Question 1

這個 PDF 轉 TIFF 轉換器是免費的嗎？

Accepted Answer

是的。在這裡把 PDF 轉換為 TIFF 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。

Question 2

我的 PDF 檔案會被上傳到任何地方嗎？

Accepted Answer

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.

Question 3

PDF 轉 TIFF 有檔案大小限制嗎？

Accepted Answer

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.

Question 4

把 PDF 轉換為 TIFF 會損失品質嗎？

Accepted Answer

It depends on your selected settings and codec path. Many engines can write either lossy or lossless output for TIFF, so you can usually increase quality if this file is your final version.

Question 5

可以一次把多個 PDF 檔案轉換為 TIFF 嗎？

Accepted Answer

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.

Question 6

PDF 轉 TIFF 能在手機、Mac 或 Chromebook 上使用嗎？

Accepted Answer

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.

Question 7

Why do some conversions take longer on first run?

Accepted Answer

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.

Question 8

I converted a file and the output is blank or unusable. What should I check?

Accepted Answer

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.
