Images to PDF
Combine JPG, PNG, and WebP images into a single PDF. Reorder pages, pick paper size and orientation, fit or fill. Runs entirely in your browser.
Runs in your browser — nothing uploaded
Combine many photos into a single PDF without uploading them anywhere. Useful for batching receipts and forms before sending, assembling reference photos into a contact sheet, or turning a phone-camera scan of a document back into a real PDF.
Private by design — your data never leaves your device
How to use it
No account, no upload — it all happens on your device.
1
Drag JPG, PNG, or WebP images into the dropzone — or click to pick them.
2
Reorder thumbnails with the left/right arrows; remove with the X button.
3
Choose page size (A4, Letter, Legal, or 'Fit image'), orientation, fit mode, and margin.
4
Click 'Build PDF' to download the combined file.
Layout options at a glance
Pick the page geometry that matches the job.
| Page size | When to use | Tip |
|---|---|---|
| A4 | International forms, EU paperwork, most general use. | Pair with 'Auto' orientation so landscape photos rotate the page. |
| Letter | US printing, US business forms. | Same width as A4 but slightly shorter — pages won't get cut on a US printer. |
| Legal | US legal documents, long contracts. | Margins matter — use the slider so signatures land in safe areas. |
| Fit image | Each image keeps its native size and ratio. | Best for sharing originals at full resolution. Skips orientation and margin. |
Common workflows
- Phone-scanned receipts → expense PDF. Drop all photos at once, set page to A4 (or Letter), Auto orientation, Contain so nothing is cropped.
- Quick contact sheet. Use Fit image so each photo lives at native size — useful for sharing with a designer or printer.
- Cover photo + content pages. Reorder so a portrait cover sits at the top, set Auto orientation, and landscape content pages rotate automatically.
Notes on size and quality
- JPGs embed directly. Photos stay at their source quality with no re-encoding. The output PDF is close to the sum of the input file sizes.
- PNGs also embed directly. Transparent backgrounds become white in the PDF.
- Other formats (WebP, AVIF, HEIC where supported) are re-encoded to JPEG at quality 92 before embedding — the only reliable way pdf-lib can embed them.
- To shrink further after building, run the output through the Compress PDF tool.
Frequently asked
What image formats can I turn into a PDF?
JPG, PNG, and WebP work out of the box. Anything your browser can decode (GIF, BMP, HEIC where supported, AVIF on modern browsers) is auto-converted to JPEG before embedding so the resulting PDF stays small.
How do the fit modes change the output?
'Contain' shrinks each image to fit inside the page with whitespace on the short side — the entire image is visible. 'Cover' fills the page completely and crops any overflow. 'Stretch' resizes the image to the page rectangle and may distort the aspect ratio. Pick 'Fit image' as the page size to skip the question entirely — each page becomes the exact size of its image.
Are my images uploaded to a server?
No. The PDF is assembled in your browser using pdf-lib, with each image embedded directly. Nothing leaves your device — close the tab and the images are gone.
