如何壓縮 SVG 檔案：實現無損品質輸出

SVG（即可擴展向量圖形）是一種獨特的圖像格式，它根據網格上的精確點和線透過數學公式儲存圖像。這與 JPEG 完全相反，JPEG 是基於像素的光柵檔案。此外，由於其可擴展性和可工作的文件大小，這種文件通常用於網頁和圖形設計。

However, users are now commonly compressing this file to improve load times and performance. So, if you’re looking for a compression tool for your SVG files, then you’re on the right page. Learn in this article about the best SVG compression tools and how to effectively use them to optimize your images without sacrificing quality.

第 1 部分：以最小尺寸壓縮 SVG，不會造成明顯的線上品質損失

If you want to compress your SVG files to a minimum size without an obvious quality loss online, the best tool you can use for this is the FVC Free Image Compressor. This tool is 100% free, and compared to other compressor tools that offer free service, this one is an exception as it compresses image files while maintaining their quality.

Step 3. Wait for the conversion process to complete. After that, you’ll see a bar status stating it’s finished. Now, click Download to save your image.

這個 SVG 壓縮工具的最大優點是它在上傳時會執行自動壓縮。此外，其批次功能允許使用者同時壓縮多達 40 個影像檔案。這對於那些有大量需要壓縮的 SVG 檔案的人很有幫助。此外，這些檔案會快速自動減少到最大 5MB，以確保使用它們時的載入效能。最後，除了 SVG 檔案之外，您還可以壓縮其他圖片檔案格式，例如 JPEG、PNG 和 GIF。

第 2 部分：使用專業軟體壓縮 SVG - Adobe Illustrator

如果您需要專業軟體來壓縮SVG文件，Adobe Illustrator將是最佳選擇。該軟體程式以其先進的圖形設計功能而聞名。儘管如此，它還能夠優化和減小 SVG 檔案的檔案大小，同時保持高品質。

以下是有關如何在使用 Adobe Illustrator 時壓縮 SVG 檔案的步驟：

Step 1. On your Adobe Illustrator program, open the SVG file by going to the File tab and clicking the Open button.

Once you’re on the main interface, go to the File tab again and click the Save As button or press Shift-Control-S to save your document.

Step 2. Now, choose Adobe Illustrator.Ai for the file type, set the name of your document, and then press Save.

Step 3. Now, uncheck the Create PDF Compatible File box and check the Use Compression box is checked. Once done, just click OK to save the file reduced in size.

Here you can also use this tool to export SVG to JPG or PNG that you need.

使用者在 Adobe Illustrator 程式中建立 SVG 檔案專案時可以利用此方法。該程式有一個功能，允許用戶在保存檔案之前直接壓縮檔案。然而，這不是典型的 SVG 壓縮工具，它為一堆 SVG 檔案提供批量轉換並具有自動壓縮率，但話又說回來，當您使用此程式時，您可以輕鬆快速地將此類檔案壓縮為在保持品質完整性的同時盡可能減少檔案大小。
