JPEG to PNG Conversion FAQ

How do I convert JPEG to PNG without losing image quality?
+
Upload your JPEG file and our converter applies format-aware quality optimization for PNG output. For lossless targets (PNG, TIFF, BMP) every pixel is preserved bit-for-bit; for lossy targets (JPG, WebP) you can tune the quality factor (default 90) 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.
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.
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.
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.
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.
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, pick a transparency-aware target instead of PNG. PNG was designed in 1996 as a patent-free replacement for GIF, and became the web’s default lossless image format.
Embedded ICC colour profiles are read from the source 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 with a soft-proof step.
Camera EXIF (ISO, shutter, lens, GPS) is preserved by default during JPEG -> PNG when both formats support metadata. Use the privacy toggle to strip metadata before download if you want to share images without geolocation or device-fingerprint exposure.
Yes — drag multiple JPEG files into the upload zone and they queue in parallel. Free tier accepts 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 straightforward format conversion we run the same libpng / libjpeg-turbo / libwebp / ImageMagick pipelines a desktop editor uses, at the same quality. The difference is that desktop tools open one file at a time; we accept a batch and run them in parallel on server-side workers.
Default behaviour is 1:1 — your PNG output has the same pixel dimensions as the source JPEG. If you need to resize as part of the conversion, use /resize-image/ after, or chain the operations with the /image-pipeline/ utility.
For JPG / WebP, quality 75-85 typically yields a PNG 60-80% smaller than the 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 than the source already had.

JPEG

JPEG uses lossy compression optimized for photographs, balancing standard and file size.

PNG

PNG files process transparency and use lossless compression, making them ideal for graphics, logos, and screenshots.
