Match image size or choose a document page size?
Match each image when pixel dimensions should define each PDF page. Choose A4 or Letter for printing and consistent paper size; the image is centered and scaled down to fit.
使い方
- Add one or more JPEG, PNG, or WebP files in the order they should become pages.
- Choose Match each image, A4 portrait, or US Letter portrait and set a margin from 0 to 144 points.
- Select Process, verify the page count, and download images.pdf.

一般的なエラーと対処
| 症状 | 原因 | 対処 |
|---|---|---|
| An image is rejected or PDF creation fails. | The browser cannot decode the file, total selection exceeds 100 MB, or one image exceeds the 100-megapixel safety limit. | Convert the source to a valid JPEG, PNG, or WebP and reduce its dimensions or batch size. |
| A small image does not fill the page. | The tool never enlarges images above their decoded dimensions. | Use a larger source or resize it deliberately before building the PDF. |
