PNG à JPG FAQ sur la conversion

How do I convert PNG to JPG without losing image quality?

Upload your PNG file, then our converter applies format-aware quality optimization for JPG output. For lossless formats (PNG, TIFF, BMP) we preserve every pixel; for lossy formats (JPG, WebP) you can tune the quality factor before download.

Does PNG to JPG conversion preserve transparency?

Transparency survives when going to PNG, WebP, TIFF, GIF, or SVG. Converting to JPG flattens the alpha channel against a white background — if you need transparency, target a transparency-aware format instead of JPG.

Will my color profile (sRGB / Adobe RGB / CMYK) survive PNG to JPG?

Embedded ICC color profiles are read from the source 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.

What about EXIF metadata when converting PNG to JPG?

Camera EXIF (ISO, shutter, lens, GPS) is preserved by default during PNG → JPG conversion when both formats support metadata. Use the privacy option to strip metadata before download if you want to share images without geolocation.

Can I batch-convert hundreds of PNG files to JPG at once?

Yes — drag multiple PNG files into the upload zone and we queue them in parallel. Free users get 100MB 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 straightforward format conversion we run the same libpng / libjpeg-turbo / libwebp / ImageMagick pipelines a desktop editor uses, with the same quality. The difference is that desktop tools open one file at a time; we accept a batch and run them in parallel.

What resolution and dimensions will my JPG file have?

Default behaviour is 1:1 — your JPG output has the same pixel dimensions as the source PNG. Use a separate /resize-image/ step after conversion if you need to downscale or upscale as part of the workflow.

How small can the JPG file get without visible artifacts?

For JPG / WebP, quality 75-85 typically gets the file 60-80% smaller than the source PNG with no visible difference at normal viewing distance. For lossless targets (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, or share the pixel data. The full privacy policy and retention window are documented at /privacy/.

Does the PNG to JPG converter work for very large images (50MP+)?

Yes for free up to 100MB. Premium handles larger inputs (300MB+) and exotic per-pixel depths (16-bit PNG, 32-bit float TIFF). The pipeline streams pixel rows, so memory use scales with the row count, not the total pixel count.

Why is my converted JPG file bigger / smaller than I expected?

A PNG file with strong compression (e.g. heavily lossy JPG) often grows when re-encoded to a lossless JPG (PNG, TIFF), and a high-bitrate 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 file 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 output.

PNG

Les fichiers PNG comprennent la transparence et l'utilisation de compression sans perte, ce qui les rend idéales pour les graphiques, logos et captures d'écran.

JPG

Les fichiers JPG utilisent une compression perdue optimisée pour les photographies, fournissant de petites tailles de fichiers tout en assurant la qualité visuelle.
