Turn images into a PDF without re-compressing them
Drop photos, scans or screenshots and get one tidy PDF. Original pixels are embedded as-is — no server round trip, and no second round of JPEG compression to soften your scans.
The quality loss nobody warns you about
Most “JPG to PDF” tools decode your image and re-encode it inside the PDF. For a JPEG that means a second generation of compression artefacts on every edge; for a scan of small print, it means the difference between legible and merely suggestive. It happens because the server pipeline normalises images to whatever its PDF library prefers.
Here the original file is embedded into the PDF as a stream, untouched. The page is built around it: choose A4, Letter or a page that fits the image exactly, set a margin, and the image is placed at its natural proportions — never stretched, never cropped.
How to build the PDF
- Add the imagesSelect several at once; each becomes one page in the order shown. Drag to reorder by removing and re-adding.
- Choose the pageA4 and Letter centre the image with your margin; “Fit image” makes the page exactly the image size, which is what you want for screenshots.
- ExportOne PDF, images untouched, ready to send or print.
Practical details
Phone photos are usually 4:3 or 16:9, so on an A4 page they will sit with white bands above and below — that is correct, not a bug. A 4000 × 3000 photo on A4 at 12 pt margin prints at roughly 340 DPI, comfortably above print quality. Screenshots are typically 72–144 DPI by nature; choose “Fit image” so they are not blown up to A4 and softened.

FAQ
Do my images lose quality?
No. JPG and PNG are embedded without decoding, so no new compression artefacts are introduced. The PDF is larger than the sum of the images only by the page structure.
Can I put several photos on one page?
Not in this tool — one image per page. Lay out a collage first if that is the goal, then convert the collage.
Does it support HEIC from an iPhone?
Not yet. Export to JPG from Photos first (Share → Copy → Save as JPEG, or Settings → Camera → Formats → Most Compatible). Cameras and browsers do not agree on HEIC decoding, so converting it reliably is a separate job.
