Add your CUR file
Drop one or more .cur files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
CUR to WEBP
Converting a .cur image to .webp re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.

Converting a .cur image to .webp re-encodes the pixels for a different balance of size, quality, and support. A .cur file is a Windows cursor: a container holding one or more pointer images at different sizes, plus a hotspot — the exact pixel within the image that counts as the click point. It shares its structure with the Windows icon format and differs from it in only two fields.
A .webp file is Google's web-oriented image format, offering both lossy and lossless compression plus alpha and animation in one container. At equivalent visual quality, .webp files typically undercut JPEG by 25-35 percent, which is why CDNs and site optimizers convert to it aggressively. For this route the practical draw is smaller than JPEG for photos and usually smaller than PNG for graphics and one format covers lossy, lossless, alpha, and animation — balanced against mandatory 4:2:0 subsampling in lossy mode caps color fidelity below high-quality JPEG or AVIF, which is worth knowing before you commit a large batch.
Why convert CUR to WEBP?
The practical trigger for this conversion is usually a mismatch: with .cur, windows-specific; macOS and Linux use entirely different cursor mechanisms. Switching to .webp buys you smaller than JPEG for photos and usually smaller than PNG for graphics, which is why it is the better fit for serving photos and graphics on websites where bandwidth and Core Web Vitals matter. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
CUR vs WEBP at a glance
| Aspect | Windows cursor (.cur) | WebP image (.webp) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Lossy — discards detail it judges invisible to shrink files |
| How it stores data | the directory header is identical to ICO except that the type field at offset 2 is 2 rather than 1 — that single value is what makes a file a cursor instead of an icon | lossy mode encodes VP8 intra frames with block prediction; lossless mode uses its own dedicated coding with spatial predictors and color transforms |
| Strongest at | extracting a cursor image for documentation, screenshot annotation or design reference | serving photos and graphics on websites where bandwidth and Core Web Vitals matter |
| Weak spot | windows-specific; macOS and Linux use entirely different cursor mechanisms | mandatory 4:2:0 subsampling in lossy mode caps color fidelity below high-quality JPEG or AVIF |
| Metadata | the hotspot coordinates and the per-entry size table belong to the container rather than to the image, and no raster target has anywhere to record them. The embedded PNG frame's own metadata is carried through the conversion | eXIF and XMP travel in dedicated RIFF chunks and ICC profiles are supported, though a fair amount of conversion software strips metadata by default when writing WebP |
Pick WEBP as the output
Select .webp in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if WEBP is selectable, the route is real and validated.
Convert on your device
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid WEBP file. Outputs keep the original filename with the .webp extension.
CUR to WEBP questions, answered
Will converting CUR to WEBP lose quality?
Some. Since cur is lossless-oriented and webp is lossy-oriented, the encoder will discard detail it judges least visible; the quality slider controls how aggressive that is. Keep the original .cur if you may need a pristine master later.
Is it private to convert CUR files here?
Yes — the .cur file is processed inside your browser tab and never uploaded. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders. Close the tab and the file is gone from memory.
Where will the WEBP file work?
Chrome, Edge, Firefox, and Safari (since version 14 in 2020) all decode WebP natively, as do Android and current versions of Windows and macOS system viewers. Older tools from before roughly 2020 — legacy Photoshop releases, older email clients, many kiosk printers — commonly fail on it, so JPEG or PNG remains the safer handoff format outside the browser.
Will the WEBP file be bigger or smaller than my CUR?
Smaller, usually dramatically so — that is the main reason this route exists. The quality slider trades size against fidelity; the default sits at the point where most people cannot spot the difference.
What happens to the metadata in my CUR file?
In .cur, the hotspot coordinates and the per-entry size table belong to the container rather than to the image, and no raster target has anywhere to record them. The embedded PNG frame's own metadata is carried through the conversion. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
