Frequently asked questions

No. When you upload a file here, it is opened and processed in your browser and never sent to us. Your browser does the work and hands you the result — which is why there is nothing to wait for, nothing stored and nothing to delete. You can confirm this yourself: load a tool page, disconnect from the internet, and it still works.

When you upload a file here, it is opened and processed in your browser and never sent to us. Your browser can decode, resize and re-encode images by itself, so the file is never sent anywhere — there is no server on our side that receives it. That is also why there is no size limit and nothing to wait for: the work starts the instant you add a file and finishes as fast as your device allows. When you close the tab, the files are gone from memory. Switch off your connection after a tool page has loaded and it keeps working.

No cap is set by us. Files of any size, in any number — the practical limit is the memory your browser can use on your device. Phones handle batches of a few hundred photos; laptops far more.

Safari and iPhones open HEIC natively. Chrome, Edge and Firefox do not, so on those browsers the page loads a small open-source decoder from this site. If a single file still fails, it is usually a burst sequence, a 10-bit HEIF variant or a damaged file. The rest of the batch continues.

A little, and you control how much. Between 75% and 90% the result is visually identical to the original at normal viewing sizes. The tool shows the new size next to every file as you move the slider, so you can judge the trade-off before downloading.

For JPG, PNG and WebP, no: the metadata is cut out of the file and the image data is copied byte for byte. The one exception is a JPG that relies on the EXIF rotation flag; it is rotated to match and re-encoded at 92% so it does not appear sideways.

When you choose the next step — for example Compress after HEIC to JPG — the finished files are placed in your browser’s local storage on your device for a few minutes and picked up by the next page. Nothing is re-selected and nothing is uploaded. Each step can also be downloaded on its own.

Advertising in fixed, labelled spots outside the working area, never above or over a tool and never while files are processing. Ads never see your files.

One first-party entry in your browser’s local storage records your cookie choice and your light or dark theme. Analytics and advertising storage are off until you accept them in the banner, and you can change your mind at any time on the cookie settings page.

Once a tool page has loaded, processing needs no connection. Disconnect and keep working. Reloading the page does require a connection.

To your browser’s default download location. On iPhone and iPad, open the Files app and look in Downloads; on Android, the Downloads folder; on a computer, the folder your browser is set to use.

You do. We claim no rights over anything you process and never receive a copy of it.

Current versions of Chrome, Edge, Firefox and Safari on desktop and mobile. If a browser lacks a capability a tool needs, the tool says so rather than falling back to a server.
