PNG to PDF
For phone photos (JPG/HEIC), JPG to PDF gives a much smaller file.
Screenshots and diagrams stay sharp
Most “image to PDF” tools recompress everything as JPG to save space. That's fine for photos, but screenshots, charts and scanned handwriting get blurry halos around text and lines. This tool puts your PNGs into the PDF as-is, without recompression, so they look exactly like the originals and transparent areas stay transparent.
Page size
- Same as image — each page matches its image exactly; ideal for turning screenshots into a flip-through document. Under “Image resolution”, pick 96 dpi for ordinary screenshots, 144 dpi for Mac/Retina screenshots and 300 dpi for scans to get a realistic physical size.
- Fit to A4 (auto orientation) — wide images go on landscape pages, tall ones on portrait pages, with margins. Good for printing or submitting. Small images aren't blown up.
- Fit to A4 portrait — every page portrait.
File size and formats
Since PNGs go in untouched, the PDF is roughly the size of the PNG files combined. Photos are large as PNG — use JPG to PDF for those. Non-PNG images (JPG, WEBP…) are converted to PNG, but quality already lost to JPG compression doesn't come back. Reorder with ▲ ▼, and use Merge PDF to combine the result with other PDFs. Images are never uploaded.
Frequently asked questions
The PDF is too large.
For photos, JPG to PDF is the better fit. You can also shrink an existing PDF with Compress PDF (text becomes part of the image).
How do transparent areas look?
PDF viewers show them on white, but if you place the page over other content, it stays transparent.
Do iPhone HEIC photos work?
Yes. They're converted to PNG, but photos get large that way, so JPG to PDF is recommended.
