Image Compressor

Add your photo by dragging it onto the tool or clicking to browse — JPG, PNG and WebP are all supported, and you can select several at once for batch compression. Adjust the quality slider (lower means a smaller file) and, if you want, resize the image or change its output format. The tool re-encodes each picture instantly and shows the original size next to the new size, then you download the result individually or as a ZIP.

Two things shrink a file: lowering the quality and reducing the dimensions. For email, resizing to a max width of around 1600px at 70-80% quality usually drops a multi-megabyte phone photo under 500 KB while still looking sharp. For the web, do the same and export as WebP for the smallest file. Watch the before/after comparison and nudge the quality down until you hit the size you need.

Yes. Making an image smaller in dimensions is essentially lossless to the eye — the visible quality loss comes from over-compressing, not from resizing. Resize by percentage or set a maximum width and height (the aspect ratio is kept so nothing gets stretched), and keep quality at 80% or higher. The before/after readout lets you confirm the file is smaller without pushing the quality so low that artifacts appear.

For photographs, use JPEG or WebP at roughly 75-85% quality — a good balance of small size and sharp detail. For graphics, logos and screenshots with text or flat color, PNG (or WebP) keeps edges crisp, though PNG files are larger. WebP typically beats JPEG and PNG on size and is supported by every modern browser, so it's the best default for websites. Choose 'keep original' if you simply want to compress without converting.

Yes to all three. The compression runs entirely in your browser with the Canvas API — your images are never uploaded to any server, which is why we can say your files never leave your device. The re-encode also strips EXIF metadata such as GPS coordinates and camera info. Once the page has loaded you can disconnect from the internet and keep compressing, since there are no network calls involved.
