JPG 에 ICO 변환 FAQ
How do I convert JPG to ICO without losing image quality?
+
Upload your JPG file, then our converter applies format-aware quality optimization for ICO output. For lossless formats (PNG, TIFF, BMP) we preserve every pixel; for lossy formats (JPG, WebP) you can tune the quality factor before download.
Does JPG to ICO conversion preserve transparency?
+
Transparency survives when going to PNG, WebP, TIFF, GIF, or SVG. Converting to JPG flattens the alpha channel against a white background — if you need transparency, target a transparency-aware format instead of ICO.
Will my color profile (sRGB / Adobe RGB / CMYK) survive JPG to ICO?
+
Embedded ICC color profiles are read from the source JPG and re-attached to the ICO output where the format supports it (JPG, PNG, TIFF, WebP). Formats without profile support fall back to sRGB.
What about EXIF metadata when converting JPG to ICO?
+
Camera EXIF (ISO, shutter, lens, GPS) is preserved by default during JPG → ICO conversion when both formats support metadata. Use the privacy option to strip metadata before download if you want to share images without geolocation.
Can I batch-convert hundreds of JPG files to ICO at once?
+
Yes — drag multiple JPG files into the upload zone and we queue them in parallel. Free users get 100MB per file; Premium has no per-file cap and runs more parallel workers, so a 200-image batch typically finishes in under two minutes.
How does JPG to ICO compare to Photoshop / GIMP for the same task?
+
For straightforward format conversion we run the same libpng / libjpeg-turbo / libwebp / ImageMagick pipelines a desktop editor uses, with the same quality. The difference is that desktop tools open one file at a time; we accept a batch and run them in parallel.
What resolution and dimensions will my ICO file have?
+
Default behaviour is 1:1 — your ICO output has the same pixel dimensions as the source JPG. Use a separate /resize-image/ step after conversion if you need to downscale or upscale as part of the workflow.
How small can the ICO file get without visible artifacts?
+
For JPG / WebP, quality 75-85 typically gets the file 60-80% smaller than the source JPG with no visible difference at normal viewing distance. For lossless targets (PNG, TIFF), expect smaller savings — usually 5-30% via better deflate / LZW compression.
Are my JPG files private during conversion?
+
Yes — uploaded JPG files are processed in isolated workers and deleted within minutes. We never read, store, or share the pixel data. The full privacy policy and retention window are documented at /privacy/.
Does the JPG to ICO converter work for very large images (50MP+)?
+
Yes for free up to 100MB. Premium handles larger inputs (300MB+) and exotic per-pixel depths (16-bit PNG, 32-bit float TIFF). The pipeline streams pixel rows, so memory use scales with the row count, not the total pixel count.
Why is my converted ICO file bigger / smaller than I expected?
+
A JPG file with strong compression (e.g. heavily lossy JPG) often grows when re-encoded to a lossless ICO (PNG, TIFF), and a high-bitrate lossless JPG often shrinks dramatically when going to JPG / WebP. The ratio depends on image content (photos compress differently from line art).
Can I use the converted ICO file commercially?
+
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 output.
