About this tool
The tool decodes the image with your browser, redraws it on a canvas at the size you choose and re-encodes it. WebP usually produces the smallest file for the same visual quality; JPEG is the safest choice for old software; PNG is lossless and keeps transparency.
Quality only applies to JPEG and WebP. A value between 70 and 85 is invisible to most people and typically cuts the file size by half or more. Setting a maximum width scales the image down proportionally, which is often the biggest saving of all.
Frequently asked questions
- Are my images uploaded anywhere?
- No. The conversion happens entirely in your browser using the Canvas API. The page works even with the network disconnected.
- Which format should I choose?
- WebP for the web, JPEG for photos that must open everywhere, PNG for screenshots, logos and anything that needs transparency.
- Why is my PNG larger than the original?
- PNG is lossless, so re-encoding a compressed JPEG as PNG cannot shrink it. Choose WebP or JPEG and lower the quality instead.
- Does it keep EXIF data?
- No. Redrawing on a canvas strips metadata such as location and camera model, which is usually what you want before sharing.
- Can I convert HEIC or AVIF files?
- Only if your browser can display them. Safari opens HEIC; most current browsers open AVIF. The output is always JPEG, PNG or WebP.
