Compress images without losing the detail
Shrink photos for the web, email or storage. Move the quality slider and see the exact saving before you download.
This changes the file size — how much space the image takes up. The dimensions and the format stay exactly as they are. To change the width and height instead, use the Image Resizer; to change the file type, use the Image Converter.
How it works
Choose your image
The photo is opened directly from your device.
Pick a format
WebP usually gives the smallest file, JPG is the most compatible.
Adjust the quality
Start around 80% — most photos look identical well below 100%.
The picture never leaves your device
Compressing or converting a photo usually means sending it to somebody else's computer and getting a new one back. Here the work happens in the page you are already looking at: your browser opens the file, the tool rewrites it, and the browser hands you the result.
- Opened from your disk by your browser — not sent anywhere first.
- Held in the tab while the tool works, then dropped.
- Saved to your device by your browser, not by a link to a server.
- Closing the tab clears the working copy completely.
- No account, so nothing is ever attached to an identity.
- No tracking of what you worked on or what was inside the file.
There is no queue and no waiting room. The picture is worked on in front of you and released the moment the tab closes. You can read more about how the conversion runs on your own device, or check our guide to verifying it in DevTools.
What people use it for
Getting under an attachment limit
Most mail services bounce anything over a few dozen megabytes, and a phone photo straight from the camera is often bigger than that.
Shipping a lighter page
Hero images are usually the heaviest thing on a site. Getting them smaller before they reach your CMS is the fastest performance win available.
Sending photos on a weak signal
On hotel Wi-Fi or a poor mobile connection a full-resolution photo can sit at sending for minutes. A smaller copy goes through in seconds.
Preparing marketplace listings
Selling platforms set their own caps on size and dimensions. Get inside them before you start filling in the form.

When something goes wrong
Damaged files, and formats outside the list above, stop with a plain message rather than a spinner that never finishes. If a picture opens in your gallery it will normally open here.
The format is not supported. Convert it to PNG or JPG first, or try one of the other image tools.
Why not an upload site
An upload-based tool is a form that posts your picture to someone else's machine. Take that step out and a lot of small annoyances disappear with it.

Questions
How much can I reduce a photo without it looking worse?
For most photographs, quality between 75% and 85% produces a file that is dramatically smaller and visually indistinguishable at normal viewing size. Below 60% you will start to see blocky artefacts.
Should I use WebP or JPG?
WebP typically produces a file 25 to 35 percent smaller than JPG at the same visual quality, and every current browser supports it. Choose JPG only if the image must open in very old software.
Will compressing remove my photo's location data?
Compression re-encodes the image, which discards most embedded metadata including location information. If removing metadata is your main goal, the Metadata Stripper tool does this explicitly.
Is there a file size limit?
No fixed limit is imposed by the tool. The practical ceiling is how much memory your device has free, because the whole job runs inside this browser tab.
Does it work without an internet connection?
Yes, once the page has loaded. Nothing is fetched while you work, so a dropped connection does not interrupt a run.
Do I need an account or an email address?
No. There is nothing to sign up for, and nothing is ever attached to an identity because no file leaves your device.
