How to convert an image
- Choose or drop your images. You can convert many files in one go.
- Pick the target format — JPG, PNG or WebP.
- Set the quality for JPG or WebP (PNG is always lossless).
- Download the converted files. Dimensions stay the same; the list shows each file's size before and after.
Typical conversions: WebP to JPG when a program or upload form doesn't accept WebP, PNG to JPG to make a large photo smaller, JPG to PNG when an editor or print shop asks for PNG, and JPG or PNG to WebP to make a website faster.
JPG, PNG or WebP?
| Format | Compression | Transparency | Best for |
|---|---|---|---|
| JPG (JPEG) | Lossy | No | Photos; maximum compatibility with every device and program |
| PNG | Lossless | Yes | Screenshots, logos, text, graphics with sharp edges |
| WebP | Lossy or lossless | Yes | Websites — smaller files at the same visual quality |
Google's comparison found WebP lossy images 25–34% smaller than JPG at the same visual quality, and lossless WebP about 26% smaller than PNG. All current browsers show WebP, which is why many sites now serve it — and why downloaded images sometimes arrive as .webp files that older software won't open. Converting them to JPG solves that.
What changes when you convert
- To JPG: JPG has no transparency, so transparent areas (for example around a logo) become white. Each save at less than 100% loses a little detail, so convert from the best copy you have.
- To PNG: nothing more is lost, but a photo saved as PNG is usually several times larger than the JPG — PNG suits graphics better than photos.
- To WebP: usually the smallest result. Chrome, Edge and Firefox can create WebP files; if your browser can't, the tool tells you instead of producing the wrong format.
- Metadata: the converted image is freshly drawn, so EXIF data such as the camera model and GPS location is not carried over. Colors are saved in standard sRGB.
Other input formats
The converter opens anything your browser can display: JPG, PNG, WebP, GIF (the first frame), BMP and ICO in every modern browser, AVIF in current Chrome, Edge, Firefox and Safari, and HEIC/HEIF photos from iPhones in Safari. If a file can't be opened, it is listed by name so you know which one to convert another way.
Private and offline
Unlike most converters, this one never uploads your files: the decoding and encoding happen in your browser on your own device. That keeps personal photos private and makes the conversion fast even on a slow connection. To make the result smaller as well, use the image compressor; to change the dimensions, the image resizer; and to combine images into one document, JPG to PDF.
Frequently asked questions
How do I convert WebP to JPG?
Choose or drop the WebP files, select JPG as the target format and download the results. The dimensions stay the same, and transparent areas become white.
Is PNG or JPG better?
JPG is better for photos because the files are much smaller. PNG is better for screenshots, logos and anything with text, sharp edges or transparency, because it never loses detail.
Will converting reduce quality?
Converting to PNG never loses quality. Converting to JPG or WebP below 100% discards a little detail; at 90–95% the difference is not visible in normal viewing.
Are my images uploaded?
No. The conversion happens entirely in your browser and nothing is sent to a server.
Can I convert HEIC iPhone photos?
Yes in Safari, which can open HEIC images. Other browsers can’t read HEIC; there, set your iPhone camera to “Most Compatible” to take JPG photos, or share the photos as JPG.
