Ever taken a photo on your phone and found that the file is several megabytes larger than you need? Large images can slow down web pages, take up storage space, and cause problems when you need to attach a photo to an email or upload it to a website with a strict file-size limit.
Our JPG Compressor helps you reduce the size of your JPEG images directly in your browser. You can adjust the compression level, compare the result with the original, and download the smaller file when you are happy with the result. There is no need to install software or create an account.
The tool starts at a balanced 80% quality setting, with a slider ranging from 10% to 100%. If adjusting quality is not enough, you can also limit the image width in pixels to reduce its dimensions and bring the file size down further.
The best quality setting depends on the image and how you plan to use it. A photograph with smooth backgrounds may compress differently from one filled with fine textures, text, or intricate details. Start at 80%, then compare the results before deciding which version to keep.
100 KB or 50 KB, lowering the quality may help. However, these settings do not guarantee that the image will meet the limit. You may also need to reduce its pixel dimensions.Tip: Start with 80% quality and lower it gradually if the file is still too large. Compare both the final file size and the image itself rather than relying on the percentage alone.
.jpg or .jpeg file. If drag-and-drop is supported by the current interface, you can also drop the image onto the page. The tool processes the image using the default 80% quality setting and displays a preview.1200 or 1600 pixels, in the Max width field. The current tool settings support values from 50 px to 8000 px. Leave the field at 0 to keep the original dimensions, provided the tool uses this value as its default no-resizing option.compressed- prefix, making it easy to distinguish from your original image.Sometimes, after you upload an image or change the quality setting, the tool displays a yellow ⚠️ Already optimized message with 0% savings. This can happen when the image has already been compressed or when the new encoding does not produce a smaller file.
Saving a JPEG again does not always reduce its size. Depending on the original image and the selected quality, the newly encoded file may be the same size or even larger. Re-encoding also cannot restore details that were lost during earlier compression.
If the tool detects that the new file is equal to or larger than the original and no resizing has been requested, it may keep the original instead of replacing it with a larger version. This avoids increasing the file size without providing a benefit.
To try reducing the size further, lower the Quality setting gradually or enter a smaller value in Max width. Then check the result again. The exact outcome depends on the image, so no particular setting guarantees a smaller file every time.
Depending on the image format and your goal, another tool may be a better fit. Here are a few options to help you reduce file sizes or prepare images for different uses.
The tool is designed to process images locally in your browser using web technologies such as HTML5 Canvas. This means image processing does not need to involve uploading your photo to a server. To confirm that your images never leave your device, the tool's actual code and network requests should also be checked for any file uploads or external transfers.
Not necessarily. If Max width is set to 0, the tool should preserve the original pixel dimensions when that setting means no resizing. If you enter a smaller maximum width, the output dimensions may change while the image's proportions are maintained, depending on how the tool handles resizing.
You can, but it is generally better to adjust the settings in one session and download the final image once. Repeatedly saving and recompressing a JPEG can introduce additional quality loss. Start with the original file, experiment with the Quality slider, and adjust the dimensions if necessary. Once you are happy with the result, click Download compressed.
There is no meaningful difference between the two extensions. Both .jpg and .jpeg refer to the same JPEG image format. The shorter .jpg extension became common because older versions of some operating systems limited file extensions to three characters. Both extensions can be used with this tool, provided the uploaded file is a valid JPEG image.
