PNG
Portable Network Graphics具備真正 Alpha 透明色版的無損壓縮格式,最初是作為 GIF 的免費替代品而誕生。非常適合用於標誌、螢幕截圖與邊緣銳利的介面美術;用在照片上則相當浪費,因為 JPEG 或 WebP 的檔案大小只會是它的一小部分。

能確保文件在任何地方看起來都一模一樣的格式,因為它會自行攜帶字型、版面配置與色彩資訊。自 2008 年起成為 ISO 標準,也是任何需要列印、簽署或歸檔文件的預設格式。

- PNG is lossless, and PDF can be either. At typical quality settings this lands on lossy and trades size for some quality loss. Keep PNG as a source if you may need a higher-detail version later.
- 預設情況下,PDF 頁面會完全依照你的 PNG 尺寸設定,不做任何裁切或加黑邊——若需要固定頁面大小(如 A4 或 Letter),可在設定中選擇。
關於 PNG 轉 PDF 的常見問題
這個 PNG 轉 PDF 轉換器是免費的嗎?
是的。在這裡把 PNG 轉換為 PDF 完全免費,不需要帳號、沒有浮水印,也沒有每日次數限制。處理在你自己的裝置上完成,因此沒有需要轉嫁給你的伺服器成本。
我的 PNG 檔案會被上傳到任何地方嗎?
For browser-based pairs, your file is read locally and converted by pdf.js in this tab. No file payload is uploaded; you may still see analytics and engine downloads in network logs.
PNG 轉 PDF 有檔案大小限制嗎?
There is no imposed upload cap when it runs in-browser, but each conversion still depends on your device and browser memory. Large videos are the first practical limit, then memory-heavy documents or images.
可以一次把多個 PNG 檔案轉換為 PDF 嗎?
Yes. Drop in several files and each gets its own row; they are processed one after another on your device. You can download them one by one or as one ZIP.
PNG 轉 PDF 能在手機、Mac 或 Chromebook 上使用嗎?
Most modern browsers on Windows, macOS, Linux, ChromeOS, Android and iOS work. Very large videos are often more reliable on desktop or a browser with more memory.
Why do some conversions take longer on first run?
The conversion engine has to download first. Small codec bundles are fast, while ffmpeg is commonly 12–30 MB; later conversions of similar type use the cached engine.
I converted a file and the output is blank or unusable. What should I check?
Start over with default settings, then change one option at a time (quality, bitrate, page size, or codec) to isolate what changed behavior. If it keeps failing, retry with a smaller file and confirm the source format matches the pair.
