PNG à WebP FAQ sur la conversion

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

Upload your PNG file and the converter applies format-aware quality optimization for WebP. For lossless WebP (PNG, TIFF, BMP) every pixel is preserved; for lossy WebP (JPG, WebP) you can tune the quality factor before download.

Does PNG to WebP conversion preserve transparency?

Transparency survives when WebP 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 WebP instead of WebP=JPG.

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

Embedded ICC color profiles are read from PNG and re-attached to the WebP 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 WebP?

Camera EXIF (ISO, shutter, lens, GPS coords) is preserved by default during PNG → WebP 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 WebP 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 WebP 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 WebP file have?

Default is 1:1 — your WebP 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 WebP get without visible artifacts?

For JPG / WebP, quality 75-85 typically gets the WebP 60-80% smaller than PNG with no visible difference at normal viewing distance. For lossless WebP (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 WebP 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 WebP bigger or smaller than I expected?

A PNG with strong existing compression (lossy JPG) often grows when re-encoded to lossless WebP (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 WebP 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 WebP output.

Les fichiers PNG sont compatibles avec la transparence et utilisent une compression sans perte, ce qui les rend idéales pour les graphiques, les logos et les captures d'écran.
