Compress, convert and upscale images, or turn a video into a GIF — without uploading a single file. Everything runs on your device with WebAssembly. No signup, no size limits, private by construction: disconnect your internet after the page loads and it still works.

Change format between JPG, PNG, WebP and SVG — pick the output per image.
Turn a clip into a GIF or animated WebP — trim, fps, size, colors.
Enlarge photos ×2 or ×4 with Real-ESRGAN AI running on your device.
Most online media tools upload your file to a server, process it there, and send it back. Your image or video sits on someone else's hardware until they decide to delete it, and you have to trust a privacy policy that this is fine.
Tinier does the work on yourdevice. The compression, conversion, video and AI engines are compiled to WebAssembly (and WebGPU for upscaling) and run right in the page. Nothing is uploaded — the honest test is that you can turn off your internet after the page loads and every tool keeps working. Privacy here isstructural, not a promise.
It is also fast: for files under 10 MB, skipping the upload-and-download round-trip makes local processing quicker than a server tool. And it is free — no account, no rate limit, no watermarks, no size paywall.
Yes. Every tool is free with no account, no rate limit, no watermarks and no size paywall. A future Pro tier may add server-side extras, but the browser tools stay free.
No. Every tool runs entirely in your browser using WebAssembly (and WebGPU for the AI upscaler). Your files never leave your device — you can disconnect your internet after the page loads and everything still works.
Compress images, convert between image formats (including SVG), turn short videos into GIF or animated WebP, and upscale photos with AI — all in the browser, all private by construction.
