JPG 에 ICO 변환 FAQ
How do I convert a JPG image to ICO?
+
Drop your JPG image into the upload area. PDF.to re-encodes the pixels into the ICO container and gives you the new file in seconds. No account is needed.
Will the JPG to ICO conversion lose detail or sharpness?
+
If ICO is a lossless format (PNG, BMP, TIFF), pixel data is preserved exactly. If ICO is lossy (JPG, WebP, JPEG), we use a high default quality setting that is visually indistinguishable from the source for almost all images.
Does the JPG to ICO converter keep transparency?
+
When ICO supports an alpha channel (PNG, WebP, GIF) and the original JPG had transparency, we keep it. Converting to a format without transparency (JPG, BMP) fills transparent areas with white by default.
Does it preserve EXIF, color profile, and DPI from my JPG file?
+
ICC color profiles and DPI tags are preserved when ICO supports them. EXIF metadata (camera, GPS, timestamps) is stripped by default for privacy; turn it on in PRO if you need it.
Can I convert a vector JPG to a raster ICO (or vice versa)?
+
벡터에서 래스터로 변환은 합리적인 기본 해상도(일반적으로 2배 디스플레이)로 래스터화합니다. 옵션 패널에서 DPI를 재정의할 수 있습니다. 래스터에서 벡터로 변환은 최선의 노력 트레이싱이며 사진이 아닌 로고 및 선 아트에서 가장 잘 작동합니다.
What is the largest JPG image I can convert to ICO?
+
Free accounts allow images up to the free size limit. PRO accounts allow much larger images and up to 1 gigapixel per image, which covers large scans and panoramas.
Can I batch-convert JPG images to ICO?
+
Yes — drag a folder of JPG files onto the page. Each is converted independently and zipped into a single download when done.
Will the converted ICO have the same dimensions as my JPG?
+
Yes — pixel dimensions are preserved by default. If you want to resize during conversion, use the ICO resize tool after the conversion finishes.
Is my JPG image private when I convert it?
+
Yes. Uploads are encrypted in transit, the conversion job runs on an isolated worker, and the original JPG plus the resulting ICO are deleted within an hour.
Why is my converted ICO file larger than the original JPG?
+
If ICO is lossless and JPG was lossy (or vice versa), file size will change. PNG (lossless) is typically larger than JPG (lossy) for photographs but smaller for solid-color graphics and screenshots.
Does the JPG to ICO converter handle animated images?
+
If JPG is animated (GIF, WebP, APNG) and ICO also supports animation (GIF, WebP), all frames are preserved. Converting animated JPG to a static target (JPG, PNG) keeps only the first frame.
Can I convert JPG to ICO on my phone?
+
Yes. The converter is mobile-responsive and processes images server-side, so you can convert JPG to ICO from any iPhone or Android device without using local storage.
