Supports: WEBP
WebP is Google's web image format, released in 2010. It supports both lossy and lossless compression plus an 8-bit alpha channel and animation, and on photographs it routinely produces files 25–35% smaller than JPEG at comparable visual quality. The catch in 2026 is reach: while every modern browser handles WebP, plenty of editors, document tools, marketplaces, and OS-level previews still treat it as a second-class format. PNG, standardised as RFC 2083 in 1997, opens in essentially every image-aware program written since. Converting WebP → PNG trades smaller bytes for universal compatibility.
| Property | WebP | PNG |
|---|---|---|
| Released | 2010 (Google) | 1996; RFC 2083 in 1997 |
| Compression | Lossy or lossless (chosen at encode time) | Always lossless (DEFLATE) |
| Typical size for photos | ~25–35% smaller than JPEG | 3–5× the WebP for photos |
| Transparency | 8-bit alpha (lossy or lossless WebP) | 8-bit alpha (RGBA) |
| Animation | Yes (animated WebP) | No (use APNG or GIF) |
| Color depth | 8-bit per channel | 1, 2, 4, 8, 16-bit; palette indexed |
| Browser support | Chrome, Firefox, Edge, Safari 16+, Opera (~96%) | Universal since 1996 |
| Editor support | Photoshop 23.2+, modern GIMP, Affinity | Universal — every editor reads PNG |
| Best for | Web delivery, modern apps | Editing, design assets, universal sharing |
| Setting | Default | Lower values | Higher values |
|---|---|---|---|
| Compression level (1–9) | 6 | Faster encode, larger PNG | Slower encode, smaller PNG |
| Compression speed (1–9) | 4 | More CPU, marginally smaller | Less CPU, marginally larger |
| Color palette | ORIGINAL | 2–256 indexed colors shrink graphics 5–20× | (n/a — ORIGINAL is the max) |
| Quality Preset | Very High | Lower preset trims pre-encode detail | Highest preserves source pixels |
For photographs from a lossy WebP source, leave palette on ORIGINAL — indexed color will posterize gradients. For logos, icons, screenshots of UI, and flat illustrations, drop to 16, 32, or 64 colors with dithering to cut PNG size dramatically without visible loss.
No. If the source WebP was lossy-encoded, the JPEG-style artifacts (blocking around edges, smoothing in flat areas) are already baked into the decoded pixels and survive the conversion to PNG. The PNG is a lossless copy of whatever the WebP decoded to. The real benefit is preventing future quality loss — every subsequent edit and re-save stays lossless — plus universal editor / tool compatibility.
Almost certainly yes, especially for photos: a 200 KB photographic WebP routinely becomes a 700 KB – 1.5 MB PNG. WebP's lossy mode (VP8 / VP8L) is more efficient than PNG's DEFLATE for natural images. For limited-color graphics, screenshots of UI, and icons, PNG with an indexed palette can sometimes match or beat the WebP, so use the Colors → By Color Reduction + Dither option when shrinking graphics.
Yes. WebP supports an 8-bit alpha channel and PNG stores RGBA natively, so the conversion preserves alpha exactly — logos, icons, and UI elements with transparent backgrounds stay transparent. One edge case: WebP files saved with "lossy alpha" sometimes confuse older Photoshop versions; converting through this tool decodes the alpha cleanly before writing the PNG, which is why people use WebP → PNG to "fix" transparency that imports oddly into Photoshop CS6 or CC 2021.
Native WebP support arrived in Photoshop 23.2 (February 2022). Installations stuck on older builds, or anything older than CC 2022, need the WebPShop plugin from Google or a conversion to PNG first. If a colleague exported WebP from a current Photoshop and you can't open it on CS6, the fastest fix is PNG.
XConvert's WebP-to-PNG flow extracts the first frame as a still PNG by default — useful for thumbnails and previews. If you need the whole animation preserved, WebP to GIF keeps every frame with universal tool support; animated PNG (APNG) is technically lossless but is much less widely accepted by editors and embed targets.
Yes — drop in entire folders of WebP downloads. Each file converts in parallel on our servers and downloads individually or as a single ZIP. Settings (Quality Preset, Compression level, Colors, resolution) apply uniformly to the batch.
Modern sites serve WebP to browsers that advertise support in the Accept header because the smaller payload speeds up page loads. Your browser caches and "save image as" writes the served WebP, not the original JPEG or PNG behind it on the server. Converting after saving recovers a universally-usable format for slides, edits, and uploads.
The current tool focuses on pixel dimensions and compression — set width × height or use a Preset Resolution for output sizing. If you specifically need a stamped DPI tag for a print workflow, Resize PNG or Compress PNG expose explicit DPI controls (72 / 96 for screen, 150 for draft prints, 300 for offset print, 600+ for fine-art).
Yes — PNG to WebP does the reverse direction, useful when you're shipping the final image to a website where smaller bytes matter. The round-trip WebP → PNG → WebP is safe if the second WebP is encoded lossless; encoding lossy on the second hop recompresses everything.
