Fast & Private Image Compressor

Most online compressors send your photo off to a server, work on it there and send it back. That means a copy of your ID scan or family picture sits on someone else's computer, maybe in another country, for however long they keep it. This one works differently. The compression code loads with the page and runs on your own device, so the image is never uploaded, never crosses a border and is never stored by anyone. If you care about privacy laws like GDPR, that's a comfortable setup, because nothing leaves your device in the first place.

It also skips the usual quality slider. Upload forms care about kilobytes, not percentages, so you tell the tool how big the file can be and it finds the highest quality that fits. If the photo would start to look blotchy first, it trims the dimensions a little and tries again. A form that wants something tiny can use the 10KB page, and most general upload limits are covered by compressing to 200KB.

When a target really can't be reached, you'll see the closest size it managed, clearly marked. It won't say a file is under the limit when it isn't. Sending pictures to a group chat or attaching them to a mail? The WhatsApp and email pages start with sizes that suit those jobs.

You can drop in JPG (or JPEG), PNG and WebP files, and save the result as WebP, JPG or PNG. WebP is usually the smallest for photos at the same quality and opens in every modern browser. JPG is the safe choice when a site only accepts .jpg. PNG is lossless, so it's great for screenshots and logos, but the only way it can hit a small target is by getting smaller in pixels.

Transparency is worth a quick thought. WebP and PNG keep a see-through background, while JPG fills it with white. Camera details like GPS location and phone model aren't copied into the new file either, which is a nice bonus if you're posting the picture somewhere public.
