PNG 에 JPG 변환 FAQ
How do I convert PNG to JPG without losing image quality?
+
Upload your PNG file and the converter applies format-aware quality optimization for JPG. For lossless JPG (PNG, TIFF, BMP) every pixel is preserved; for lossy JPG (JPG, WebP) you can tune the quality factor before download.
Does PNG to JPG conversion preserve transparency?
+
Transparency survives when JPG 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 JPG instead of JPG=JPG.
Will my color profile (sRGB / Adobe RGB / CMYK) survive PNG to JPG?
+
Embedded ICC color profiles are read from PNG and re-attached to the JPG 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.
What about EXIF metadata when converting PNG to JPG?
+
Camera EXIF (ISO, shutter, lens, GPS coords) is preserved by default during PNG → JPG when both formats support metadata. Use the privacy option to strip metadata before download if you need to share images without geolocation.
Can I batch-convert many PNG files to JPG at once?
+
Yes — drag multiple PNG 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.
How does PNG to JPG compare to Photoshop / GIMP for the same task?
+
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.
What resolution will my JPG file have?
+
Default is 1:1 — your JPG keeps the pixel dimensions of the source PNG. If you need to resize as part of the conversion, use /resize-image/ after conversion, or chain it with the /image-resize/ utility.
How small can the JPG get without visible artifacts?
+
For JPG / WebP, quality 75-85 typically gets the JPG 60-80% smaller than PNG with no visible difference at normal viewing distance. For lossless JPG (PNG, TIFF), expect smaller savings — usually 5-30% via better deflate / LZW compression.
Are my PNG files private during conversion?
+
Yes — uploaded PNG 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/.
Does the PNG to JPG converter work for very large images (50MP+)?
+
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.
Why is my converted JPG bigger or smaller than I expected?
+
A PNG with strong existing compression (lossy JPG) often grows when re-encoded to lossless JPG (PNG, TIFF). A lossless PNG 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 JPG commercially?
+
Yes. The conversion is a format change — copyright on the image content stays with you (or whoever held it on the source PNG). We add no watermark, no metadata stamp, and claim no licence over the JPG output.
