How do I combine several photos into one PDF in the right order?

After dropping the images in, the number beside each item is its page number in the PDF; use ↑ and ↓ to reorder and × to remove, with up to 50 images per document. Choose A4 with automatic orientation and 10 mm margins so that landscape and portrait pictures each land on a suitably oriented page, then click Create PDF to download the file.

Does converting images to PDF reduce photo quality?

JPEG photos usually do not lose any quality: when they have 1 or 3 color components and EXIF orientation 1, they are embedded byte for byte, identical to the original file. Other formats are converted to JPEG at a default quality of 92. Choosing the lossless option stores the exact original pixels instead, but the resulting PDF becomes noticeably larger.

What page size does the generated PDF use?

A4 measures 210×297 mm, which is 595.28×841.89 points, and Letter measures 8.5×11 inches. Each image is scaled proportionally and centered inside the chosen margins, so nothing is cropped or stretched. With image-sized pages the conversion uses 96 dpi, so a 1200×800 pixel image produces a page of 900×600 points, which prints at about 12.5×8.3 inches on paper. Margins apply only to A4 and Letter pages.

Example

Input

Three generated samples: 1200×800, 800×1200, 1600×900 · A4 · automatic orientation · 10 mm margins

Example result

images.pdf with 3 pages: pages 1 and 3 in landscape A4, page 2 in portrait A4, images centered proportionally

The samples are PNGs and are embedded as JPEG at quality 92; uploaded JPEG photos are embedded unchanged when eligible, with quality identical to the original.

Technical details & limits

The page writes the PDF 1.4 structure itself: catalog, page tree, one content stream and image object per page, and a cross-reference table. JPEGs with 1 or 3 color components and EXIF orientation 1 are embedded as-is with DCTDecode; PDF readers ignore EXIF orientation, so oriented photos are rotated upright and re-encoded as JPEG. Lossless mode compresses RGB pixels with the browser's CompressionStream for FlateDecode. Image-sized pages use 1 px = 0.75 pt (96 dpi); A4 is 595.28 × 841.89 pt. Transparent areas are filled with white.

About this tool

Combine up to 50 images into one PDF locally in your browser, one image per page. Pages can be A4, Letter or match each image's size; A4 and Letter support automatic, portrait or landscape orientation and 0, 10 or 20 mm margins, with images centered proportionally. Reorder or remove images with buttons. Eligible JPEGs are embedded as-is without recompression, and other formats are converted to JPEG or embedded losslessly. The PDF is generated by the page itself; images are not uploaded.

How to use

Drop, choose or paste images, up to 50 at a time.
Choose page size, orientation, margins and embedding mode, and reorder pages with ↑ ↓.
Click Create PDF to download.

Input & output

Input: Up to 50 JPEG, PNG, WebP, AVIF, BMP or GIF (first frame) images, each at most 50 MB.
Output: One PDF with one image per page; a single image keeps its original file name.
Limits: No OCR, encryption, page numbers or bookmarks; existing PDFs are not compressed, and several images are not placed on one page.

Notes

The whole PDF is built in memory, so split very large batches. For a smaller file, shrink images with the compressor before converting.
