About the Image Compressor
The Image Compressor makes photos and graphics smaller without making them look worse. Most images from phones, cameras and design tools are saved with far more data than the eye can see. By re-encoding them intelligently, you can usually cut the file size by 50–80% while the picture stays crisp.
Unlike simple compressors that blindly apply one quality setting, this tool checks every result against the original. If compression would remove noticeable detail, it automatically raises the quality until the image looks right, so you never download a blurry or blocky picture by accident. JPG and WEBP photos are re-encoded with optimized quality, and PNG graphics are reduced with smart color quantization that keeps transparency. If an image is already optimized, the original is kept instead of producing a larger file.
By default the output keeps the same format as the original, but you can also convert to JPG, PNG or WEBP (the smallest format for websites). Drop many images at once, use the Compare slider to inspect the result, and download everything as a ZIP. Everything runs in your browser, so your photos are never uploaded.
Choosing a preset
- High quality: photos you will print or put in a portfolio.
- Balanced: the right choice for most websites, blogs, emails and online stores.
- Smallest: when every kilobyte counts, such as image-heavy pages on slow mobile connections.
Two settings that save the most space
- Max width: a 4000-pixel photo from a phone is far bigger than any screen needs. Setting 1600 or 1920 often reduces the file more than the quality slider does.
- WEBP output: for websites, WEBP is usually smaller than JPG at the same visible quality, and all modern browsers display it.
Example
Twenty product photos of 3–5 MB each, with Balanced, WEBP and a max width of 1600, often end up around 150–300 KB each. Your pages load faster and the store looks the same.
If the result would look worse, the tool keeps a higher quality automatically. Need an exact limit such as 100 KB? Use Compress Image to KB.
How to use the Image Compressor
- Drop one or more JPG, PNG, WEBP, GIF, BMP, AVIF or HEIC images into the upload area.
- Choose a compression level (Balanced is recommended) and, optionally, a maximum width.
- Use the Compare slider to check that the compressed image still looks sharp.
- Download images one by one or all together as a ZIP.
Frequently asked questions
Will compression reduce the quality of my images?
With the Balanced or High quality level, results are checked automatically and stay visually identical in almost all cases. Use the Compare slider to see for yourself.
Which format gives the smallest files?
WEBP is usually 25–35% smaller than JPG at the same quality and supports transparency. Choose JPG when a website or form only accepts JPG.
Why was my original image kept?
If an image is already well optimized, re-encoding would make it bigger or worse, so the tool keeps your original file.
How do I compress to an exact size such as 100 KB?
Use our Compress Image to KB tool, which automatically finds the best settings for a target file size.
