PNG to WebP Converter In your browser, nothing uploaded
EXIF metadata is removed. Decoding and redrawing the image carries no GPS coordinates, camera model or timestamp across, so the file you download has none of it. If you need that data kept, copy the originals instead.

How to Convert PNG to WebP
- Drag and drop your PNG files into the converter above, or click to browse.
- The converter automatically outputs WEBP format. Adjust quality if needed.
- Click download to save your converted WEBP files. For multiple files, use "Download All as ZIP."
What is WEBP?
WebP came out of Google in 2010, built on the prediction machinery of the VP8 video codec and later given a separate lossless mode of its own. It handles transparency, animation, and both kinds of compression, which is why it ended up replacing three older formats at once on most websites. Every current browser decodes it. The conversion here runs in lossy mode at a quality you control, with the slider starting at 85, so the encoder is free to discard the detail it judges you will not miss. That is where the size saving comes from, and it is a bigger saving than anything PNG can offer, because PNG is not allowed to discard anything at all.
What is a PNG File?
PNG (Portable Network Graphics) is a lossless image format widely used for graphics, screenshots, and images that require transparency. PNG files are typically larger than JPEG or WebP because they preserve every pixel without compression artifacts, making them ideal for graphics but less efficient for photographs.
PNG vs WEBP
PNG's honesty is also its weakness on the web. It stores every pixel exactly, which is precisely what you want for a logo you will edit again next month and precisely what you do not want for a 3000-pixel-wide photograph sitting in a hero banner. WebP at quality 85 will typically take that photograph down by two thirds or more with nothing visible at normal viewing distance. Where the calculation changes is content with hard edges. Screenshots, charts, UI mockups and anything containing small text are exactly the material lossy compression struggles with — at 85 you can sometimes see letters go slightly mushy. Push the slider to 95 for those and the file is still smaller than the PNG. Keep the PNG as your master copy regardless. This conversion is for the copy you publish, not the one you keep.
Why Convert PNG to WebP?
- A 2.4 MB PNG photograph commonly lands near 300 KB at the default quality — the difference between a hero image that appears at once and one that does not.
- Transparent PNGs are usually the heaviest things on a page. WebP keeps the alpha channel and cuts them to a fraction of the size.
- Largest Contentful Paint is measured against the biggest image above the fold. Often that is the one PNG nobody got round to converting.
- Every megabyte you do not serve is one a CDN does not bill you for.
Frequently Asked Questions
Does WebP keep transparency the way PNG does?
Yes, and this is the main reason it can replace PNG for web graphics rather than sitting alongside it. WebP carries a full alpha channel, so semi-transparent edges and drop shadows come across properly rather than acquiring a halo. A transparent WebP is normally far smaller than the transparent PNG it replaced.
How much smaller will the files actually be?
For photographic content, expect roughly 60 to 80 percent off at the default quality. For flat graphics and icons the gap narrows a lot, because PNG is already very good at long runs of identical colour, and the saving might be closer to a third. The only reliable way to know is to convert the file and compare, which takes a couple of seconds here.
Will screenshots and text stay sharp?
Not entirely, at the default setting. Quality 85 is tuned for photographs, and lossy compression of any kind is at its weakest around the hard black-on-white edges that make up text. If the image is a screenshot, a diagram or a chart, raise the slider to 95 before converting. If the text has to be pin-sharp, keep the PNG. It is the honest answer even though it means not using this page.
Do I still need a PNG fallback for older browsers?
Not for browsers. WebP has been decoded natively by every major one for years now, and the holdouts that could not are no longer a measurable share of anybody's traffic. The gap is elsewhere: some email clients render WebP badly or not at all, and a good deal of desktop software still cannot open one. Keep PNG or JPG for anything you attach to an email.
