CUR to WebP Converter
Processing entirely on your device — large files may take a moment.
WebP is the go-to format for fast websites: smaller files mean quicker pages, lower bandwidth and better SEO scores. If your files are still in CUR format, this page is the shortcut: CUR is the Windows cursor format — structurally an ICO file with a hotspot, holding small bitmap cursor images.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How CUR compares to WebP
| CUR | WebP | |
|---|---|---|
| Compression | BMP/PNG members (as ICO) | Lossy and lossless modes |
| Transparency | Supported | Supported (alpha) |
| Animation | No (that is .ani) | Supported |
| Metadata | Hotspot coordinates | EXIF, ICC embeddable |
| Best for | Windows cursors and UI assets | Web images and bandwidth savings |

About the CUR format
CUR is the Windows cursor file: structurally identical to ICO (several small bitmap sizes bundled), with the addition of a hotspot coordinate that marks which pixel is the pointer's tip. Windows ships most of its system cursors as CUR files.
Designers customizing cursors or extracting UI assets meet CUR files that no modern image tool opens. Converting to PNG (the largest embedded size) makes them editable, viewable and reusable in web apps that implement custom cursors.
+ Strengths
- ✓Windows cursor standard
- ✓Multiple sizes in one file
- ✓Hotspot data travels with the image
! Limitations
- −Tiny sizes only (usually ≤48px)
- −Meaningless outside cursor use
About the WebP format
WebP is Google's image format, released in 2010 and built on the VP8 video codec. In lossy mode it typically produces files 25–35% smaller than JPG at the same visual quality, and it also has a true lossless mode that beats PNG. Crucially, one format covers what used to require two: lossy photos with transparency, and even animation, all in a single container.
Browser support is no longer the barrier it once was: Safari added WebP in iOS 14 (2020), and every modern browser now decodes it. The remaining friction is with older desktop software and a hard dimension limit of 16383×16383 pixels, which rules out very large panoramas and print masters.
+ Strengths
- ✓25–35% smaller than JPG at equal visual quality
- ✓Transparency and animation built into the same format
- ✓Supported by every current browser and most CDNs
- ✓Has a genuine lossless mode that out-compresses PNG
! Limitations
- −Hard limit of 16383×16383 pixels per image
- −Older photo apps and OS image viewers may not open it
- −Encoding is more CPU-intensive than JPG
Why convert CUR to WebP?
Converting makes sense where the strengths of WebP meet what CUR cannot give you. 25–35% smaller than JPG at equal visual quality Meanwhile Tiny sizes only (usually ≤48px) One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this CUR to WebP converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will converting CUR to WebP reduce quality?
WebP uses lossy compression, so a small amount of recompression is unavoidable. The quality slider lets you choose between maximum fidelity and smallest file size — the default is visually indistinguishable for photos.
Can I convert several CUR files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your CUR files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
