the ▲▼ buttons to change the page order in the PDF.
- Adjust the settings — choose paper size, orientation, and compression level (see below).
- Click “Create PDF” — name the file and download it. Done.
Settings worth knowing about
| Setting | When to use it |
|---|---|
| A4 / Letter size | When you need to print on standard paper |
| Fit to image | When you want the PDF page to match the image dimensions exactly, with no extra margins |
| Portrait / Landscape | Pick the page orientation that matches your images |
| Add white margin | Adds white space around the image for easier viewing |
| Downscale + Quality | Shrinks the PDF file size — handy for emailing (which usually caps at 20-25MB) |
Tip for shrinking file size: phone photos are often 4000px+ and quite heavy. Setting “Downscale” to
≤ 1600pxand quality to~75%typically cuts the file size 5-10x, with almost no visible difference when printed on A4.
Frequently asked questions
How many images can I merge? There’s no hard limit — it depends on your device’s RAM. A few dozen images is usually very fast.
What about PNGs with a transparent background? They’re automatically placed on a white background so they don’t turn black when printed.
Will I lose quality? Images are embedded as JPEG at the quality level you choose. Keep it at 100% to preserve maximum sharpness, or lower it if you need a smaller file.
