Images to PDF

Combine images into one PDF: reorder, choose A4 or fit-to-page, set margins and orientation.

图片与 PDF 都在你的浏览器里生成,不上传服务器

把图片拖到这里,或点击选择(可多选)

顺序即为 PDF 的页码顺序,添加后可用按钮调整

PDF 设置

提示:图片会按页面比例等比缩放并居中,不会拉伸变形;「自适应」模式下每页尺寸等于该图片本身,适合扫描件存档。

图片转 PDF 的常见用法

报销与材料提交。很多单位要求把发票、行程单、身份证正反面、银行流水合并成一份 PDF 上传。用手机拍完直接拖进来,选 A4 + 10mm 边距,顺序用按钮调好即可——不需要装任何软件。

扫描件归档。如果是文档扫描件(画面本身就是纸面比例),选「自适应图片尺寸」+「不压缩」最合适:每页尺寸等于图片本身,不额外留白,也不会被重采样。若原图是手机拍摄的大照片,建议长边压到 1600~2400px,PDF 体积能小一个数量级。

A4 与边距怎么选。A4 是最保险的默认值,绝大多数打印机与阅读器都按 A4 处理。边距留 10mm 可以避免打印时被裁掉边缘;如果图片本身就是整页扫描、不想再缩放,用「自适应」更合适。

关于清晰度。图片嵌入 PDF 时会按你选择的长边上限重采样一次(仅在不压缩时保持原像素)。文字类图片(合同、发票)建议保留更高分辨率,照片类可以放心压到 1600px。

Privacy note:PDF 完全在你的浏览器里生成,图片不会上传到任何服务器。发票、身份证、合同这类敏感材料也可以放心处理,可在开发者工具 Network 面板核验没有任何文件上传请求。

FAQ

Will the generated PDF have searchable text?

No. Turning images into a PDF essentially pastes the pictures onto PDF pages; there is no text layer inside, so the text cannot be selected, copied or searched. For an editable and searchable PDF you need OCR, or export from the original document.

What is the maximum number of images?

There is no hard limit; in practice it depends on your machine's memory. One run of no more than 100 images is recommended; if generation gets slow, compress the images first and then convert.

What if the generated PDF is too large?

Setting 'compress large images' to a long edge of 1600px (the default) usually shrinks the size noticeably; if it is still big, run the originals through our 'image compression' tool first, then convert.

Can HEIC iPhone photos be used?

Not directly - browsers cannot decode that format. Convert them to JPG first with our 'HEIC to JPG' tool (photos are processed locally in the browser, not uploaded), then convert to PDF.
