Word 转换常见问题解答
What is a Word file?
+
Word (Joint Photographic Experts Group) is the most widely used image format for photographs and complex images. It uses lossy compression to reduce file size while maintaining acceptable visual quality, making it ideal for web use, photography, and sharing images online.
How do I convert Word files?
+
Upload your image using our drag-and-drop area or click to browse files. Select your desired output format, adjust quality settings if needed, and click Convert. Your converted image will be ready for instant download.
Is the image conversion free?
+
Yes, our image converter is completely free for basic use. No account required. Convert your photos between formats instantly. Premium features are available for batch conversion and advanced editing options.
Is there a difference between JPEG and JPG?
+
No, JPEG and JPG are exactly the same format. The only difference is the file extension. JPG became common because older Windows versions required three-letter extensions. Both .jpeg and .jpg files are identical in format and quality.
How does JPEG compression affect quality?
+
JPEG uses lossy compression, meaning some image data is discarded to reduce file size. Higher quality settings preserve more detail but create larger files. For web use, 70-80% quality offers a good balance. For archiving, use higher quality or consider PNG format.
Does JPEG support transparent backgrounds?
+
No, JPEG does not support transparency. If your image has a transparent background, it will be replaced with a solid color (usually white) when converting to JPEG. For images that need transparency, use PNG or WebP format instead.
What is EXIF data in JPEG photos?
+
EXIF (Exchangeable Image File Format) data is metadata stored in JPEG files by cameras and phones. It includes information like date taken, camera model, exposure settings, and GPS location. Our converter can preserve or remove EXIF data based on your privacy preferences.
Is JPEG the best format for photos?
+
JPEG is excellent for photographs due to its efficient compression and universal support. For web sharing and everyday use, JPEG is ideal. For professional editing, consider RAW or TIFF. For web with better compression, try WebP. PNG is better for graphics with text or sharp edges.
Can I resize images during conversion?
+
Yes, our converter allows you to resize images while converting. You can specify exact dimensions, scale by percentage, or fit within maximum dimensions while maintaining aspect ratio. This is perfect for preparing images for web use or social media.
Can I convert multiple images at once?
+
Yes, you can upload and convert multiple images simultaneously. Simply select all the images you want to convert, choose your output format, and we'll process them all. Converted images can be downloaded individually or as a ZIP archive.
