How do I convert JPEG to PNG without losing image quality?
+
Upload your JPEG file and the converter applies format-aware quality optimization for PNG. For lossless PNG (PNG, TIFF, BMP) every pixel is preserved; for lossy PNG (JPG, WebP) you can tune the quality factor before download.
Transparency survives when PNG 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 PNG instead of PNG=JPG.
Embedded ICC color profiles are read from JPEG and re-attached to the PNG 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 JPEG → PNG 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 JPEG 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 PNG keeps the pixel dimensions of the source JPEG. 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 PNG 60-80% smaller than JPEG with no visible difference at normal viewing distance. For lossless PNG (PNG, TIFF), expect smaller savings — usually 5-30% via better deflate / LZW compression.
Yes — uploaded JPEG 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 JPEG with strong existing compression (lossy JPG) often grows when re-encoded to lossless PNG (PNG, TIFF). A lossless JPEG 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 JPEG). We add no watermark, no metadata stamp, and claim no licence over the PNG output.

JPEG

Format JPEG wykorzystuje stratną kompresję zoptymalizowaną pod kątem fotografii, co zapewnia równowagę między jakością i rozmiarem pliku.

PNG

Pliki PNG są kompatybilne z przejrzystością i użyciem kompresji bez strat, co sprawia, że są idealne dla grafiki, logo i zrzutów ekranu.
