You have a PNG and need a JPG. Or a WebP you can't open in an old application. Or a GIF you want as a static image. Converting between image formats is something you do constantly, and you shouldn't need to install software or upload to a sketchy converter site to do it.
The Image Converter at Ultimate Tools converts between image formats in your browser — no upload, no account, instant download.
How to Convert an Image
- Open the Image Converter
- Drop your image onto the upload area
- Select the output format
- Adjust quality (for JPEG/WebP outputs)
- Click Convert and download
The converted file downloads immediately.
Supported Conversions
| From | To |
|---|---|
| JPG | PNG, WebP, GIF |
| PNG | JPG, WebP, GIF |
| WebP | JPG, PNG, GIF |
| GIF | JPG, PNG, WebP |
| BMP | JPG, PNG, WebP |
Which Format Should You Use?
| Format | Best For | File Size |
|---|---|---|
| JPG | Photos, anything with gradients | Small |
| PNG | Screenshots, logos, images needing transparency | Larger |
| WebP | Web images — combines JPEG quality with PNG transparency support | Smallest |
| GIF | Simple animations (static conversion loses animation) | Varies |
Quick guide:
- Website images where you control the format → WebP
- Image with a transparent background → PNG
- Photograph to send over email or chat → JPG
- App/tool that doesn't support WebP → JPG or PNG
The Quality Slider
For JPG and WebP outputs, a quality slider controls the compression:
- 100% — maximum quality, largest file size
- 80% (default) — excellent quality, ~40–60% smaller than 100%
- 60% — noticeably compressed, fine for web thumbnails
- 40% or less — visible artifacts, only use for very aggressive size reduction
PNG output has no quality slider — PNG is lossless, so all PNG exports are the same quality.
Common Use Cases
Converting WebP for old software: WebP is widely supported in browsers but older desktop apps (Photoshop pre-2022, some Windows viewers) can't open WebP. Convert to JPG or PNG for compatibility.
Making a logo transparent: You have a JPG logo on a white background. Convert to PNG, then remove the white in an image editor — PNG supports transparency, JPG doesn't.
Reducing size before uploading: Convert a large PNG to WebP or JPEG to cut the file size before attaching to an email or uploading to a site with file size limits.
Preparing images for web: Browsers support WebP and it's significantly smaller than JPEG or PNG for similar quality. Convert your image assets before deploying.
Getting a static frame from a GIF: Convert a GIF to JPG/PNG to extract the first frame as a static image.
Privacy
The conversion runs entirely in your browser using the Canvas API. Your image is decoded in memory, re-encoded in the target format, and downloaded directly — it never touches a server.
