JPG 至 GIF 转换常见问题解答

How do I convert JPG to GIF without losing image quality?
+
Upload your JPG file and the converter applies format-aware quality optimization for GIF. For lossless GIF (PNG, TIFF, BMP) every pixel is preserved; for lossy GIF (JPG, WebP) you can tune the quality factor before download.
Transparency survives when GIF is PNG, WebP, TIFF, GIF, or SVG. Converting to JPG flattens the alpha channel against a white background. If you need transparency in the result, target a transparency-aware GIF instead of GIF=JPG.
Embedded ICC color profiles are read from JPG and re-attached to the GIF output where the format supports it (JPG, PNG, TIFF, WebP). Formats without profile support fall back to sRGB, which keeps colors consistent across most modern displays.
Camera EXIF (ISO, shutter, lens, GPS coords) is preserved by default during JPG → GIF when both formats support metadata. Use the privacy option to strip metadata before download if you need to share images without geolocation.
Yes — drag multiple JPG files into the upload zone and we queue them in parallel. Free users get 100 MB per file; Premium has no per-file cap and runs more parallel workers, so a 200-image batch typically finishes in under two minutes.
For straight format conversion we run the same libpng / libjpeg-turbo / libwebp / ImageMagick pipelines a desktop editor uses, with the same output quality. The difference is parallel batch handling — desktop apps open one file at a time; we accept a batch.
Default is 1:1 — your GIF keeps the pixel dimensions of the source JPG. If you need to resize as part of the conversion, use /resize-image/ after conversion, or chain it with the /image-resize/ utility.
For JPG / WebP, quality 75-85 typically gets the GIF 60-80% smaller than JPG with no visible difference at normal viewing distance. For lossless GIF (PNG, TIFF), expect smaller savings — usually 5-30% via better deflate / LZW compression.
Yes — uploaded JPG files are processed in isolated workers and deleted within minutes. We never read, store long-term, or share the pixel data. The full retention window is documented at /privacy/.
Yes for free up to 100 MB. Premium handles larger inputs (300 MB+) and exotic per-pixel depths (16-bit PNG, 32-bit float TIFF). The pipeline streams rows so memory use scales with row count, not total pixel count.
A JPG with strong existing compression (lossy JPG) often grows when re-encoded to lossless GIF (PNG, TIFF). A lossless JPG often shrinks dramatically when going to JPG / WebP. The ratio depends on image content — photos compress differently from line art.
Yes. The conversion is a format change — copyright on the image content stays with you (or whoever held it on the source JPG). We add no watermark, no metadata stamp, and claim no licence over the GIF output.
