About PNG and WEBP
PNG .png
A lossless image format built for graphics rather than photographs. Every pixel it stores comes back exactly as it went in, and it carries a full alpha channel for transparency.
Good for
- Lossless — no generation loss no matter how often you re-save
- Full 8-bit alpha, so edges blend cleanly over any background
- Sharp on text, screenshots, logos and line art
Trade-offs
- Much larger than JPEG for photographs
- No animation in the baseline format
- Large photographic PNGs are slow to transfer
image/png
WebP .webp
Google's image format, designed to replace both JPEG and PNG. It can compress either way — lossy for photographs, lossless for graphics — and supports transparency and animation in both modes.
Good for
- Typically 25–35% smaller than JPEG at comparable quality
- Transparency in lossy mode, which JPEG cannot do at all
- One format covers photographs, graphics and short animations
Trade-offs
- Older software and some print workflows still will not open it
- Lossy WebP discards detail just as JPEG does
- Editing tools support it less consistently than PNG or JPEG

PNG and WEBP side by side
| PNG | WEBP | |
|---|---|---|
| Compression | Lossless | Lossy or lossless |
| Transparency | Yes — 8-bit alpha | Yes |
| Animation | No | Yes |
| Typically used for | Screenshots, logos, UI assets, anything with transparency | Web images where size matters |
What changes when you convert PNG to WEBP
You choose how much to keep
WEBP can compress either lossily or losslessly, so the quality setting decides the outcome rather than the format. High quality stays close to the PNG you started with; lower settings trade visible detail for a much smaller file.
Camera data is removed by default
A PNG straight from a phone or camera carries EXIF metadata — model, settings, timestamp and, quite often, the GPS coordinates of where the photo was taken. The converted WEBP is written without it, so a file you are about to share does not quietly carry your location. The orientation flag is read and applied to the pixels first, so the image will not come out sideways once the tag holding it is gone. If you need the metadata kept, there is a setting for it.
How the WEBP is written
Our default is quality 82, with the encoder choosing colour subsampling per image rather than applying it blindly. The quality control on the converter moves this if you need to — the default aims to be indistinguishable from the source at a sensible file size, rather than to win a compression benchmark.

Why your PNG is so much bigger than your JPEG
The same photograph can be 300 KB as a JPEG and 4 MB as a PNG. Here is what each format is actually doing, and how to tell which one your file wants to be.

Where your transparent background went
Transparency is the property most often lost silently in a conversion — the file looks perfect until it lands on a coloured background and grows a white rectangle.
