Sending scanned documents as a stack of JPGs looks unprofessional and is annoying to open. A single PDF is the universal way to share paper. Here's how to turn photos or scans into a proper PDF in under a minute.
Why PDF and not just a ZIP of images?
- **One file** to attach, print or archive.
- Renders identically on every device.
- Universally accepted by governments, banks and job portals.
- Searchable if you OCR later.
Convert in the browser
Open [Image to PDF](/tools/image-to-pdf), drop your JPG / PNG / HEIC images in, drag to reorder, and export. The tool preserves aspect ratio and picks a page size that fits.
For scanned documents
1. Photograph each page in even light against a dark background.
2. Crop tightly to the paper edges.
3. Convert to grayscale if it's text-only — files shrink 3-5×.
4. Run through [Image to PDF](/tools/image-to-pdf).
5. If it's still large, [compress the PDF](/tools/compress-pdf).
For photo portfolios
- Keep images at 2000-2400 px on the long edge (retina-crisp, not oversized).
- Use consistent aspect ratios.
- Export at 90% JPG quality — invisible loss, half the size.
Privacy note
Every image stays on your device. Nothing is uploaded, so it's safe for IDs, passports, tax documents and anything else you wouldn't post publicly.
