Convert any image to PDF — free, fast, and private
This image to PDF converter merges multiple images into one PDF document without leaving your browser. It's built for combining screenshots, scanned pages, receipts, or design exports into a single shareable file — with full control over page order and optional password protection.
Supported formats
| Format | Works on | Best for |
|---|
| JPG / JPEG | All browsers | Photos, scans — smallest files |
| PNG | All browsers | Text screenshots, logos, transparency |
| WebP | All modern browsers | Website images — 25% smaller than JPG |
| BMP | All browsers | Windows screenshots |
| GIF | All browsers | Simple graphics (first frame only) |
| TIFF | All browsers | Scanned documents, print work |
| HEIC | Safari 17+ only | iPhone photos (see note below) |
HEIC note: HEIC is Apple's iPhone photo format. Safari 17+ on macOS and iOS can decode it natively. Chrome, Firefox, and Edge cannot — the browser itself doesn't understand the format. If you're on Chrome or Firefox and upload a HEIC file, you'll get a friendly message asking you to convert it to JPG first. Our free
HEIC Converter does that in one click.
How to convert images to PDF — step by step
- Upload your images. Click the upload box or drag your files onto it. They stay on your device.
- Drag to reorder. Each image becomes a page. Drag the tiles to set the order.
- Set a page order using the arrow buttons if you prefer clicking to dragging.
- Add a password on step 3 if you want the PDF protected. Leave blank for no password.
- Click "Download PDF." Your file saves to your computer in seconds.
- Open in any PDF reader. Adobe Acrobat, Chrome, Preview, Edge — all handle it.
That's the whole process. From start to finish, it usually takes under a minute for a normal batch of images.
Why use a browser-based image to PDF tool?
Most free converters make you upload your images to their server. That's fine for a public photo. But what if it's a scanned passport, a bank statement, or a confidential invoice?
This tool works differently. Your images stay on your device. The PDF is built inside your browser using JavaScript. Nothing is uploaded, so there's nothing to leak.
- No server uploads — your images never leave your computer.
- No sign-up — no email, no account, no waiting.
- No file size limit — only your browser's memory limits you.
- Works offline — once the page loads, you can turn off Wi-Fi and still convert.
- Free forever — no ads between steps, no paywall, no watermark.

- Office workers — turn a stack of scanned receipts into a single expense report.
- Freelancers — package design mockups into a client-ready PDF portfolio.
- Photographers — merge a photo shoot into a printable PDF album.
- Anyone who has pictures and needs one document — fast.
Common problems and how to fix them
"My HEIC file won't work"
You're likely on Chrome, Firefox, or Edge — none of them decode HEIC. Convert your HEIC to JPG first with our HEIC Converter, then upload the JPG. On Safari 17+ (macOS or iOS), HEIC works directly.
"The PDF looks too big / images are pixelated"
Images are placed on A4 pages at their original resolution and scaled to fit. If a very small image looks blurry, that's because the source file was small — the converter can't add detail that isn't there. Use a higher-resolution source for best results.
"Some images didn't appear"
Check that your files aren't corrupted. Also, very large images (over 5000 px on a side) may fail on low-memory devices. Try reducing the image size first.
"The converter freezes on many images"
Very large batches (100+ images) can slow down older computers. Try splitting into smaller groups — 20 or 30 images at a time. On mobile phones, stick to under 50 images per PDF.
Is it safe to use this image to PDF tool?
Yes. Here's exactly what happens when you use this tool:
- You pick image files from your computer.
- Your browser reads them into memory.
- The PDF is built inside your browser tab.
- You download the PDF back to your computer.
At no point does any file leave your device. No data is sent to SkillsInsider's servers. No tracking cookies watch your conversion. You can prove it yourself: turn off your Wi-Fi after the page loads, then convert your images. It still works.
JPG vs PNG vs WebP — which is best for PDF?
- JPG — best for photos. Smallest files. Slight quality loss on text.
- PNG — best for text, screenshots, and anything with sharp edges. No quality loss.
- WebP — best for web images. 25% smaller than JPG at the same quality.
- HEIC — best when it works (Safari only). Same quality as JPG, smaller files.
For a PDF, the choice mostly affects file size. If your PDF is too big, re-converting JPG images at lower resolution will shrink it.
Tips for the best results
- Use high-resolution sources. A blurry image stays blurry in the PDF.
- Reorder before export. Fix the order on step 2 — you can't reorder after downloading.
- Use PNG for scanned documents. Text stays sharp.
- Use JPG for photos. Smaller PDF, no visible difference.
- Set a password for sensitive files. Bank statements, IDs, medical records — protect them.
