PNG to WebP Converter
WebP files are a fraction of the size of PNGs, with transparency intact. Choose lossless (pixel-exact, still around a quarter smaller) or lossy (much smaller, quality you set). Drop a folder of site assets and download a ZIP with the same folder structure and the saving shown for every file. Nothing is uploaded.

File names
Tokens: {name} original name · {n} number ({n:3} zero-padded) · {w} {h} pixels · {date} photo date · the extension is added for you. Example:
Camera details, the date taken and location data are kept when the new format can hold them (JPG, PNG, WebP), exactly as the original had them. Want to see or remove it? Remove EXIF and metadata shows everything a photo carries and strips it losslessly.

About png to webp converter
What this page does differently
- Lossless WebP is a real option (libwebp lossless mode), not just a quality slider, so graphics stay pixel-exact.
- Each result shows the before and after size and the percentage saved, so you can see which files were worth converting.
- Folder structure is kept inside the ZIP, so a converted assets folder drops straight back into a project.
Lossless or lossy?
Lossless for logos, UI graphics and anything you will edit again. Lossy (quality 80 to 90) for photos and large illustrations; it is typically 70 to 90 percent smaller than the PNG.
Does WebP keep transparency?
Yes, in both modes.
Which browsers open WebP?
All current browsers and operating systems since about 2020. Very old software may not; keep the PNGs as a fallback if you must support it.
Limits and privacy
No caps of ours: no file-size limit, no daily count, no account, no watermark, no queue. The only limit is what your device can draw; the line under "Before converting" states it. Files never leave your device: this page makes no network request with your images and keeps working offline once loaded. It reads JPG, PNG, WebP, AVIF, GIF, BMP, ICO and SVG in every browser; HEIC in Safari on iPhone, iPad and Mac. Outputs are JPG, PNG, WebP and multi-size ICO. Free for personal and commercial use; convert only images you own or may modify.
