Drop an image, video, audio, document, PDF, spreadsheet or archive. Pick your output format. Get the converted file instantly — without sending a single byte to a server.
Every conversion — images, video, audio, documents — runs locally in your browser. No upload, no account, no server involved.
I can now send iPhone HEIC shots to clients without fighting with iCloud exports. Drag in, pick WebP, download.
Converted 200 PNGs to AVIF lossless for our design system. The ICC color profile came through perfectly — every swatch matched exactly.
We switched our image pipeline to WebP. kindatool was the only browser tool that handled our TIFFs without a quality hit. Saved us a whole backend.
The lossless mode for PNG-to-WebP is the key feature I was missing everywhere else. My sprite sheets are byte-for-byte identical after round-tripping.
Replaced three tools I was juggling for archiving. The batch queue and ZIP export were the two features I'd been missing.
No sign-up, no watermark, and actually converts HEIC properly. Every other tool I tried gave me washed-out colors from the iPhone color space.
Converted my entire stock photo library to AVIF overnight. Color fidelity held up well and the files are half the size.
HEIC to WebP in a browser, no server needed — first time I'd found that. Goes into every web performance project now.

WebP has universal browser support and beats JPEG by 25–35% in file size. AVIF is even smaller but lags in older browsers. PNG is the only lossless format that doesn't sacrifice alpha. Knowing this lets you pick the right output — not just the popular one.
Every iPhone since 2016 shoots in Display P3 — a color space 25% wider than sRGB. A naive HEIC→JPEG conversion strips the ICC profile and clips those extra colors, giving you washed-out greens and reds. We embed or remap the ICC profile so your converted file looks exactly like the original.
Drop any file, pick an output format, take the converted result. The entire pipeline runs in a Web Worker on your machine — nothing leaves your device.
