About WebP Converter
Converts an image to or from the WebP format — a modern image format that typically produces smaller file sizes than JPG or PNG at similar visual quality, widely used for faster-loading websites. Drop a JPG or PNG to convert it into WebP with adjustable quality, or drop an existing WebP file to convert it back out to JPG or PNG. Under "More options" you can also resize it, turn or flip it, make it black and white, and keep or remove camera and location details.
Upload your image. If it's a JPG or PNG, adjust the quality and convert to WebP. If it's already a WebP file, pick JPG or PNG as the output format instead. Open "More options" if you also want to change the size or colour. Download the result either way.
If you're preparing images for a website, WebP is usually the better choice for page-load speed, but keep a JPG or PNG backup if you need broad compatibility with very old software. Converting a WebP with transparency to JPG will lose that transparency, since JPG doesn't support it — PNG keeps it.
Watch: WebP Converter in Action
- Should I use WebP for a website I'm building?
- Usually yes, if page-load speed matters — WebP typically produces smaller files than JPG or PNG at similar visual quality. Keep a JPG or PNG backup if you need compatibility with very old software or specific legacy requirements.
- Can this tool convert WebP back to JPG or PNG?
- Yes — drop an existing WebP file and the tool automatically detects it, offering JPG or PNG as the output format instead of WebP. JPG has its own quality slider, starting at 92%.
- What's the difference between this and Convert Image?
- This tool is focused specifically on WebP — converting into it with a dedicated quality slider, or out of it to JPG/PNG. Convert Image handles conversion between PNG, JPEG, WebP, AVIF, GIF, BMP, ICO and TIFF in either direction, with a format picker and a quality slider for the lossy formats. If WebP is always one side of your conversion, this dedicated tool is quicker; for any other conversion, Convert Image is the right tool.
- What does the quality slider actually control?
- How much WebP's lossy compression simplifies the image when converting INTO WebP — higher values keep more detail at a larger file size, lower values compress harder at the cost of visible quality loss. 80% is a common, well-balanced default for most photos. When converting a WebP back out to JPG the same slider sets the JPG quality (starting at 92%); PNG is lossless, so it has no quality setting.
- Is WebP conversion always smaller than the original?
- Usually, but not guaranteed — a small or already-heavily-compressed source image can occasionally end up similar in size or slightly larger after WebP conversion, especially at a high quality setting. Check the reported result size before assuming it's always smaller.
- Will transparency be preserved either direction?
- Converting into WebP or into PNG both preserve transparency. Converting a transparent WebP into JPG loses it, since JPG has no transparency support at all — choose PNG instead if the source has transparency you want to keep.
- Are my images uploaded to a server?
- No — conversion in either direction runs entirely in your browser using the canvas element. Your image never leaves your device.
- What image formats can I convert into WebP?
- Any standard format your browser can display as an image — JPG and PNG are the most common, but any browser-renderable image source works as input.
- Will converting to WebP make my image smaller?
- Often, but not always. The confirmation message shows the new size in KB, so compare it with the size in the file bar. A lower quality value usually saves more, at the cost of visible artifacts.
- Can I convert a WebP file back to JPG or PNG?
- Yes. Drop the WebP file and choose JPG or PNG under Convert to. JPG is selected first, and the output is saved with your original name and the new extension.
- What happens to transparent areas?
- Transparency is kept when converting a PNG to WebP. When a WebP becomes a JPG, transparent areas are filled with a colour because JPG has no transparency; white is the starting colour and you can change it. Choose PNG to keep it.
- Can I resize or change the picture while converting?
- Yes. Open More options to set a width and height (with the same five fit modes as Convert Image), rotate or mirror the picture, make it black and white, and keep or remove camera and location details. Details can be kept only when both the original and the result are JPG. If your browser cannot write WebP, the tool says so instead of producing a wrong file.
- Does it open formats like HEIC or TIFF?
- The loader can read iPhone HEIC, TIFF and, where your browser supports it, AVIF, as well as common web formats, and then writes WebP. A file it cannot decode shows an error message naming the file.
How to use WebP Converter
Drop an image. What you see next depends on the file. For a JPG, PNG or other ordinary picture, a Quality slider appears, running from 10 to 100 percent and starting at 80. Open More options if you also want to set a width and height with a fit mode, turn or mirror the picture, make it black and white, or keep its camera details. Press Convert to WebP, check the size shown in the confirmation and the preview, then use the Download WebP button.
For a file that is already WebP, a Convert to choice between JPG and PNG appears, with JPG selected first (it has its own quality slider starting at 92 percent; PNG has none). Press the matching convert button and download the .jpg or .png. In both directions the result keeps your original file name with the new extension. New takes you back to the start, and changing the JPG or PNG choice clears any earlier result so you cannot download the wrong format by accident.
When to use it
Choose it when a website builder, page-speed report or content system asks for WebP, when you want a lighter copy of a large JPG or PNG for a web page, or when a WebP saved from the internet will not open in an editor, a form or a document that accepts only JPG or PNG. It handles one image at a time, which suits a quick one-off job.
When not to use it
Skip it for converting many images in one go, where the bulk image tool saves effort, and for pictures headed to old software or email programs that cannot show WebP. Do not use the slider to hit a specific number of kilobytes, since it sets encoder quality rather than file size. For general conversions between JPG, PNG and other formats, the Convert Image tool is the better fit.
Tips for best results
A lower slider value gives a smaller file, but faces, gradients and sharp text show artifacts first, so step down in tens and compare the sizes reported. A transparent PNG logo keeps its see-through areas when it becomes WebP. Going from WebP to JPG fills transparent areas with a colour (white to begin with, changeable), which suits a white page, while choosing PNG keeps transparency. Camera and location details are removed unless you tick the keep option, which works only when both the original and the result are JPG.
Limitations
The converter relies on your browser's own image encoder, so a browser that cannot write WebP cannot produce one here. The result is a single still picture, so animated GIFs or animated WebP files lose their motion. A converted copy is a re-encoding of the pixels, not a bit-for-bit duplicate, so keep your original whenever the exact pixels matter.
Privacy
Both directions run inside your browser tab: the image is drawn onto a canvas, re-encoded by the browser itself and offered as a download. No file is sent anywhere, and nothing extra has to be fetched for this conversion. The size quoted in the success message is measured on your device from the newly created file.
