Why process files in the browser?
Never uploaded
Processing happens on your device. Files never reach a server
No limits
No caps on file count, size or number of runs
No queue
Nothing to upload or download, so work starts instantly
Works offline
Once the page is open, it keeps working without a connection
Typical online converters upload your file to a server, convert it there, and make you download the result. That ties processing time to your connection speed, forces size caps and daily quotas, and above all puts your private photos and meeting recordings on someone else's server. This site uses WebAssembly and WebCodecs to run the conversion itself inside your browser. Files never leave your device, and there are no caps and no waiting.
Frequently asked questions
Are my files really not uploaded?
Correct. All conversion and compression runs inside your browser using WebAssembly and WebCodecs; nothing is sent to this site's server. You can verify this by keeping the Network tab of your browser's developer tools open while processing: no file upload occurs.
Is there a file size or usage limit?
The site imposes none. Processing uses your device's memory, CPU and GPU, so the practical limit is your hardware. As a guide, most devices handle images of tens of megabytes, audio of several hours, and video of several gigabytes.
Which browsers are supported?
The image and audio tools work in current Chrome, Edge, Safari and Firefox. The video tools rely on the browser's built-in encoders (WebCodecs), so we recommend desktop Chrome, Edge, Safari 17+ or Firefox 130+. If your browser is not supported, the page tells you.
Does it work on phones?
Yes. Video conversion uses a lot of memory, though, so long videos are best processed on a desktop. Image conversion and compression run comfortably on phones.
What happens to EXIF data such as location?
Images are re-encoded, so EXIF metadata such as capture time, GPS location and camera model is not included in the output. This is also a handy way to strip location data before posting to social media.
Does it cost anything?
No. It is free and requires no account. Running costs are covered by ads.
Do you collect error reports?
Only statistics that help us fix bugs. What is sent: the tool you used and the settings you chose (output format, quality, etc.), your device specs (GPU, memory, core count), the input format with a rough size, how many files succeeded or failed and how long it took, and the error type and details when something fails. The files themselves, file names, text or subtitles added to a video, and IP addresses are never sent. The data goes only to this site's own server, never to a third-party service. You can turn it off at any time with the switch under "Help us improve the service" at the bottom of each tool page.
Help us improve the service
If a conversion fails, sending us the circumstances helps us track down the cause. Knowing which devices and formats fail most often, and how long processing takes, lets us revise the supported formats and fix the bugs behind them. If you don't mind, leaving this on is a real help.
