Image Compressor shrinks your images so they load fast and take less space — without visibly hurting quality. Upload a JPG or PNG, pick a quality level, and press “Compress”. The tool rebuilds your image in the browser at the chosen quality and shows you the before and after sizes, so you can see exactly how much you saved. Your image is never uploaded anywhere. Large images slow down websites, eat mobile data and fill up storage. Compressing before you upload or share keeps the quality people can see while cutting the size they have to download. Bloggers compress featured images, sellers compress product photos, and students compress assignment images — the same one-minute step works for all of them. A 3 MB phone photo can take several seconds to load on mobile data; the same photo at 400 KB loads almost instantly, and on a phone screen nobody can tell the difference.
How to use Image Compressor
- Upload an image.
- Pick a quality level — High (0.9), Balanced (0.75) or Small (0.5).
- Press “Compress Image”.
- Check the new size and press “Download”.
- Compare the before and after sizes, then try another quality level if you want it smaller.
Worked example
Example: a 2.8 MB phone photo compressed at Balanced (0.75) becomes about 400 KB — 85% smaller — and still looks sharp on a phone or a website. The tool shows both sizes so you can decide.
Tips for better results
- Balanced (0.75) is the sweet spot for most photos.
- Use High (0.9) for images you will print or zoom into.
- Use Small (0.5) for thumbnails and previews.
- Compress before uploading to your website — it makes pages load faster.
- Compress the original, not a copy of a copy — every round of compression loses a little detail.
Frequently asked questions about Image Compressor
Is the image compressor free?
Yes, completely free — everything runs in your browser, no API key needed.
Is my image uploaded anywhere?
No. Your image is processed locally in your browser and never leaves your device.
How much smaller will my image get?
Typically 60–85% smaller at Balanced quality, with no visible difference on screens.
What format is the download?
JPG. PNG images are converted to JPG, which is smaller for photos.
Can I compress many images at once?
This page compresses one image at a time. Repeat for each image, or use the batch quality setting again.
What is the difference from Image Tools?
Image Compressor only shrinks the file and keeps the original size. Image Tools also lets you change the width and height.
Will compression work on screenshots?
Yes — screenshots are usually PNG files with large flat areas, and they often shrink by 70% or more at Balanced quality.
Does compressing change the image size on screen?
No. Compression only shrinks the file. The image keeps its original width and height — to change those too, use Image Tools.
