JPEG to PNG Conversion FAQ
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. The bitstream is identical to a .jpg: DCT-based lossy compression, usually with 4:2:0 chroma subsampling, wrapped in a JFIF or Exif header. PNG uses DEFLATE compression over filtered scanlines, so every pixel survives exactly, plus a full 8-bit alpha channel.
Can I get transparency once the image is PNG?
+
The PNG format supports it, but the conversion cannot invent it. A JPEG has no alpha channel, so every pixel including the background arrives fully opaque. Run /image-removebackground/ afterwards to cut the subject out — then the alpha channel PNG provides has something to store. PNG is the right choice for screenshots, logos, line art and anything with hard edges or transparency — no ringing, no colour banding.
Does converting JPEG to PNG restore the quality that was lost?
+
No. The compression artefacts already baked into the JPEG are ordinary pixel data now, and PNG preserves them perfectly rather than removing them. The file usually gets larger, sometimes several times larger. It is still worth doing before editing, because further edits will not stack a second generation of loss on top. JPEG shares every JPG limitation — no alpha, generational loss on re-save — with the added nuisance of software that treats the two extensions differently.
Will my CMYK colour survive the conversion to PNG?
+
It is converted to sRGB, because PNG has no CMYK mode. For screen use that is exactly what you want. For commercial print it is not — the gamut shift changes how saturated colours reproduce on press, so send the printer the original JPEG rather than the PNG. PNG is a poor photograph format: a photo saved as PNG is routinely five to ten times larger than the same image as JPG or WebP.
Does the PNG keep the EXIF data from my JPEG?
+
By default yes, wherever the target has somewhere to put it — camera model, exposure settings, lens and GPS coordinates all carry across. GPS is the field worth thinking about: if the image is going to be published, use the strip-metadata option so you are not broadcasting where the photo was taken. JPEG is the same standard as JPG and JFIF — the four-letter extension is the original, and the three-letter one exists only because of the DOS 8.3 filename limit.
Does JPEG to PNG conversion preserve transparency?
+
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. PNG was designed in 1996 as a patent-free replacement for GIF, and became the web’s default lossless image format.
Will my color profile (sRGB / Adobe RGB / CMYK) survive JPEG to PNG?
+
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.
What about EXIF metadata when converting JPEG to PNG?
+
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.
Can I batch-convert many JPEG files to PNG at once?
+
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.
How does JPEG to PNG 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 PNG file have?
+
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.
How small can the PNG get without visible artifacts?
+
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.
