Free online image compressor
Need a smaller photo for an upload form? Add your image and start with a 100 KB target. Choose JPG or WebP, set the maximum quality and review the finished file before downloading. Your images are processed in your browser, not uploaded to our server.
Compress multiple images with one set of controls.
Drag and drop or click to select multiple files.
Choose imagesJPG, PNG, WebP, HEIC and HEIF · Up to 10 images · 20 MB per image · 50 MB total · 40 MP per image
Images are processed locally in your browser using a Web Worker. They are not uploaded to our server.
You can use the compressor above without installing an app or creating an account. The target starts at 100 KB, and you can change it to another value whenever your upload form has a different limit.
Select a JPG, JPEG, PNG, WebP, HEIC or HEIF image from your device. You can add up to 10 images to one batch.
The target size is set individually for each image. Choose JPG for broad compatibility or WebP when the website or form you are using accepts it. Adjust the maximum quality to suit the image.
Start compression, then check the actual output size and preview. Download the result only after confirming it meets the requirements of your upload form.
The compressor searches for a result that fits the target. Some detailed or very large images may not reach 100 KB without more quality or dimension loss. The result tells you whether the target was reached.
JPG is widely accepted for photographs. WebP can be useful where it is supported. JPG does not keep transparent areas, so check the preview when converting graphics.
Some upload forms specify both a file-size limit and required pixel dimensions. A file below 100 KB may still be rejected when its dimensions do not match the form.
Compression runs locally on your device using a Web Worker. The image files you select are not uploaded to our server for processing.
No. 100 KB is the maximum target you are asking the compressor to reach, not a promise of an exact file size. It works towards that limit by adjusting quality and, when needed, image dimensions. Check the measured output size before using it.
You can select JPG, JPEG, PNG, WebP, HEIC and HEIF images. The compressor creates JPG or WebP output.
Yes. Add up to 10 images in one batch. Each image has a 20 MB file limit, the combined batch limit is 50 MB, and each image must be within the 40 megapixel limit.
No. Image compression runs in your browser using a Web Worker. Your selected image files are processed on your device rather than uploaded to ImageCompressLab for compression.
The result will indicate when the target could not be reached at the minimum quality setting. Try a less restrictive target if your form allows it, and always review the image before downloading or submitting it.
