Images to PDF可以处理什么？
Images to PDF 用于在浏览器中转换数据或文件，并清楚显示处理结果和限制。 已核对的功能： Multiple image input, A4 and Letter pages, Configurable margins, Local PDF export.
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.
如何使用？
- 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.

常见错误与修复方法
| 现象 | 可能原因 | 修复方法 |
|---|---|---|
| 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. |

关于Images to PDF的常见问题
Does the Images to PDF upload my input?
No. Processing runs in the current browser tab, and the page does not send tool input to a KitLumi processing endpoint.
What input does the Images to PDF accept?
It accepts one or more JPEG, PNG, or WebP images. The workspace checks the input and reports malformed or unsupported values before it produces a result.
What does the Images to PDF produce?
It produces a downloadable multi-page PDF with image-sized, A4, or Letter pages. Copy and download controls appear when the output format supports them.
What limitation should I know?
Very large images remain memory-intensive even when the final PDF is compact.
