About the Image Compressor
The Image Compressor reduces the file size of your pictures so they load faster, upload more easily and take less storage. Choose a quality level from high quality to maximum compression and compare the size before and after. The image is processed in your browser, so it is not uploaded to a server.
How to use the Image Compressor
- Select an image from your device.
- Choose a compression quality level.
- Click Compress, check the new size and download the result.
Frequently asked questions
Will compression reduce image quality?
Higher compression gives a smaller file but can reduce detail. Medium quality is a good balance for most photos.
Is my image uploaded anywhere?
No. The compression happens locally in your browser, so your image stays on your device.
How the Image Compressor works
Choose an image, pick a quality level and press Compress Image. The tool redraws the image on a canvas inside your browser and saves it again as a JPEG at the chosen quality. Four levels are offered: high (90%), medium (70%, recommended), low (50%) and very low (30%). Images wider than 2,000 pixels are also scaled down to that width, which cuts the file size further.
Your image is processed on your device and is not uploaded to a server. The result downloads as compressed-image.jpg, and the page shows the original and compressed sizes.
Worked examples
A 3.5 MB phone photo compressed at the medium level often becomes well below 1 MB, depending on the image. A photo with a lot of fine detail shrinks less than a simple picture with large flat areas.
Many online forms and portals ask for a photo or a signature below a size such as 100 KB or 200 KB. Try medium first and move to a lower level if the file is still too large.
Tips and common mistakes
- Start with the recommended level and compare the results. Lower quality means a smaller file but more visible blur or blockiness.
- The output is always JPEG. A PNG logo or screenshot with a transparent background may look different after conversion.
- Keep the original photo. Compression removes detail that cannot be restored.
- Smaller images load faster, which improves website speed and uses less mobile data.
- If you need exact dimensions for an application form, check the required width and height as well as the file size.
More questions about the Image Compressor
Is my image uploaded anywhere?
No. The file is read and compressed in your browser, and it stays on your device.
Which quality level should I choose?
Medium is a good balance for most photos. Use high if quality matters most and very low only when size is the priority.
Does it support PNG or WebP?
You can select an image file, but the output is saved as a JPEG.
Why is my file not much smaller?
Images that are already compressed, or that are small in dimensions, have little room to shrink. Try a lower quality setting.
