為您提供全面評論：Google Drive 會壓縮照片嗎？

有些網站對插入圖片的寬度和高度有限制。因此，您不可避免地會遇到需要放大或縮小圖片的情況。說到圖片處理，您首先想到的肯定是業界專家 Photoshop。它以其豐富的功能而聞名。對於專業人士來說，Photoshop 無疑是調整圖片大小的理想選擇。但如果您是新手，可能會因為找不到相應的功能而苦惱。

That's okay; we've covered you with our most detailed guide on shrinking an image in Photoshop. If you have a more urgent task, consider another image manipulation tool we recommended in this article.

第 1 部分：如何在 Photoshop 中調整影像大小

首先讓我們看看如何使用 Photoshop 來更改圖像的大小。

請注意，更改圖片尺寸和縮小圖片尺寸的步驟可能略有不同。因此，我們將逐步指南分為兩部分。您將在下一部分中找到有關縮小圖片尺寸的具體指南。

Step 1. Open Photoshop, then go to File > Open to select the image you want to resize.

Step 2. Navigate to Image > Image Size.

Step 3. Enter your desired pixel dimensions, document size, or resolution in the Image Size dialog box..

Step 4. Choose a Resampling Method before confirming.

Bicubic: Ideal for smooth gradients; it calculates average pixel values for precision.

Bicubic Smoother: Best for enlarging images, especially those with noise, resulting in a softer appearance.

Step 5. Click OK to apply the changes.

您現在已成功更改圖片的寬度和高度。但請注意，此操作也可能會增加圖片檔案的大小。因此，在了解寬高比的同時，請務必檢查圖片檔案的大小是否符合您平台的要求。

第 2 部分：如何在 Photoshop 中縮小影像

在本節中，我們將重點放在如何在 Photoshop 中縮小影像的尺寸。

Step 1. Launch Photoshop and navigate to File > Open to choose the image you want to edit.

Step 2. Go to Image > Image Size. This will open the Image Size dialog box.

Step 3. Input the new values for pixel dimensions, document size, or resolution based on your needs.

Step 4. Choose a Resampling Method.

Bicubic: Ideal for smooth gradients; it uses surrounding pixels to generate precise results.

Bicubic Sharper: Recommended for reducing image size while maintaining sharp details. If the image becomes overly sharp, switch back to Bicubic.

Step 5. Click OK to apply the changes and resize your image.

現在，您已成功縮小了原始影像的尺寸。然而，與第一部分的情況一樣，操作完成後，您也會注意到影像檔案的大小發生了顯著變化，這主要體現在壓縮後檔案變得更小了。

It should be noted that the quality of the image may have been lost. If you think it's a bit too much for your viewing pleasure, you can fix it again by using the image enhancer.

使用 Photoshop 調整圖片大小需要相當多的步驟。當你有大量圖片需要處理時，將它們一張一張地拖進 Photoshop 進行編輯非常耗時且繁瑣。幸運的是，我們有另一種批量縮小圖片大小的方法。

以下是在 Photoshop 中批次縮小影像尺寸的方法。

Step 1. First, place all the photos you want to batch compress into a single folder.

Step 2. Launch Photoshop, go to the File menu, select Scripts, then choose Image Processor.

Step 3. Click Select Folder under Select the images to process and import the photos you wish to compress.

Step 4. Photoshop will automatically create a new folder within the original one to store the compressed images.

Step 5. In the File Type section, check Resize to Fit, then specify the maximum width and height for the resized images.
