PNG 至 GIF 转换常见问题解答

How do I convert PNG to GIF without losing image quality?
+
Upload your PNG file and our converter applies format-aware quality optimization for GIF output. For lossless targets (PNG, TIFF, BMP) every pixel is preserved bit-for-bit; for lossy targets (JPG, WebP) you can tune the quality factor (default 90) 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, pick a transparency-aware target instead of GIF.
Embedded ICC colour profiles are read from the source PNG and re-attached to the GIF output where the format supports it (JPG, PNG, TIFF, WebP). Formats without profile support fall back to sRGB with a soft-proof step.
Camera EXIF (ISO, shutter, lens, GPS) is preserved by default during PNG -> GIF when both formats support metadata. Use the privacy toggle to strip metadata before download if you want to share images without geolocation or device-fingerprint exposure.
Yes — drag multiple PNG files into the upload zone and they queue in parallel. Free tier accepts 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 straightforward format conversion we run the same libpng / libjpeg-turbo / libwebp / ImageMagick pipelines a desktop editor uses, at the same quality. The difference is that desktop tools open one file at a time; we accept a batch and run them in parallel on server-side workers.
Default behaviour is 1:1 — your GIF output has the same pixel dimensions as the source PNG. If you need to resize as part of the conversion, use /resize-image/ after, or chain the operations with the /image-pipeline/ utility.
For JPG / WebP, quality 75-85 typically yields a GIF 60-80% smaller than the PNG with no visible difference at normal viewing distance. For lossless GIF (PNG, TIFF), expect smaller savings — usually 5-30% via better deflate / LZW compression than the source already had.
Yes — uploaded PNG files are processed in isolated workers and deleted within minutes. We never read, store, or share the pixel data. The full retention window is documented at /privacy/.
Yes for free up to 100 MB. Premium handles much larger inputs (300 MB+) and exotic per-pixel depths (16-bit PNG, 32-bit float TIFF, HEIF 10-bit). The pipeline streams pixel rows so memory use scales with row count, not total pixel count.
A PNG file with strong compression (heavily lossy JPG) often grows when re-encoded into a lossless GIF (PNG, TIFF), and a high-bitrate lossless PNG often shrinks dramatically when going to JPG/WebP. The ratio depends on the image content (photos compress differently from line-art or screenshots).
Yes. The conversion is a format change — copyright on the image content stays with whoever held it on the source PNG. We add no watermark, no metadata stamp, and claim no licence over the GIF output.
